[Recognition of Chinese character on electrotactile vision substitution system]

In this paper, we used the eletrotactile vision substitution system designed by ourselves to display Chinese characters on the 16x16 electrode array through some simple image processing algorithms and multiplexing technology. Based on this, simple Chinese character recognition experiment was conducted. The result of the experiment shows that the electrotactile vision substitution is a feasible solution for the blind to read simple Chinese characters and the result also solidifies the foundation of further study about more complex real-time image electrotactile display.
