The invention discloses a vibration touch feeling expression device capable of sensing the navigation information of a blind person. The vibration touch feeling expression device capable of sensing the navigation information of the blind person comprises an M*N motor array, wherein the M*N motor array is arranged on a waistband and is arranged at the front portion of the waistband when the waistband is worn by the person, M=1-3, and N=2-8. The vibration touch feeling expression device capable of sensing the navigation information of the blind person is characterized in that each vibration motor of the M*N motor array is connected with a motor driving circuit, and each motor driving circuit comprises an isolation module and a driving module. The vibration touch feeling expression device further comprises a master-control CPU module, wherein the master-control CPU module selects to switch on the motor driving circuits according to a motor control command acquired from a wireless communication module and control the corresponding vibration motors to work, and the motor control command comprises a vibration motor serial number, vibration amplitude and vibration lasting time. The vibration touch feeling expression device capable of sensing the navigation information of the blind person guarantees the walking safety of the blind person.
Description
technical field [0001] The invention relates to a vibrating and tactile expressing device for blind people's navigation information perception. Background technique [0002] At present, in order to improve the quality of life of the blind, researchers from various countries are committed to developing various blind navigation devices to help the blind overcome the walking obstacles caused by the lack of vision. Although there are crutches, guide dogs and other tools to help the blind walk, but very Difficult to assist them to walk in noisy environment. How to make blind people walk safely in noisy environments is a difficult point that researchers need to overcome. [0003] With the development of tactile perception theory and reproduction technology, the application of tactile prompts in navigation systems for the blind has attracted more and more attention from researchers from all over the world. Compared with the past relying solely on voice prompts for blind navigatio...
