Device and method for character or command input controlled by teeth

Abstract

The invention relates to a device and method for character or command input controlled by teeth. The device comprises a collecting module for collecting brain electromyographic signals of tooth action states, a wireless sending module, a wireless receiving module, a signal processing module and a character or command input displaying module. According to the device and method for character or command input controlled by the teeth, the brain electromyographic signals produced by the tooth action states are collected, data processing is conducted on the collected signals, and the signals are converted into control commands. Due to the fact that tooth control is convenient, simple, comfortable, quite, real-time, accurate, and free of interference (free of influence of speech of a user or external speech, and free of influence of body actions of the user), has multiple tasks, has no damage, does not cause distraction of the user, is suitable for most people and the like, tooth input can be used as effective supplement and replacement of manual input and speech input.

Description

technical field [0001] The invention belongs to the field of cognition and intelligent computing, in particular to the field of human-computer interaction, and specifically refers to a device and method for inputting characters or commands using electroencephalogram signals generated by tooth movements. Background technique [0002] Currently, in the known field of human-computer interaction, human-computer interaction input methods include manual input (including hand and foot movements), voice input, and idea input. The manual input method is the mainstream, widely used and mature; the voice input method is also constantly developing and improving; the idea input method is still in the initial stage of transformation from laboratory research to practical use. [0003] As is known, manual input methods are very mature, such as smart phones that widely use manual touch screen input methods, but in situations such as hands and feet being occupied by control tasks or han...

AI Technical Summary

Problems solved by technology

At present, the idea input method, or the recognition action state is single and the accuracy is not high (such as motor imagery), or the accuracy is high and the recognition time is long (such as P300, that is, the brain wave signal is strengthened after 300 milliseconds of visual stimulation)

In addition to the manual input method, the voice and idea input methods cannot realize multiple states, reliable and real-time control in key occasions
