摘要

Shoes for blind man help or assist optically handicapped person to reach their respective terminus. It presents a working conceptual model a concept to provide a clever automated wearable device for blind people. The structure is proposed to offer overall solutions which include artificial vision and object detection. Ultrasonic sensors help in calculating distance of the hurdles lying in the path of blind person. This device help in providing best available track to the user in the form of audio. The sensors are integrated with the shoe so that the blind person can not only detect obstacles in front but also detect the presence of any major pits on the way. Also it contains a panic button which can send SMS alerts in the case of emergency. The hardware consists of Arduino Lilypad based embedded system, ultrasonic sensors, IR sensor, GSM modem, Audio playback board with speaker/headphone. The voice output is generated by an Audio Processor using APR9600 module which can store, record and playback 8 different messages. These messages can be modified according to the user's convenience and language preference.
