The Project
Shortdescription
BACKGROUND
Mobility and mobile
applications are becoming essential, both in our private life and our
pursuit of business. Especially travel and tourism are domains in which
individuals and groups are mobile and visit cities, regions, and places
that they like to discover and learn more about. With the availability
of new and powerful mobile devices and evolving network
infrastructures, mobile systems, and applications can accompany the
mobile user in order to support and inform them on their way.
One
of the central aspects of being mobile is the constantly changing
position of the user and along with this a changing user situation.
Consequently, a mobile application needs to meet these changing user
requirements. If an application has access to the current position of
the tourist, the mobile application can provide location-based
information right on the spot and by this inform, help, or warn the
user just at that position. This can be for example informative data
that helps the user experience the spot and the surroundings, but also
assistive, e. g., to become aware of interesting spots or be warned
about upcoming obstacles on the way. What is important is that each
individual tourist has individual needs, interests, and preferences
that should be met.
APPLICATION SCENARIO – LOCATION-BASED AND CONTEXT-AWARE MULTIMODAL HIKING GUIDE
In
our application scenario, a hiker can borrow a device from
the local tourist office that is equipped with a Galileo receiver and
the mobile hiking guide application. Before the beginning of the tour,
the key preferences are entered for each single visitor or for a group
of hikers. This includes among others, the preferred language, the age
of the adults and children in the group, the hiking experience, and the
familiarity with the area. Based on this initial information the system
suggests a tour and presents a tour description, the sign-posts to be
followed, and a map with the tour on the mobile device. Using the
Galileo positioning system, the mobile device can always locate the
hiker(s) and visualize the current position on a geo-referenced map on
the mobile display. So, during the entire tour the hikers can see and
confirm their own position on the map in relation to the tour. Whenever
an interesting point in the tour is reached this is also indicated on
the map. This can be for instance, navigational information when the
tourist reaches a branch of the trail, to indicate a turn and navigate
the tourist in the right direction. In addition, small icons on the
mobile device’s display show so-called points of interest (POIs). These
can be shelters or Alpine Huts, or places where very rare plants grows.
Depending on the hikers’ preferences they indicate the availability of
additional information along the way about flora, fauna, and history –
whatever seems to be suitable for the profile of the hikers. Using the
Galileo positioning system, even in the remoteness of the mountain
scenery our system can provide information right on the spot like a
unique type of plant that grows here, a specific stone that can be
found, or a funny story that happened here years ago with text and
pictures on the device. Using the storage capacities of today’s mobile
hardware the device stores all necessary information about the tour
itself. While walking on the trail the mobile application selects the
context-aware information on the base of the current location and the
tourists preferences. In areas in which a connection of the mobile
device over a wireless point-to-point network is possible, which is the
case in most of the mountainous areas of the Montafon region, the
tourist can additionally connect to a speech server to receive the most
up-to-date information about the current spot.
As the hikers
need their visual attention for looking on the way and to enjoy the
landscape, the system adjusts its output modality to the context
situation of the hiker. With sounds the hikers can be navigated
acoustically. Distinct sounds provide warning signals when the hikers
wander away from the trail and also indicate that a branch is appearing
and ant the next right turn should be taken. Depending on the hikers’
profile they can receive different sound signals if a spot of interest
is approached and additional information is available. Again, this
information can be presented with different modalities such as image
and text but also by means of speech and music. Presenting acoustic
information allows the hikers to look at whatever is interesting at the
spot and at the same time listen to a description or music associated
with it. For visually impaired people a speech output of the same
information that is provided on the visual display allows them to share
the same hiking experience, for example in a group of sighted and blind
hikers.
With such context-aware and multimodal information
provision the system gives the hikers their personal experience of the
Montafon scenery.
REQUIREMENTS
For
the development of a Location-Based and Context-Aware Mobile Multimodal
Hiking Guide Application (Loccata) we find the following requirements
for the software development and demonstration project:
•
Precise localization of the tourist: When walking around outdoors in
mountainous areas every single meter can be of high importance, both
for exactly locating the sightseeing spot of interest to the user but
also for determining the branches of hiking trails in the mountains.
Therefore, the mobile application needs to locate the user’s current
position as precise as possible. Here, accuracy down to the meter range
is needed to be able to present information to the user, which really
meets the current user situation on the current position.
•
Reliable localization of the tourist: Especially in remote areas it is
important that the tourist can trust the current position shown on the
mobile device. Also the tourist needs to know if the position is up to
date and the associated preciseness at the current moment. Only by
this, it is possible to develop a mobile tourist guide in which hikers
can trust with regard to the local context.
• Visualization of
the hiking trail: To give the mobile user a visual impression of the
trail a geo-referenced map is needed. On this map, the tour information
needs to be presented. This includes the trail, the branch connections
and the estimated time the hiker needs to reach the end of the tour,
together with the hiker’s current position.
• Visualization of
points of interest: Along with the trail information, the map needs to
indicate interesting spots along the path. On the map, so-called point
of interest (POIs) show where the next shelter or an Alpine hut can be
found. According to the preference of the tourist different types of
POIs are shown on the map to indicate different types of location-based
information along the way such as the growing of a rare plant or a
historic place.
• Context-aware location-based information: To
meet the specific tourists’ needs the location and the context need to
be exploited to deliver the most targeted information. Therefore a
simple user profile specifies the tourist’s general preferences and a
tracking of the current user context such as place and time. The
available content needs to be annotated and enhanced with metadata such
that a context-aware information selection can be carried out and the
tourist receives not only a localized but also individualized
information according to the current context and preferences.
•
Multimodal information presentation: Hiking tourists typically need
theirs hands and eyes free for the hiking task: they watch the track,
enjoy the panorama, and also sometimes need hands to hold on to grips.
Therefore visual information is not helpful at all times, rather
acoustic signal and voice information to help, warn, and inform the
tourist are in need.
• Connected and unconnected mode: Even
though the Montafon region enjoys a good infrastructure of cellular
networks in the alpine regions, the system should be able to work both
in a connected and an unconnected mode. In a connected mode the tourist
can use a cellular network connection to retrieve and receive up do
date location-based information for the tour. The basic trail
information, however, should be available on the mobile device.
MAIN PROBLEMS
With regard to existing solutions and technology we find the following main problems:
•
Impreciseness and reliability of the American GPS system: Even though
it is possible today to locate mobile tourist with the existing GPS
system, the impreciseness of the position is an obstacle for providing
reliable and precise location-based information for tourists walking
outdoors. For example, due to GPS shadows a tourist could find
himself/herself a few hundred meters away from the real position on the
map shown on the mobile device. Consequently, and information provided
at the current localized position, for example, a story about a
mountain lake, for which the real world object can not even be seen by
the tourist from his/her current position.
• Mobile Systems today
are not context-aware: Most of the mobile services we find today only
exploit the user’s position to indicate the position on a
geo-referenced map on the mobile device. These systems consider the
position as the central but often as the only context element,
delivering the same information to all users. This however, does not
necessarily meet today’s individual tourists needs. The local position,
however, is a central but not the only element out of the tourist’s
current situation. The time of the day in combination with the current
location allows delivering an even more targeted service. With the
additional context information such as the time and the current weather
conditions (available from a weather service) the system can provide a
context-aware mobile service to the tourist. Today’s systems, however,
do not comprehensively use and exploit a user profile and local context
to provide and context-aware information to the mobile tourists.
•
Mobile systems rely on visual information presentation: Mobile
applications today often assume the use of a small portable mobile
device with an integrated small graphical display. The information
provision on the device is based on visual information shown by means
of maps, points, links, small text, and images. However, this does not
necessarily meet a mobile user’s situation, as he or she may currently
needs his/her hands and eyes for other things than to hold on and look
at the mobile device. Current systems only provide visual information
and do not provide any auditive support.
PROPOSED SOLUTIONS
In
the proposed software development and demonstration project we will
exploit the precise and reliable localization information of Galileo
and, based on this, develop an innovative mobile application that
provides location-based context-aware information to tourists of
mountainous regions. The proposed solution for the development of a
Location-Based and Context-Aware Mobile Multimodal Hiking Guide
Application (Loccata) comprises two main parts: (1) The development of
a context-aware location-based mobile system platform and (2)
Development of location-based and context-sensitive content for the
mobile hiking tours. Based on the system platform the content developed
can be used by the mobile tourist on his/her hiking tours.
DEVELOPMENT OF A LOCATION-BASED AND CONTEXT-AWARE MOBILE SYSTEM PLATFORM
The
technical basis for the context-aware location-based mobile application
forms a modular mobile application platform. This platform realizes the
typical tasks of a location-based mobile application. The development
will include modules for realizing the location sensing based on the
available Galileo receivers, the connection to a server application
over cellular networks, the visualization of the tourist’s location on
a geo-referenced map, the visualization and presentation of points of
interest on the map, and a multimedia presentation of the
location-based information. The different system modules are integrated
in one platform and form the software basis for the proposed mobile
hiking guide.
Basic modules of the platform that has been
developed by the contractor OFFIS will provide functionality for the
specific requirements of mobile multimedia applications, such as
location-aware mobile navigation and orientation support, multimodal
user interface, and location-based information and services. For the
developed mobile hiking guide, within the software development project,
the platform is extended and applied in the specific application domain
and targeted to mobile context-aware applications in the domain of
tourism. The software development of the mobile system is based on the
experience of the consortium in the field of mobile application
development. Existing prototypes and concepts are input to the tender.
The contractor OFFIS is part of a Center of Excellence for Mobile
Applications (Niccimon) [Nic04]. Within the Niccimon research center
the contractor OFFIS works in close cooperation with the Institute for
Communications Technology in Brunswick, Germany, and the Institute of
Communications Engineering in Hanover, Germany. The results of this
research resulted in a design of a modular mobile system development
platform [BBK+04]. The contractor has also expertise in geographic
information system (GIS) from an earlier research project InterGIS.
This experience of OFFIS includes also research in the field of
personalized multimedia applications [Bo03a, Bo03b, BW03],
context-aware and personalized mobile systems and applications
[BBK+04a, KB04, SB04a] as well as multimodal user interfaces [DKG02,
Kl03]. The contractor OFFIS has applied their research work in several
prototypes and demonstrator applications [KKRB04, KKB04, SB04b].
Research
results have been achieved also in the area of meeting the different
mobile devices needs for hypermedia and multimedia presentations
[SB05]. The project proposed in this tender continues and extends the
mobile system platform and its modules and provides the opportunity to
apply and transfer the technology meeting the individual tourists needs
in the commercially promising Mountain Area of the Montafon.
The solutions proposed are:
•
Precise and reliable localization of the tourist: The mobile device is
equipped with a receiver for the Galileo positioning system. This
position information is encapsulated in an internal format and
exploited by the other modules of the mobile client application. At the
beginning of the development, the raw position information could also
be supplied by a “of-the-shelf” GPS receiver and afterwards replaced by
facilities provided by ESA. The localization is developed such that one
gains an abstraction from the actual positioning system.
•
Visualization of the hiking trail: For the visualization of the hiking
trail a geo-reference map developed a mobile GIS module to provide
support for orientation. In order to help the tourist to orientate
himself or herself, the map is centered on the users position and the
position of the user is displayed on the map itself.
•
Visualization of points of interest: The mobile application provides a
management and visualization of the POIs along the trails. These POIs
can be stored on the mobile device or dynamically loaded from a server.
Each POI comprises the position information where the POI is located,
an icon to represent the POI in the map, and a referrer to the POI’s
content information. The presentation of the POI icons helps the mobile
user to get an overview about interesting spots in his or her
surrounding. POIs themselves are grouped along different topics, e. g.,
shelters, huts, branches, so that the user can select and view only
certain topics of interest and thus avoid information overload.
•
Context-aware information presentation: Depending on the context, the
information presented about the current spot is selected meeting the
user’s profile and context. For the representation of the
location-based information hypermedia documents are created. These
documents are dynamically composed according to the user profile and
current context.
• Multimodal information user interface design:
For the mobile hiking guide an additional auditory is provided. With an
speech representation of the location-based content and a support for
auditory signals, a seamless combination of visual and auditory
elements within the user interface can be achieved. Objects of interest
in the real life environment such as POIs are hence visually and
auditory augmented. For the project, the user interface of the mobile
hiking guide is designed such that the output modalities meet the
actual tourists task when walking on the trail.
• Connected and
unconnected mode. The mobile hiking guide is equipped with an access to
a cellular network such as GPRS over GSM. Over this mobile connection
the tourist can reach a speech server which delivers up-to-date
location-based information. In an unconnected mode the mobile device is
loaded with sufficient information to support the tourist with
information about the trail and the surroundings of the trail as well
as some location-based information. Over the mobile connection more
current or additional information can be retrieved.
DEVELOPMENT OF LOCATION-BASED AND CONTEXT-AWARE CONTENT FOR THE MOBILE HIKING TOURS
For
the content development for the location-based hiking guide the
contractors Schruns-Tschagguns Tourismus and Stand Montafon bring high
expertise in the planning and production of content for the mobile
hiking guide application into the project. The contractor
Schruns-Tschagguns Tourismus is developing touristic attractions and is
investing in infrastructure for tourism and is maintaining attractions
like the “Aktivpark Montafon“, a concert hall, swimming pools and
football grounds. The contractor is highly interested in the
development and evolvement of new tourist concepts. Within the proposed
project, the contractor Schruns-Tschagguns Tourismus provide their
background in the professional development of concepts and their
implementation for the mobile hiking guide system.
The
Montafon Region is an excellent choice for the development of such an
innovative application, as the GIS data for the large net of trails is
to the most part already recorded. For the maintenance and planning of
the forests in the Montafon almost 10 GIS are in use. The contractor
Stand Montafon is already participating in the development of a
comprehensive digital geo data basis for the Montafon Area that is
continuously updated and extended. All geo data is collected by the
communities and is centrally maintained and preprocessed by the
contractor Stand Montafon. To use and exploit the geo data, the Stand
Montafon has established a service center for the maintenance and usage
of the geo data for the Montafon local authorities.
Also
responsible persons for the tourist development of the Montafon region
are standing strongly behind the proposed project. Based on the
knowledge of the Montafon area and the existing content in the field of
geo-reference maps, trail descriptions, and other information material
of the area, the content of the projects can easily be composed to
develop the content for selected hiking trails, points of interest
providing a context-aware usage by the mobile tourist.
The solutions proposed are:
•
Development of selected hiking tours: From more than 500 km of
sign-posted hiking trails in the Montafon´s mountain ranges,
interesting tours are selected that would attract different types of
tourists. The selected tours represent a well-chosen set which
illustrates the variety of different trail types and levels in the
area. The trails are selected and implemented such a way that the
demonstrator of the mobile hiking guide shows the versatility of the
system.
• Development of geo-referenced information: For the
selected tours a track of the Galileo positions on the way are
recorded. Also the positions of the sights and spots of interest are
recorded. With these positions the information that is presented to
the tourist along the way is associated such that the system can select
and present the most suitable location-based information to the
tourist. Based on the available GIS data of the region the geo data is
selected and, where necessary, additional data is collected or enhanced.
•
Context-aware location-based information creation: For the different
trails with their many POIs on the way the corresponding location-based
information like pictures and description, needs to be collected and
edited. This part starts out from a detailed elaboration of a
storyboard for the location-based and context-ware hiking trails. Here,
as far as possible existing material from the contractors from
Schruns-Tschaguns and Stand Montafon are used. Wherever needed, the
material is systematically extended and enhanced. For the selected
tours all context-ware information is prepared. Texts and images are
selected from the existing tourism databases and extended by newly
selected material. This information is processed in to geo-reference
hypermedia documents for each of the selected trails.
•
Development of auditive information: For selected points of interest,
the location-based information is developed also in an auditive
fashion. Selected material is prepared such that a speech
representation complements the elaborated visual content which can be
listened to during the trail.
The central innovations that the proposed application bears are:
•
Based on the Galileo GNSS the localization of a tourist outdoors in
remote areas at different altitudes is possible. This provides the
tourist with very precise and reliable navigation information and
information about the trails and the different POIs along the trail.
• Besides the location, the mobile hiking guide takes the user context into account when selecting and presenting POIs.
•
Mobile information systems often present their information in visual
form. The multimodal user interface design of the proposed application
takes the specific task of hikers, i. e, walking on small trails that
also carry some risk to take the wrong way of unintentionally leave the
path, into account.
• A detailed elaboration and implementation
of geo-referenced, location-based tourist information that allows
tourist to access individualized information on the trail, depending on
his/her personal context and profile while hiking in Montafon region.
ACTIVITIES DESCRIBED IN THE STATEMENT OF WORK
In
the following, we first describe where the application development
proposed in this tender meets the work activities of the proposed
project with the Statement of Work. Below we also describe the
feasibility of the project and the development risks.
WORK ACTIVITIES
The
project in this tender meets the “Focus on stimulating technological
innovation and the opening-up of novel market segments!” of the
Statement of Work. The developed application will allow to “experiment
with new tools and approaches”. Even though tourism is a big market
segment in Austria, mobile application for tourists fall into the
section “Niche Markets, scientific and innovative applications” of the
Statement of Work. With the availability of the “Galileo application
solution (GNSS)” the tender proposes a “Software development and
demonstrator project” in the specific domain of hiking tourism. Part of
the work will be an “Application scenario modeling” that allows to
understand the specific application domain and also derive results and
experience of the applicability of the developed concept for the
applcition domain. With the location-based context-ware multimodal
hiking guide, we develop an “Innovative solutions for tourism”.
SELECTION OF A PREFERRED CONCEPT
Modular
system platform: When developing mobile applications, e.g., mobile
games [BKW03, KKRB04] or tourist information systems [KBB04], one of
the central discoveries is that different applications often share
similar basic application requirements. In our developments at the
Niccimon research centre, we identified different autonomous tasks and
modules concerning location-sensing, location-visualisation,
presentation of points of interest, etc. Based on these results, we
developed a flexible, modular, mobile system platform [BBK+04].
Following the mediator-wrapper-architecture approach, the Niccimon
platform provides a mediator module which is governing, the per se
autonomous, different wrapped applications treating the above-mentioned
topics. The integrated application modules cooperate with each other
via distinguished interfaces provided by the mediator. The interfaces
provide access to functionality such as live cycle control,
visualisation, network communication, and inter-component
communication. This concept enables us to be flexible and powerful at
the same time. This prototype and the available prototypes applications
[KKRB04, KKB04, SB04b] are the selected concept for the system
implementation which is brought into the project.
Theme-based
context-aware hiking tours: Preferred concept from the application
perspective is to provide a support for the hiking tourist meeting the
individual tourist’s needs and preferences. Here a previous project of
theme base hiking trails has proven to be a good start for the project
in the region. In this project “monta-phone” local tourist information
can be retrieved over mobile phones. Based on these first experiences
the concept is the selection of trails and POIs is used in the mobile
hiking guide. The selection of a limited but interesting set of trails
and POIs the content production for the proposed project will deliver
an incisive content for the mobile hiking guide and consequently invite
future partners for a commercial application of the system. With the
development and successful demonstration of the system, the application
lays the base for its transfer into commercial tourist offers in the
Montafon region. The contractors Stand Montafon and Schruns-Tschagguns
Tourismus are highly interested in the transfer of the project results
into the local tourism domain.
FEASIBILITY OF THE PROJECT
The
experience of the consortium in the development of mobile systems and
applications as well as long term experience in touristic development
of the Montafon area and managing of projects with touristic background
forms a strong background with regard to the technology used and
development and also with regard to the application domain and content
production.
The system platform that is input to the project
forms a basis for the software development of the mobile hiking guide
in the specific application context. The prototypes of the contractor
OFFIS that have been developed in earlier research projects show the
feasibility of the concept itself and allows to expect the feasibility
of the software development tasks ahead.
The content brought
into the system is also well defined enough to work with. The high
expertise in collecting, maintaining and using geo data, and developing
touristic material and concepts by the contractors, allow to quickly
start the content production and it is expected that the content
production tasks will result in high quality content which is very
valuable for the hiking guide and the touristic activities in the
Montafon area. In previous projects the contractors Schruns-Tschagguns
Tourismus and Stand Montafon as well as the coordinator telesis have
already much experience in the planning and production of content for
tourist applications. Consequently, the content implementation phase
can profit from this experience and a successful implementation of the
content concept and thus the feasibility of this part of the project
can be expected.
DEVELOPMENT RISKS
One
risk of the development is the unavailability of Galileo receivers:
Even though the mobile hiking guide system can rely on the GPS
receivers that can be bought on the market today an early availability
of prototypical receiver devices by ESA would be helpful for the mobile
system design and even minimize the project risk with regard to
location preciseness and reliability as described below. As the
existing GPS system also delivers position information, the system can
intermediary run on existing GPS receiver hardware. The only risk left
is that the demonstrator system can unfold its functionality only in
the ranges of the GPS preciseness and reliability. However, due to the
design on the application, a switch to the Galileo Hardware only means
adjustment of the drivers that actually access the receiver hardware on
the mobile device, which is a calculable effort.
Another risk of
the project is that even though a detailed storyboard and content
implementation plan has been developed, the content production may take
too long: The detailed elaboration of a storyboard before the content
production forms a means to determine the content that needs to
collected, produced, and preprocessed for the system. As the project
plan includes an early first prototype in the middle of the software
and content production phase this risk can be reduced as experiences
with the first demonstrator in the middle of the project allow for an
adjustment of the software development and content implementation
tasks. The coordinator telesis and the contractors Schruns-Tschagguns
Tourismus and Stand Montafon bring in the experience from previous
projects with regard to the content production for regional tourist
applications in the Montafon region. Also the partners bring in some
content for the project. Both the available geo data and tourist
information as well as previous experience in planning, collecting, and
maintaining tourist information reduce the risk of an unintended
exceeded of the content production effort.
Finally, the
software development process for the mobile hiking guide could take too
long or does not deliver the expected system functionality: Here the
existing know how of the previous prototypes is brought into the
project by the contractor OFFIS. The modules of the basic platform and
existing research prototypes give the project a good basis to be able
to quickly start to develop the mobile system for the specific
application and finish convincing demonstrators in time. The existing
prototypes of the contractor OFFIS show that the basic functionality
for map presentation, point of interest presentation, and localization
are well applicable such that a successful application on these basic
modules and their extension for the specific mobile hiking guide can be
expected. This much reduces the software development risk.
STUDY PLAN
This study plan is organized in working packages along the three project phases of consolidation, implementation, and technology transfer. Figure 2.3-1 shows a flow chart of the study plan. It shows the single tasks of the project and their interdependencies. The numbering of the tasks and the expected deliverables during the course of the project corresponds to the number given in the list of deliverables, the detailed work breakdown structure, and planning in Section 3.5, 3.6, and 3.7. The arrows in the study plan show which results of the single tasks are input to other tasks in the project course. The numbering of task is the same that is used in the work breakdown structure and project planning which are presented later in this tender. In the following the study plan for the proposed project is elaborated in detail along the project phases.
CONSOLIDATION
The
consolidation phase comprises one single task, the consolidation of the
project. During this task the proposal of the project is refined. This
includes a detailed refinement and consolidation of the project plan,
the work packages, and single tasks. For the demonstrator also a
demonstration plan is elaborated at the very beginning of the project
such that the content and software implementation can deliver their
results that are integrated into the demonstrator very targeted. The
driving force for the software development and demonstration project is
the application domain of tourism, in the consolidation phase also the
application requirements from the domain of tourism will be reviewed
and consolidated into a detailed elaboration of these application
requirements.
The results of the consolidation work package are
a refined work plan, detailed application requirements, and a
demonstration plan in the deliverable of Task 1.1 of Work package 1. As
Figure 1 illustrates, the results of this work package are input to the
implementation phase of the proposed project. In the following we
describe the study plan in detail.
IMPLEMENTATION PHASE
In
the implementation phase the software development of the mobile system
as well as the creation, editing, and processing of the content for the
mobile information systems in the application areas are developed. The
software development for this system and the demonstrator is to be
carried out in Work Package 2, the Software Implementation. The mobile
hiking guide presents location-based information to the hiking
tourists. This information is collected, produced, and elaborated in
the Content Implementation Work Package. These two work packages are
carried out in parallel with distinct matching between the two work
packages during the project.
SOFTWARE IMPLEMENTATION
The
development of location-based and context-aware multimodal system
platform for the mobile hiking tours is developed in Work Package 2.
The tasks of this work package realizes the software engineering
process following standard practices. An important objective of the
software implementation is to realize a demonstrator application that
shows the feasibility of new technological concepts and the potential
of the innovative concepts in the application domain.
Analysis and Design:
This
task comprises the analysis and design of the software system. Based on
the reviewed and refined application requirements and the demonstration
plan determined in a deliverable from the consolidation phase a
detailed software analysis is carried out. This includes “lower level”
requirements such as hardware requirements or network connection but
also requirement with regard to architecture and user interface. The
experience of the contractor OFFIS in the field of mobile systems and
platforms will support the design. This task will result in a detailed
specification of a modular system, the single modules and interfaces,
as well as the specification of the location-based context-aware
multimodal hiking guide application. The system design will provide for
the specification of modules that realizes the basic functionality
needed for the system: localization, map visualization, POI management
and visualization, profile management, context-aware content selection
and presentation, multimodal user interface. Here, the existing system
platform design of the contractor OFFIS forms the input to the analysis
and design task.
To keep the software implementation and the
content implementation “in line” one person from each contractor and
the coordinator meet after Tasks 2.1 and Task 2.2 to bring their
results together and synchronize their work before in Work package 2
and 3 the implementation of the first software implementation and the
content production start.
• First implementation: In this
task a first implementation of the mobile system is developed. Existing
modules are used and extended to meet the specific application
requirements. Challenges are the context-awareness of the system and
the task oriented multimodal user interface. For the implementation the
existing basic modules of the platform are employed and extended to
meet the application requirements and the system design. These modules
are a Location Module, a GIS Module, a POI Module, a Multimedia Module,
and Auditory Support Module. These modules provide basic functionality
for location-based mobile components; the specific requirements of
context-aware systems and multimodality for this specific application
are developed as new or extended modules. The development of the basic
functionality of the mobile guide application can then be achieved by
reusing existing components and newly developed components and
implementing the application specific tasks on top of these.
The
result of the first software implementation is input to the first
demonstrator in plan. In this demonstrator the content production and
the software implementation are integrated and tested for the first
time. This first demonstration will give substantial input to the
refinement of the software and content implementation.
•
Refined design & implementation: In this task the first design and
implementation is refined. One important input for this refinement is
the first demonstrator in place. Also the mid term meeting reviews the
first project results and gives directions for adjustments of design
and realization. This input and common practices in software
engineering in reviewing and refining a system architecture, modules,
and interfaces the first implementation is transformed into a stable
and refined software implementation. For the refined implementation
also sophisticated and enhanced functionality is added to the system
modules. Now, the full system and application functionality is
achieved. An important objective of the refined implementation is to
achieve an implementation of the innovative aspects of the mobile
application such that the demonstrator shows the feasibility of the new
and innovative concepts in the application domain.
The result of
the refined software implementation is input to the final demonstrator.
In this demonstrator the content production and the refined software
implementation are integrated and tested.
• Test and
finalization: In this task the different modules of the mobile system
are tested in detail and finalized. This task runs in parallel with the
final demonstrator. Finalized modules and functions from the software
development are transferred into the final demonstrator.
CONTENT IMPLEMENTATION
In
parallel to the analysis and design process in Task 3.1 the detailed
design of the content production is elaborated. An important objective
of the content implementation is the selection and production of
content that best illustrates the power and the potential of the
developed application.
• Detailed content design: Here a
storyboard for the trails and the points of interest are in the focus.
The storyboard will elaborate the a content production plan for the
trails, the collection of geo-referenced POIs, the collection of
additional tourist information and the integration of existing geo
data. Included in this work is the evaluation of the hiking route and
the selection of those routes that are applicable to the application.
In this task about 5 hiking tours with about 200 POIs are to be
recorded for the hiking guide applications. Along with the routes a
content structuring takes place in which a unified structure for the
trails and the POIs is defined. The storyboard defines the selected
routes and POIs, specifies which information is to be collected,
integrated and recorded and gives detailed instructions about the
collection, integration, recording, processing of the multimedia and
geo-reference material. In addition to the storyboard, a user interface
design is developed that meets the multimodality requirements of the
hiking tourist. With regard to the context-awareness the detailed
content design defines the context parameters that are relevant for the
hiking applications and determines a reasonable context-awareness in
the specific application context. As the content production is a time
consuming task the storyboard and the selected information needs to be
carefully determined.
To keep the software implementation and
the content implementation “in line” one person from each contractor
and the coordinator meet after Tasks 2.1 and Task 3.1 to bring their
results together and synchronize their work the implementation of the
first software implementation and the content production start (T 2.2,
T 3.1).
• Content Production: Following the detailed content
design and storyboard developed in the first task of the content
implementation the actual content collection and editing is carried
out. One specific effort is the collection and editing of the data for
the application and its preparation for the different user contexts as
for example language, age, and type of hiker. The local experts in the
field carry out this work. The experience of the work in this section
contributes to the dissemination of the project as the contractors from
the Montafon region intend to continue the work and transform the
system into a commercial product. Included is the multimedia content
preparation of images and audio, which is time consuming and therefore
limited according to the storyboard. With regard to the geo-reference
information, fortunately the Montafon region has a very rich
information base of hiking trails and spots of interest. Nevertheless,
the location-based information forms a substantial part of the work is
the recording of the POIs. For each of the POIs comprehensive
information has to be collected, recorded, and integrated. For the geo
referenced information and geo data the contractor Stand Montafon
brings in the expertise of the local player that is familiar with the
Montafon region. Again the targeted involvement of the participants
with the specialized expertise not only contributes to the project
success but also to the later dissemination of the project by these
contractors.
The result of the content production is input to
the final demonstrator. In this demonstrator the content production and
the refined software implementation are finally integrated and tested.
•
Content finalization and polishing: In this task the content is
finalized and polished. This means that the existing content and the
compliance with the storyboard are checked and final changes and
amendments to the content are made. This can include final edition and
processing of media, text, and geo data, fine tuning of the content
structures, organization of the digital media.
DEMONSTRATOR AND DISSEMINATION
A
demonstrator and test evaluates concrete instances of the mobile
system. Following good standards in software development process the
project flow is set out such that an early prototype and demonstrator
test gives feedback for the refinement of the specification and the
implementation of the system. The central results of the project is a
validated demonstrator that shows the innovation and the potential for
tomorrow’s mobile tourist information systems. The demonstrator is
ready to be transferred into the commercial tourism activities of the
participating European regions.
• The first demonstrator:
shows and applies first project results at an early stage in the
project to confirm the feasibility of the project’s objectives and to
achieve substantial input for the refinement of content and software.
The first demonstrator is stimulating the second phase of the project,
which leads to the final demonstrator.
• The final
demonstrator and dissemination: integrates the final software system
and final content. He forms the central goal of the project, the
realization of a location-based context-aware multimodal hiking guide
for tourists in the Montafon area. The demonstrator shows the proof of
concepts that forms the basis for the technology transfer into the
Montafon region as a commercial product for hiking tourists of the
area. The final demonstrator forms an attractive application prototype
that unfolds the innovative concepts and the potential for the
establishing such a system in Montafon region. The final prototype will
be presented in public information events in the Montafon area to raise
interest in the system and the commercial potential for the touristic
development in the Montafon region. Additionally, introduction of
interested persons from the application domain into the system
installation, demonstration, and evaluation allows for a broader
visibility of the system and increases the potential of a transfer of
the system into a product of the Montafon tourism activities.
TECHNOLOGY DEVELOPMENT OR RESEARCH AREA
The
tender is placed in the area of mobile multimodal information systems.
The technological development undertaken in this project are addressing
mobile platform development, context-awareness, location-based
information, multimodal user interfaces, positioning, and content
personalization. From a content development aspect this tender proposes
the integration of local tourist information and infrastructures with
innovative mobile technology.
METHOD FOR TECHNOLOGY TRANSFER AND ADDRESSED USER GROUP
The
developed mobile hiking guide bases on the mobile platform developed by
the project partner OFFIS in the context of research and development
projects. In these projects OFFIS has elaborated and implemented a
modular platform for the development of mobile applications. In the
proposed software development and demonstration project this platform
is applied in for tourism, specifically hiking, and elaborated and
extended according to the specific application requirement.
Consequently, the location-based mobile hiking guide application is
transferred into a demonstrator application which can be continued into
a commercial product of the regional project partners in the Montafon
area in Austria. In the dissemination phase installation and
demonstration guides are developed which can contribute to a
dissemination and multiplication of the installed demonstrators. During
the content production and demonstration phases the key personal of the
contractors from Stand Montafon and Schrunz-Schagguns gain experience
which helps after the project and to elaborate and extend the
demonstrator of the hiking guide application. By this the possibility
of a continuous and successful transfer into a commercial product in
the Montafon tourist program is strongly increased.
The intended
user groups are everyday tourists that visit the region. The Montafon
region has about 250.000 guest per season. After the dissemination
phase of the project the Schrunz-Schagguns Tourismus will carefully and
continuously to selected tourists to gain experiences with the
acceptance of the system. At the same time the contractors from the
Montafon region will employ the demonstrator for the acquisition of
additional commercial partners for a stable implementation of the
system in the region.
