Red Angel / a GPRS intelligent guide

This is a GPRS pathfinding terminus that can be used in the emergent situation for the blind. It is fit for both outside and inside door.
When an emergency is happening, the screen of the guide will be changing. There is going to appear a map that can lead the blind to run away. Then can get to know the shape of the map by touching the screen. At the same time, a voice will come up as a hint.
When there is an emergency happening, the intelligent guide will automatically send a message by GPRS for help.
In the daily life, the intelligent guide can help owners adapt themselves to a new environment.
