摘　　要：为了研究视觉假体佩戴者完成拼图任务时所需时间与原始图像复杂度、被试性别、光幻视的分辨率以及是否能够识别实验图片之间的关系,借助计算机编程技术,将仿真假体视觉下的拼图任务呈现给视力正常的被试者,并在实验过程中调整实验图片的复杂度(分为简单,中等,复杂三组)和不同的仿真光幻视的分辨率(16×16,24×24,32×32,48×48,64×64,128×128六个分辨率)等参数。实验结果表明,中等难度组的实验用时最多,从简单组到中等难度组识别时间有增长的趋势,从中等难度组到复杂组,识别时间有减少的趋势。男性的平均识别情况好于女性,且随着分辨率的增加,用时整体呈现减少的趋势。In order to study the relationships among the needing time when the visual prosthesis wearer conducts jigsawtask,original image complexity,gender of the tested staff and resolution of pseudopsy,and whether experiment images can berecognized,the jigsaw task in visual prosthesis simulation is presented to the testee with normal eyesight by means of computerprogramming technique.The parameters are adjusted in the experiment process,including the low,medium and high complexi?ties of the experiment images and resolutions(16×16,24×24,32×32,48×48,64×64,128×128)of the simulated pseudopsy.The experimental results show that the experiment with medium complexity consumes the longest time;the recognition time fromthe low complexity to medium complexity presents the trend of increase;the recognition time from the medium complexity tohigh complexity presents the trend of decrease;the average recognition effect for male is better than that for female;the wholetime consumption appears the trend of decrease while the resolution is increasing.
