Abstracts: With the development of social affairs and human civilization, the services demand for the Blind and handicap people has been increased, as well as for the development of better means of service. This paper outlines a design which incorporates the power of concurrent GPS and GSM networks positioning technology to provide location-based services for a blind stick. It offers a better monitor service for the person who is a blind or a handicap. In contrast to methods which depend solely on GPS positioning, the proposed method provides higher positioning accuracy and is capable to compensate the problem of the loss of GPS signals in urban areas or indoors. The design is composed by a GPS receiver, a GSM/GPRS module for location acquisition and message transmission, a 32-bit AVR controller and a web-based management server designed on the Lab Windows/CVI for monitoring and tracking the blinds tick positions. We have implemented several real world experiments for our design and results are promising. As well as water, fire, distance measurement sensors use for daily usage.
