Abstract
This paper is concerned with the development of the wearable sensor system for recognizing Braille. A compact wearable sensor using a PVDF (Polyvinylidene Fluoride) film is developed. The sensor output is measured with the sensor mounted onto a fingertip moving over Braille manually. A compact measurement part, a robust recognition part and a voice output part are also proposed. The wearable sensor system is fabricated by combining the sensor with these parts in order to teach the user the recognition results by real-time voice output. The sensor system is examined experimentally whether it is effective to recognize Braille. The obtained results show that the wearable sensor system is effective to recognize Braille.
