Abstract :
Two simulated phosphene models were proposed in this paper. Model I was based on uniform or Gaussian round or square spots which arranged in rectangle or hexagonal arrays. Model II was based on partial clinical experiment data of one optic nerve prosthesis research. Numbers, letters and Chinese characters were pixelated by these models. The feasibility of using Model II to perform simulation experiments was discussed and confirmed.
