This PowerPoint helps students to consider the concept of infinity.
2b7 making location based services
1. “Making location based services and mobile
devices accesible to dependant people:
the HAPTIMAP project ”

www.haptimap.org
2. Background
Map type information tends to be
embedded into more and more
applications on mobile devices >>>>>>
• Smaller screens
• Smaller buttons
• You may need both hands to operate
• You need to pay visual attention to the
screen
www.haptimap.org
3. Background
• You are not able to use your hands /
(or fingers precisely)
Problems arise when:
• Your are partially sighted or blind
• You are an elderly person
www.haptimap.org
4. Background
Some existing solutions: Non-visual channels
But: Often used as enhancement of the visual
• Multimodal perceptualizations improve the accesibility and
usability of mobile navigation applications
www.haptimap.org
5. Goal
To know user opinions and experiences about habits in routes
To detect user´s needs regarding assistive solutions for navigation
www.haptimap.org
6. User requirements
Analysis focused on:
• Elderly people
• Visually impaired people
Different approach (due to age and level of expertise):
•Elderly people:
•Sighted but with some visual impairments.
•Living independently or in a nursing home.
•Method: personal interview
•Visually impaired people:
• Total or partially blind
• More experience in using navigation devices
• Method: questionnaire with open-ended questions
7. User requirements
User studies: iterative and user-centred design
methodology
Requirements of elderly people:
• “Intelligent navigation”: avoiding long and steep walks
• Need of auxiliary auditory information
• Easier way to access the interfaces (button size, menu layout,..)
8. User requirements
Visually impaired people:
• Flexible system/interfaces to adapt to individual
needs/preferences/expertise
• Pervasive but not disturbing
• Taking into account temporary obstacles in the route
• High accuracy of the maps and reliability of the positioning
signal
• Multimodal interfaces
9. Proposed solution
Integrating requirements and LBS:
Development of software to adapt the user interface to the
needs of disabled people.
Multi-platform tools to support applications developers
Management of the user profile and special needs
Reception of info coming from location based services
Adaptation of contents to:
- specific mobile device resources and,
- user needs
www.haptimap.org
10. Proposed solution
Capacity of
data input
What info is taken Capacity of
into account? data output
Capapacities of
communication
and location
How to obtain XML documents published
the info? by the device when
connecting to platform
11. Proposed solution
Adaptation of contents: example
User Profile: partially sighted
wheelchair user
Original Information Adapted Information
Profiling
Maintenance works Street works
for gas installation in Main
in Main Avenue,
during weekdays. Avenue. Not
suitable for
wheelchairs.

12. Proposed solution
Applications:
• Generation of user’s content. Users create their own content using their
mobile devices, annotating, uploading and sharing it with the community.
• Personalized routes. The route will take into account possible disabilities.
• Public transportation. This service focuses on helping users to move on public
transportation.
• Navigation. This service allows users to explore their surroundings.
• Location of people. Helping careers find patients, and for visually impaired
people.
13. Proposed solution
Development of non-visual interaction channels: easier to use and
also more accessible to a wide range of users, integrating HW as:
haptic hearing aids
devices
vibration
devices
