In this paper, the authors design device to help the blind people to navigate the environment without asking anyone. The device based on GPS (Global Positioning System), the raw data for location coordinate where the blind people stands is detect by GPS receiver, processing these data by PIC microcontroller to calculate real coordinate related with current position, then translate it to specific voice message which are presorted in voice recorder, the blind person hears voice message through the headset. Their design aims are to produce device that is more cheap by using little number of components and easy to use so that the blind person not need to do any thing just hearing the voice message.
