Embodiment 1

[0090] see figure 1 , the present invention discloses a brain-controlled eye-moving assistant system for the disabled, including four parts: a vision-inducing interface, a signal acquisition device, a signal processing module, and a peripheral control device.

[0091] (1) Vision-evoked interface

[0092] The visual eliciting interface is the user interaction interface of the whole system, and the user uses this interface to control the whole process (such as figure 2 shown). The system has two control interfaces: the camera and smart car control interface, and the wheelchair control interface. Users can switch between the two control interfaces according to their needs.

[0093] layout. The user control interface consists of three parts: the video real-time feedback box, the control command display bar, and the face stimulus source. figure 2In the middle is the video real-time feedback box, which displays the video traffic information transmitted by the camera. The top ...

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...
