Background
Map type information tends to beembedded into more and moreapplications 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
Problems arise when:
• You are not able to use your hands /(or fingers precisely)
• Your are partially sighted or blind
• You are an elderly person
Background
www.haptimap.org
Some existing solutions: Non-visual channels
But: Often used as enhancement of the visual
• Multimodal perceptualizations improve the accesibility andusability of mobile navigation applications
Background
www.haptimap.org
To know user opinions and experiences about habits in routes
To detect user´s needs regarding assistive solutions for navigation
Goal
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
User requirements
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,..)
User studies: iterative and user-centred designmethodology
User requirements
Visually impaired people:
• Flexible system/interfaces to adapt to individualneeds/preferences/expertise
• Pervasive but not disturbing
• Taking into account temporary obstacles in the route
• High accuracy of the maps and reliability of the positioningsignal
• Multimodal interfaces
User requirements
www.haptimap.org
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
Proposed solution
What info is taken
into account?
Capacity of
data input
Capacity of
data output
Capapacities of
communication
and location
How to obtain
the info?XML documents published
by the device when
connecting to platform
Proposed solution
partially sighted
wheelchair user
Accept
Maintenance works
for gas installation
in Main Avenue,
during weekdays.
Profiling
Accept
Street works
in Main
Avenue. Not
suitable for
wheelchairs.
Adapted InformationOriginal Information
User Profile:
Adaptation of contents: example
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.
Proposed solution

Development of non-visual interaction channels: easier to use andalso more accessible to a wide range of users, integrating HW as:
haptic devices
vibration devices
hearing aids
