Description
Technical Field
[0001] The utility model relates to the technical field of the blind, in particular to a wearable bracelet for the blind. Background Art
[0002] In order to improve the quality of life of the blind and help them walk safely, many countries around the world have researched and designed many guide products, such as electronic blind aids, blind binaural voice prompt systems, electronic blind aids, etc. Most of the blind people choose electronic guide sticks, but from a functional point of view, the current electronic guide sticks have defects such as short detection distance and inability to alarm. In addition, because the product has a strong symbolic effect, it is easy for pedestrians to recognize it as a blind person. Therefore, most blind people do not use the sticks very much because of their self-esteem. In modern society, there are bracelet products for the blind.
[0003] The obstacle avoidance bracelet for the blind is an auxiliary product for the blind to avoid obstacles. When the blind wear the bracelet and encounter obstacles, the bracelet will remind the blind that there are obstacles around them to prevent the blind from hitting the obstacles, which brings great convenience to the blind walking;
[0004] The existing obstacle avoidance bracelets for the blind generally only identify obstacles to ensure the safety of the blind. However, when the light around the blind is dim, it is difficult for pedestrians on the road to observe the blind and they are prone to bump into the blind. The safety of the blind still has hidden dangers. A wearable bracelet for the blind is needed to solve the above technical solution. Utility Model Content
