[0053] Example

[0054] Such as image 3 As shown, the device of the present invention is mainly divided into two parts: the first part is a main controller with a keyboard, a microphone and an LCD display screen, and the second part is a set of (6) wireless devices attached to different parts of the body of the hearing impaired. Vibration patch. The main controller is used to encode the voice input signal or keyboard input signal in Braille Shuangpin, and send the encoded 6-bit binary code information sequence to the target vibrating patch via the ZigBee wireless network. The vibrating patch receives the information sequence sent by the main controller, and converts it into a control signal for the vibrator, so that the vibrator vibrates according to the information sequence. The hearing impaired understands the meaning of the message by sensing the vibration of each patch.

[0055] Such as Figure 4 As shown, the main controller includes: a processor, a voice signal processing ...

Abstract

The invention discloses a communication method and device for hearing-impaired people based on Braille coding and vibration perception. The device comprises more groups of wireless vibration chips and a master controller with keyboard input, voice input and display functions. In the method, the master controller is used to code voice input or keyboard input information, and the coded information sequence is sent to the vibration chips which are adhered to the different parts on the bodies of the hearing-impaired people by ZigBee wireless network; and the vibration chips vibrate in accordance with the received information sequence, so that the hearing-impaired people can master the sent information by perceiving the vibrations of the different chips, thus realizing the wireless communication between an information-sender and the hearing-impaired people. According to the invention, the communication is realized by perceiving multi-point vibration, thus being convenient to use and carry, and ensuring to receive urgent messages in time.

Description

technical field [0001] The invention relates to the technical field of wireless communication for hearing-impaired persons. In particular, it relates to a communication method and device for hearing-impaired persons based on Braille coding and vibration perception. technical background [0002] According to statistics, the total number of disabled people in my country is about 100 million, and hearing-impaired people account for about one-third of the total number of disabled people. As vulnerable groups, they need help in many aspects of their daily lives. Although there are special communication methods such as sign language and lip language, and auxiliary instruments such as hearing aids, these communication methods and instruments still cannot effectively help the hearing-impaired to solve hearing problems in many cases, such as watching TV programs without subtitles, using the radio, Call and wait. [0003] At present, the management system and auxiliary facilities of...
