Abstract—Design of ubiquitous technology for providing an unobtrusive environment for day to day routine activities for physically challenged people is a challenging issue. More reliable system with accurate information dissemination depending on the context location is important in the design of such systems. In this work we have proposed a model using mobile location based information dissemination for physically challenged persons (hearing/visually impaired persons). An audio/video assistance application is developed, that provides the directional information vector at any instant on the handheld device. The contextual information is obtained from the connectivity, orientation of device, person’s impairment, time, location, etc. The prototype implementations are carried out at our research lab, using recently released Internet mobile phone/tablet (N810, N900), and using open source Maemo platform. Suitable GUI is developed for voice / video information dissemination. Applications are developed by mapping our institution layout to access point position and orientation of the mobile device.
