Multi-mode brain machine interface wheelchair control system

Abstract

The invention designs and realizes electrical wheelchair control based on a brain machine interface, so as to provide another will output way or an ability of interaction with the outside environment for the disabled of motor dysfunction or other person in related need and provide assists in the aspects of life and work. The actual system can enable the user to control steering, forward, backward, speed-up, speed-down, start, stop and the like of the wheelchair only through imagination and receiving stimulation of a vehicle-mounted computer.

Description

technical field [0001] The invention relates to a brain-computer interface wheelchair control system, which realizes a brain-computer interface system that directly controls the wheelchair through brain electricity. Background technique [0002] The concept of Brain-computer Interface (Brain-computer InterfaCe, BCI) began in 1973, which is a direct connection pathway established between the human or animal brain and external devices. Since the 1970s, with the development of neuroscience and computer technology, brain-computer interface has made great progress. At present, according to the different ways of obtaining brain signals, brain-computer interfaces can be divided into invasive and non-invasive. Implanting electrodes directly into the braincase is called invasive BCI; obtaining signals from the scalp is called non-invasive BcI. EEG (EleCtro-encephalograPhy, EEG) is a macroscopic phenomenon produced by the discharge of brain cell groups. When the brain is active, spec...

Problems solved by technology

This control method usually needs to calculate the output by averaging the signals that the user is subjected to repeated stimuli. The detection speed is slow, and the user looks at the stimulation signal for a long time, and because it is a synchronous working method, it is easy to get tired.
