用于盲人的图像振动触觉显示系统设计
Design of image vibrotactile display system for the blind
摘要
Abstract
In order to help the visually impaired perceive images with vibrotactile device, a tactile image display system is designed. It consists of a camera and an 8 × 8 tactor array based on an embedded system. In this system, the image is acquired from the camera, and then a 2-D image outline is captured. And the tactor array is automatically numbered into a linked list, producing dynamic vibrotactile stimuli, through which users can perceive image outline. The experimental results show that the vibrotactile display system has advantages in timeliness and portability. The dynamic vibrating coding is consistent with human tactile perception characters. Using this device, subjects with close contours can be identified more effectively.关键词
