Abstract

The invention discloses a Doppler effect-based blind person directional training device and method for simulating outdoor danger avoidance, and relates to the technical field of blind person directional training. The Doppler effect-based blind person directional training device for simulating outdoor danger avoidance comprises a bottom plate and is characterized in that two fixing plates are fixedly connected to the middle of the top of the bottom plate, the opposite sides of the two fixing plates are movably connected with the left end and the right end of a roller respectively, the roller issleeved with a belt, a supporting plate is arranged in front of the belt, and the bottom of the supporting plate is fixedly connected with the top of the bottom plate. According to the Doppler effect-based blind person directional training device for simulating outdoor danger avoidance, a training simulation mechanism is arranged, and a second rotating motor, a horizontal rotating rod and a connecting rod are arranged in a matched mode, so that the perception sensitivity of a blind person to surrounding sounds is effectively enhanced based on the Doppler effect, and the avoidance reaction force of the blind person to outdoor danger is improved.

Description

[0001] This application is a divisional application with the application date of June 21, 2018, and the application number CN20181064519.5. The title of the invention is an orientation training device for the blind based on Doppler effect simulation of outdoor danger avoidance. technical field [0002] The invention relates to the technical field of orientation training for the blind, in particular to a device and method for orientation training for the blind based on Doppler effect simulation of outdoor danger avoidance. Background technique [0003] When a blind person walks outdoors, the brain can establish a temporary neural connection between the sound and specific things by locating and locating the sound source based on the difference in the intensity of the sound reaching the two ears and the difference in the time when the sound reaches the two ears, and the individual can learn through hearing. orientation. [0004] According to the principle of the Doppler effect,...
