Novel human-machine interaction device based on eye-motion and head motion detection

Abstract

The invention discloses a computer system equipment real-time control system through detecting the eye and head movement signals; the control system amplifies an EOG signal; then through noise elimination treatment, the control system extracts and analyzes the related information of eye movement track in the EOG signal, and adds head movement compensation to achieve more accurate positioning so as to make real-time control on the computer system and equipment. The control system replaces the traditional human-computer interaction mode through button, switch, keyboard, mouse and other external devices, thereby having a strong sense of novelty and utility.

Description

Technical field [0001] The invention relates to biological science and computer science, and designs a novel human-computer interaction method that combines detection of eye movement and head movement to control equipment such as computer systems. technical background [0002] Computing and control systems often require human intervention and guidance to complete the tasks we need. Traditional human-computer interaction methods include using switches, buttons, mice, keyboards, and trackballs. But in some cases, these technologies will be incapable or not enough, such as human-computer interaction for the physically disabled and virtual reality human-computer interaction. [0003] The visual system is the most important part of the human sensory system. Studies have shown that more than 80% of information is obtained through the visual system in the process of human interaction with the external world. If the visual system is used to realize human-computer interaction, it w...

Problems solved by technology

[0005] The general EOG control device does not include a device to detect head movement, so the user must fix the head by some means to accurately locate the line of sight
