This paper presents the design, development and performance evaluation of a Reconfigured Mobile Android Phone (R-MAP) designed and implemented to facilitate day-to-day activities for people who are blind or visually impaired. Some of these activities include but are not limited to: reading envelopes, letters, medicine bottles, food containers in refrigerators; as well as, following a route plan, shopping and browsing, walking straight and avoiding collisions, crossing traffic intersections, finding references in an open space, etc. The key objectives were to develop solutions that are light weight, low cost, un-tethered and have an intuitive and easy to use interface that can be reconfigured to perform a large number of tasks. The Android architecture was used to integrate the cell phone camera, image capturing and analysis routines, on-device implementation of robust and efficient optical character recognition (OCR) engine and text to speech (TTS) engine to develop the proposed application in real-time. Empirical analysis under various environments (such as indoor, outdoor, complex background, different surfaces, and different orientations) and usability studies were performed to illustrate the efficacy of the R-MAP. Improved feedback and new functions were added based on usability study results.
