This paper is concerned with the development of the wearable sensor system for reading 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, a robust recognition 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. For the improvement of the performance, the classification is carried out using plural classifiers, each of which is based on multi-layer perceptions. The multi-layer perceptions are used in the form of dichotomizers, each solving a two-class classification problem. 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.
