The BCI electric wheelchair collects multimodal signals such as brainwave, eye wave, and head movement from the user through the headband, thereby achieving virtual cursor movement control and click control. Combined with the wheelchair control interface, it realizes functions such as starting, stopping, advancing, retreating, accelerating/decelerating, left/right turning, etc. of the wheelchair. This product can help patients with physical disabilities, especially those with complete paralysis, to engage in physical activities, greatly expanding their range of activities, improving their quality of life, and reducing the nursing burden on their families and society.
