Abstract

This thesis 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; 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) was performed to illustrate the efficacy of the R-MAP. Improved feedback and new functions were added to ease the use of R-MAP.
