SIGNAL TRANSFORMATION METHOD AND GUIDANCE SYSTEM PROVIDING AUDITORY AND TACTILE INDOOR/OUTDOOR TRAVELING INFORMATION FOR THE BLIND

摘要

The present invention relates to a portable walking guidance method and apparatus for transmitting an audible or tactile sense of obstacle information and global position information required for walking of an visually impaired person using an ultrasonic sensor and a GPS.;In the present invention, the comprehensive information of the user's gaze direction, walking direction and left and right direction obstacles obtained from glasses with two ultrasonic sensors and a cart with four ultrasonic sensors is provided. It transmits by vibration through a small motor, it is characterized in that the location information for the user to reach the destination from the GPS (user's current location, distance to the destination, direction information to go to the destination, etc.) and the like voice.;Therefore, the present invention provides the location information necessary for the visually impaired to reach a desired destination, and the distance and direction information on obstacles in the walking direction and the gaze direction during walking, thereby providing an effect of safely reaching the desired destination.;Blind Guidance System, Portable Walking Guidance Device, Ultrasonic Sensor, GPS, Speech Synthesis, Acoustic Cognitive Training, Destination Guidance Device, Obstacle Detection
