Embodiment Construction

[0069] The present invention will be described in further detail below in conjunction with the accompanying drawings and examples, but the embodiments of the present invention are not limited thereto.

[0070] Such as figure 1 As shown, the present invention proposes an e-mail communication system based on a motor imagery and visual attention hybrid brain-computer interface, which includes a visual stimulator, an EEG acquisition platform, a system control unit, a data processing module, a cursor control module, and Character input module. Wherein the system control unit, the data processing module, the cursor control module and the character input module are realized by programming in the computer.

[0071] Wherein, the visual stimulator includes a visual stimulator based on an LCD display and a visual stimulator based on an LED display. The LCD-based stimulator contains eight stimulus keys that generate SSVEP visual stimuli, distributed among the four borders of the screen....

Abstract

The invention discloses an email communication system and method based on a motor imagery and visual attention mixed brain-computer interface. The system comprises a visual stimulator, an electroencephalogram acquisition platform, a system control unit, a data processing module, a cursor control module and a character input module, wherein the visual stimulator comprises an LCD (Liquid Crystal Display)-based visual stimulator and an LED (Light-Emitting Diode)-based visual stimulator; the LCD-based visual stimulator is provided for a user in an interface display way, and the LED-based visual stimulator is implemented through a hardware circuit. According to the method, the motion control and target selection of a two-dimensional cursor are realized by simulating a computer mouse through the mixed brain-computer interface based on motor imagery and LCD visual attention, and input of email addresses and contents is realized by simulating a computer keyboard through the brain-computer interface based on LED visual attention; the working modes of the mouse and the keyboard are switched through a stimulation key in an LCD simulator. The system has the advantages of high cursor motion control accuracy, high robustness, high character input accuracy and the like.

Description

technical field [0001] The present invention relates to brain-computer interface technology and communication technology, more specifically, the present invention relates to an e-mail communication system and method based on motor imagery and visual attention hybrid brain-computer interface. Background technique [0002] The human brain communicates with the outside world or controls the external environment through neuromuscular channels, and many diseases can destroy these neuromuscular channels. For example, amyotrophic lateral sclerosis, brainstem stroke, spinal cord injury, cerebral palsy, Parkinson's, multiple sclerosis, and many others can damage the nerve pathways that control muscles or damage the muscles themselves. Those affected by these disorders may lose voluntary muscle control, resulting in motor dysfunction that prevents them from communicating with the outside world or controlling external devices. [0003] Brain-Computer Interface (BCI) monitors the user'...
