Electrooculogram control system and method for controlling cursor by using eye electricity control system

Abstract

The invention discloses an electrooculogram control system for control on the basis of relative motion of an eyeball and a head, and a method for controlling a cursor by using the electrooculogram control system. The electrooculogram control system comprises a sensing device and a programmable logical control unit. The sensing device contacts the face of a human body and is used for detecting information on the relative motion of the eyeball and the head so as to respectively convert the information into respective electric-eye movement wave signal of the left eye and the right eye in the longitudinal and transverse directions. The programmable logical unit executes all operation controls and flows in a programming mode, judges and processes the operation controls and flows according to the electric-eye movement wave signal generated by the sensing device so as to control the movement of a mouse cursor and execute (rolling) functions of left, right, upper and lower keys. The method comprises the following steps of: A, setting a visual focus at a position which is different from that of the cursor; B, fixedly staring the position of a target point on a host computer by the visual focus; and C, moving the cursor to the position of the visual focus by using the relative motion of the eyeball and the head.

Description

technical field [0001] The present invention relates to a system and method for eye-controlled communication, in particular to an eye-electric control system that utilizes the relative movement of the eyeball and the head to control the displacement of the mouse cursor and to issue commands, and a method for controlling the cursor using the system. Background technique [0002] If you use your hands to control the mouse for a long time, your hands will have mouse syndrome. Therefore, there is an eye movement control device that uses the movement of the eyeballs to control the displacement of the mouse cursor, so as to overcome the problems of hand soreness and mouse syndrome caused by long-term operation. trouble, or for people with hand disabilities. [0003] The conventional eye-directed control device relies entirely on the movement of the eyeballs to control the displacement of the cursor. However, in the way of simply using the eyeball to control the cursor, the eyebal...

Problems solved by technology

[0006] The purpose of the present invention is to solve the technical problems that the traditional electrooculogram needs to use adhesive tape to paste the electrodes on the face, and the existing eye command control device needs a head fixing bracket, which is inconvenient to use.
