Abstract

This paper describes the development of an electronic device that aids blind people in identifying objects, which by their nature are challenging to do by touch or other senses. The device created can associate voice messages with objects and indicate the time audibly. The prototype is composed of a dsPIC30F4013 that is responsible for all digital signal processing operations and system control, an RFID reader/writer module to identify tags attached to objects, a voice CODEC for A conversions /D and D/A, an SD memory to store digitized voice messages and the DS1307 real-time clock integrated circuit.
