Abstract:

This paper proposed a tactile display system of mechanical dot matrix for the blind's electronic reading. The statuses of dots were kept by claws latching the different positions of the display pins, and the raise status of display pins were controlled by one Z axis actuator cooperating with XY mobile stage. Then all the display pins would be reset by the reset actuator, so that the statuses of dots might be interchanged automatically. The experimental results show that 54 dots can be automatically interchanged in 1 minute between upward and downward positions by using a Z axis actuator.
