Embodiment Construction
[0024] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.
[0025] Such as figure 1 As shown, it is the working interface diagram of the present invention. There are 8 P300 flashing keys around the interface, among which there are three "up" keys on the top, indicating upward movement, and three "down" keys below, indicating downward movement. There is a "stop" key, which indicates the selection target operation. After the system is started, a square target and a circular cursor appear randomly, and then the user is required to control the cursor to move to the target and realize the function key selection by watching the P300 flashing key and performing left and right hand motion imagination.
[0026] Such as figure 2 As shown, the present invention provides a function key selection method based on motor imagery and P300 EEG ...
