Ultrasonic blind guide gloves

Abstract

The invention relates to seeing-eye instruments. An ultrasonic seeing-eye glove comprises a glove body and a seeing-eye device, wherein the seeing-eye device comprises a detection module, a feedback warning module and a signal processing module, the detection module and the feedback warning module are connected with the signal processing module, the feedback warning module carries out feedback through shakes, and the feedback warning module and the detection module are fixed to the glove body. According to the ultrasonic seeing-eye glove, due to the fact that the feedback warning module is fixed to the glove body, the hands of a user are freed. Meanwhile, due to the fact that the feedback warning module carries out feedback through the shakes, the tactile sense of a visual-impaired person can be made full use of to sense the environment, and the defects of a voice seeing-eye device are overcome. Furthermore, due to the fact that the hand is sleeved with the glove body when the ultrasonic seeing-eye glove is used, the detection direction can be determined through the swing direction of the hand, and the defect that the direction of a tactile stick is single is overcome.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to blind-guiding devices. Background technique [0002] There are following disadvantages in the existing blind guiding apparatus. Such as blind guide sticks, because they are inconvenient to carry and have a single direction, they can only detect whether there is an obstacle at a fixed angle in front of them, which affects the appearance and easily causes the inferiority complex of the visually impaired. Voice blind guides are expensive. When the ambient noise is stronger than the prompt audio, the visually impaired cannot obtain information from the guide; when the ambient noise is shielded, the visually impaired can only rely on the guide to obtain information. Sudden changes are prone to danger. Infrared blind guides are susceptible to environmental interference, signal distortion, resulting in misjudgment and accidents. Similar to blind guides that use tactile sensation to exp...

AI Technical Summary

Problems solved by technology

For example, the guide stick, because it is inconvenient to carry and has a single direction, it can only detect whether there is an obstacle at a fixed angle in front of it, and it affects the appearance, and it is easy to cause inferiority complex for the visually impaired.

Voice blind guides are expensive. When the ambient noise is stronger than the prompt audio, the visually impaired cannot obtain information from the guide; when the ambient noise is shielded, the visually impaired can only rely on the guide to obtain information. Sudden change, prone to danger

Infrared blind guides are susceptible to environmental interference, signal distortion, resulting in misjudgment and accidents

Similar to blind guides that use tactile sensation to express distance, there is often the problem that the difference in distance gradient is not obvious
