MP4 (Mobile Pentium 4) player device based on motor imagery, and control method thereof

Abstract

The invention relates to an MP4 (Mobile Pentium 4) player device based on motor imagery, and a control method thereof, and belongs to the technical field of biomedicine and electrons. The device comprises a head-mounted wireless Bluetooth brain wave collection earphone and a playing equipment terminal, wherein a dry electrode sensor module is used for collecting a brain wave and inputting a signal into a preprocessing module; a preprocessing module amplifies and denoises the signal through an amplification circuit; a first signal conversion module converts a preprocessed analog signal into a digital signal; a first wireless Bluetooth module emits the digital signal through wireless Bluetooth and receives the audio signal of the MP4 player; and the playing equipment terminals receives the signal emitted from the first wireless Bluetooth module and converts the signal into a control command to control the operation of the MP4 player. The control method for the device adopts a control scheme that the motor imagery and SSVEP (Spinal Somatosensory Evoked Potential) are combined, and a user generates different electroencephalogram signals through corresponding motor imagery and SSVEP so as to realize the control command required by the user.

Description

technical field [0001] The invention relates to an MP4 player device based on motor imagery and a control method thereof, in particular to an MP4 player device and a control method based on combined control of motor imagery and SSVEP, and belongs to the fields of biomedicine and electronic technology. Background technique [0002] Recently, the emergence of brain-computer interface has provided people with a new way of entertainment. If the EEG signal can be combined with the player, it will have a revolutionary new way of realizing people's entertainment and leisure, making the brain The idea of ​​a signal directly controlling an external device becomes possible. In the medical field, the direct and urgent application of brain-computer interface technology is to provide a way for people with normal thinking but motor dysfunction to communicate and control the external environment, so as to at least improve their independence and confidence in life . At the same time, the ...

AI Technical Summary

Problems solved by technology

[0003] In the current field of leisure and entertainment, MP4 players are mainly operated by buttons or touch screens. The application of this type of player has certain limitations, and it needs to be operated manually by people, and it must be connected with the buttons or touch screen of the player. Screen contact, not suitable for people with motor impairment
