摘　　要：振动式盲人景物辨知仪利用电磁振动器的相对振动强度或频率表示颜色,利用电磁振动器的绝对振动强度或频率表示亮度,再结合使用者对扫描顺序的记忆特点,实现景物信息的振动表示。让盲人使用该实验电路,可通过感知振动而感知亮度和颜色,实现一定程度地辨知景物。Scene recognizing vibrator for the blind uses relative vibration of the vibrator to represent color,and absolute vibration to represent the lightness.Combined with the memory characteristic of the user,recognizing the scene by feeling the vibration could be realized.Circuits in this experiment which help the blind recognize the scene by feeling the vibrations controlled both by the brightness and the color of scene could help the blind distinguish the scene to some extent.
