Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0024] The rotation of the neck is divided into five actions, turning left, turning right, looking up, looking down, and looking straight (the neck looks straight ahead), how to use signal processing methods to extract features of EMG signals, and use pattern recognition technology Realizing the correct classification of actions is the main problem to be solved by the present invention.

[0025] In the present invention, the accurate recognition of the five movemen...

Abstract

The invention discloses a method for identifying rotation of the neck. The method for identifying rotation of the neck includes the steps that a wireless electrode is used for collecting an epidermis electromyographic signal of the neck of the human body and transmitting the epidermis electromyographic signal to an electric signal receiving device; after the electromyographic signal is pretreated, an analog signal is converted into an electric signal through an analog-to-electric conversion device; the electric signal is transmitted into a chip to calculate the characteristics of electromyographic data, the linear discrimination analysis LAD method is used for processing the electromyographic data; an LDA classifier is trained, accurate classification of actions is achieved by the LDA classifier; channel change of a television is achieved, and operation of adjusting the volume is achieved. With the method for identifying rotation of the neck, interaction between the neck and the television is achieved through rotation of the neck.

Description

technical field [0001] The invention relates to the technical field of human-computer interaction, in particular to a method for identifying neck rotation. Background technique [0002] Brain-computer interface technology has been developing since the 1970s, and has made some remarkable progress so far, whether it is implanted cochlear products in the human body, or visual prostheses, or Duke University's research on langurs obtaining food, brain The development of the brain-computer interface has shown its charm, and now we are understanding the charm of the brain-computer interface from a new perspective. [0003] Pattern recognition refers to the process of processing and analyzing various forms of information representing things or phenomena to describe, identify, classify and explain things or phenomena. It is an important part of information science and artificial intelligence, and its main application fields are image analysis and processing, speech recognition, soun...
