Wireless keyboard input method and device based on surface electromyographic signal recognition

Abstract

The invention relates to a wireless keyboard input method and device based on surface electromyography signal recognition, computer equipment and a storage medium. The method comprises the steps of distributing letter key values, selection keys and enter keys in a mobile phone Sudoku input method to different fingers in order; acquiring a surface electromyographic signal acquired through the double-arm ring; performing feature processing and nonlinear mapping on the 16-channel surface electromyogram signals extracted by the double-arm ring, and taking the 16-channel surface electromyogram signals as input of a BP neural network; performing iterative training on the BP neural network to obtain a BP neural network prior model; and according to the BP neural network prior model, identifying acurrently clicked finger, and according to a pre-allocated key position, generating a corresponding input instruction to realize human-computer interaction. According to the invention, a wireless keyboard input mode capable of supporting input of Chinese characters and English is realized, the accuracy of surface electromyogram signal identification is improved, and the accuracy of wireless keyboard input is improved.

Description

technical field [0001] The invention relates to the technical field of computer applications, in particular to a wireless keyboard input method, device, computer equipment and storage medium based on surface electromyography signal recognition. Background technique [0002] With the popularization of computer applications, computers are playing an increasingly important role in most industries. Judging from the current market, the vast majority of keyboards are still working hard in terms of appearance and usage. Not much has changed. Traditional keyboards use mechanical pressing methods to achieve input. There is a limit to the input speed of such keyboards, because traditional keyboards need to find the corresponding key for each character, and it will take a certain amount of time to move fingers to find the key. And the traditional keyboards are all planar, and the volume is relatively large. [0003] Clearly, traditional standard keyboards are susceptible to dust, gre...
