2b7 making location based services

  1. 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. 2. BackgroundMap 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
  3. 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. 4. BackgroundSome existing solutions: Non-visual channelsBut: Often used as enhancement of the visual • Multimodal perceptualizations improve the accesibility and usability of mobile navigation applications www.haptimap.org
  5. 5. GoalTo know user opinions and experiences about habits in routesTo detect user´s needs regarding assistive solutions for navigation www.haptimap.org
  6. 6. User requirementsAnalysis 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. 7. User requirementsUser studies: iterative and user-centred designmethodologyRequirements 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. 8. User requirementsVisually 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. 9. Proposed solutionIntegrating requirements and LBS: Development of software to adapt the user interface to theneeds 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 servicesAdaptation of contents to: - specific mobile device resources and, - user needs www.haptimap.org
  10. 10. Proposed solution Capacity of data inputWhat info is taken Capacity of into account? data output Capapacities of communication and locationHow to obtain XML documents published the info? by the device when connecting to platform
  11. 11. Proposed solutionAdaptation 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. 12. Proposed solutionApplications:• Generation of user’s content. Users create their own content using theirmobile 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 publictransportation.• Navigation. This service allows users to explore their surroundings.• Location of people. Helping careers find patients, and for visually impairedpeople.
  13. 13. Proposed solutionDevelopment of non-visual interaction channels: easier to use andalso more accessible to a wide range of users, integrating HW as: haptic hearing aids devices vibration devices www.haptimap.org
