摘要：
This paper reports a wearable and wireless system for Braille recognition, called TouchReader, which utilizes a fast and accessible strategy to facilitate visually impaired people in learning and communication. This finger-worn device is composed of flexible and piezoresistive sensor array with high density (96 sensors in 78.5 mm(2)), high sensitivity (8.44 kPa(-1) in low pressure range) and a template-matching recognition system. It is the first time to achieve area-scanning of Braille character on the strength of tactile sensors and convert text to voice message, exhibiting better practicability, portability and reliability in daily routine with less manual intervention.
