摘要:
为了帮助视觉障碍者以振动触觉方式感知图像信息,设计了一个能自动采集图像信息并将图像轮廓转换为振动触觉刺激的触觉显示系统.该系统主要由摄像头和基于嵌入式系统的8×8振动触觉刺激阵列组成.系统能通过摄像头采集图片信息,提取物体二维轮廓特征,并以顺时针链表形式依次触发振动电机,产生动态振动触觉刺激,让佩戴者通过触觉刺激感知图像中物体轮廓特征.实验表明,该原理样机系统具有实时性好、携带方便的优点.动态振动触觉编码的方法符合人的触觉感知特性,对封闭轮廓物体形状的触觉提示识别率较高.
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.
