Abstract
This paper introduced basic concept of man-machine interaction and multi-sensor technique, and the medical theory, such as pathology and physiology, basis of its application in guiding equipment. Based on the analysis of demands of blind people and comparing the strong point and shortcoming among the common types of the guiding equipment, the design for novel intelligent guiding equipment based on man-machine interaction and multi-sensor technique was proposed. This method used multiple sense information mainly by infrared sensor and impacted sensor etc 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. The practice proves the application of this intelligent guiding equipment can deal with various requirements, and the prospect of it was discussed finally.
