The document discusses the HAPTIMAP project, which aims to make location-based services and mobile devices more accessible to dependent users. It outlines the problems that arise when maps are embedded in mobile applications with small screens that require visual attention and both hands. The project conducted user studies with elderly and visually impaired people to identify their navigation needs. Based on these requirements, the proposed solution is a software platform that adapts user interfaces and location-based information to individual users' profiles and disabilities. This includes personalized routing, public transportation assistance, and non-visual interaction channels like haptic devices.

- 1. “Making location based services and mobile devices accesible to dependant people: the HAPTIMAP project ” Arantxa Renteria, Alfonso Dominguez Dept. of Health & Quality of Life, TECNALIA 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. Accept Accept
- 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 www.haptimap.org
