Research and implementation of blind reader system based on android platform

The blind can only get perceptive and audio information. Mobile devices could provide the blind great help. This project deals with a new android-based blind reader system designed for the blind to get photocopy information. However, it is difficult for the blind to locate and select items visualized using touchscreen. So this paper presents non-visual interaction which combines auditory interface with multi-gesture operation. In addition, considering the blind usually cannot get complete and effective text area when shooting photocopy text, this paper adopts the image projection method to determine text boundary and uses voice command to prompt moving direction. The experiments are performed separately under noisy circumstance and quiet circumstance. The results show that the starting use of the system can lead to some misuse but blind users can get photocopy information smoothly by the system after some training. It indicates a need for further development of this concept.
