Assistance system for disabled people based on brain control mobile eye and control method for assistance system

Abstract

The invention discloses an assistance system for disabled people based on a brain control mobile eye and a control method for the assistance system. The system comprises vision inducing equipment, signal acquisition equipment, a signal processing module and peripheral control equipment, wherein the vision inducing equipment is used for providing a user interaction interface of the whole system, and a user carries out control by using the interface; the signal acquisition equipment is used for acquiring the brain electrical activity of the scalp, converting an acquired analog signal into a digital signal and transmitting the signal to the signal processing module; the signal processing module is used for analyzing acquired data in real time and controlling an experimental process; the peripheral control equipment comprises the mobile eye and a wheelchair; the mobile eye comprises an intelligent trolley and a camera holder arranged on the intelligent trolley; the peripheral control equipment can do corresponding motion according to a control instruction sent by the signal processing module. According to the assistance system for the disabled people based on the brain control mobile eye and the control method for the assistance system, the safety of wheelchair control can be improved.

Description

technical field [0001] The invention belongs to the technical field of intelligent control, and relates to an auxiliary system for disabled persons, in particular to an auxiliary system for disabled persons based on brain-controlled moving eyes; at the same time, the present invention also relates to a control method of the above-mentioned auxiliary system for disabled persons. Background technique [0002] Auxiliary equipment involves brain-computer interface Brain Computer Interface technology was kicked off by Jacques Vidal's research in the 1970s, and the following definition was made at the First International Conference on Brain-Computer Interface in 1999: "Brain-computer interface is A communication system independent of the normal output pathways consisting of peripheral nerves and muscles" (translation), in short, the use of thought to control peripheral devices. Today's brain-computer interface usually has the following components, optional visual eliciting equipme...

Problems solved by technology

This solution requires the use of an external camera and should only be used in familiar environments

In addition, the number of stacking times of P300 is fixed at 4 times, which is not conducive to the output efficiency of wheelchairs

[0008] In the above-mentioned wheelchair auxiliary system, the controlled object is only a wheelchair, and a person sitting in a wheelchair cannot observe the visual blind spots in an unfamiliar environment
