摘要/Abstract

摘要：

针对客观世界的场景图像复杂，与视觉假体有限的微电极刺激阵列之间的矛盾，从视觉信息需求入手，开展了视觉假体装置建模与视觉信息的研究，设计了视觉假体装置眼动机构的生物、机械、电子一体化模型，并通过心理物理学实验进行评估验证.实验结果反映了视觉假体使用者的视觉效果和最小视觉信息需求.

关键词: 视觉假体, 神经刺激器, 心理物理学

Abstract:

The conflict between the complex scene images of objective world and a limited array of micro-motor stimulation is a problem for visual prosthesis. Starting from the needs of visual information a visual prosthetic device modeling and visual information research was conducted. The visual prosthetic eye movement device was as a biological, mechanical, electronic integrated model, and the psychophysical experiment was conducted to assess the work. The results reflect the visual effects and minimum visual information needs.

Key words: visual prosthesis, neuro-stimulus chip, psychophysics
