We have developed some building-block technologies required for realizing wearable vision assistive devices that automatically detect text on paper documents, signboards, etc. in the environment, translate it into speech by Optical Character Recognition and Speech Synthesis, and present the contents to the visually-impaired users. The technologies include fast and precise automatic text region detection and tracking, fast pattern matching for real-time character recognition, and text location guidance using sound signals. We have also developed a prototype system, and obtained the knowledge about the usability and functions need to be improved.
