This paper introduces the basic concept of man-machine interaction technique and the pathological and physiology basis of its application in guiding equipment. Based on the analysis of demands of blind people, the design for novel intelligent guiding equipment based on man-machine interaction technique was proposed. This method used multiple sense information mainly by infrared technique to detect obstruction and control the advancing direction of whole guiding equipment through the intellectualized judgment and processing by microprocessor to guide the blind. In addition, the principle and process of detecting method, control function, command definition, program design and debugging improvement of the guiding equipment were introduced, and its application and prospect were discussed.%介绍了人机交互技术的皋奉概念和将其应用于导盲装置设计中的病理生理学依据.通过分析盲人的切身需求,提出了一种基于人机交互技术的新掣智能导盲装置的设计思路,即应用以红外传感技术为丰的多化感器信息融合来进行障碍物探测的,并通过微处理器对探测结果:的智能化判断和处理,实现对整个装置行进方向的控制,进而达到引导盲人的作用.文章还阐述了该导盲装置的探测方式、控制功能、指令定义、程序设计和调式改进方面的原理和过程,并展望了其心用和发展前景.
