Design of Infrared Detecting Intelligent Guiding Equipment Based on Man-machine Interaction

This article has introduced the basic concept of man-machine interaction technique and the pathological and physiology basis which the man-machine interaction technique applies to the guiding equipment.Through analysing the true requirement of the blind and comparing with the advantages and disadvantages of the common types of guiding equipment,the designing theory about a new type of intelligent guiding equipment based on man-machine interaction technique was showed.This method used multi-sense information mixing mainly by infrared technique for detecting obstacle,realizing the control to the advancing direction of the whole guiding equip- ment and the blind through the intellectualized judge and process by microprocessor.This paper discussed the principles and course of detecting method,control function,order defined,design progress and mode improvement.The infrared detecting intelligent guiding equipment based on man-machine interaction was triumphantly made to communicate with the blind by obtaining the signal of obstacles and receiving commands.The practical test is successful by programming,which shows that the scheme is viable and possible to develop applied products in terms of the theory.The future of application and development about this guiding equipment was predicted finally.
