Head-mounted eye movement tracking device

Abstract

The invention discloses a head-mounted eye movement tracking device. The head-mounted eye movement tracking device is worn on the head of a user and comprises a head wearing piece, a micro infrared camera module arranged in the head wearing piece, an eye video image processing module, a wireless data transmission module and a power module. When the head-mounted eye movement tracking device is wornon the head, an infrared camera bracket on the head wearing piece is adjusted to be aligned with the eyes, thus presenting a clear eye image; eyeball movement tracks can be recorded, and reference isprovided for mental disease diagnosis; and human eye sight information can be tracked, and blinking actions can be detected and converted into mouse signals to control and use digital terminals suchas computers and mobile phones. According to the head-mounted eye movement tracking device, assistance can be provided for doctors to perform pathological examination and mental disease diagnosis on the eyes of patients, and the cursor can be controlled to roughly replace the mouse through the eye movement information, so that convenience is brought to people who are inconvenient to use the mouseby hands, and the equipment is low in cost and convenient to wear.

Description

technical field [0001] The present invention relates to the field of eye-tracking devices, in particular to a head-mounted eye-tracking device. Background technique [0002] The eye is an important organ for human beings to obtain information from the surrounding world. By accurately measuring a person's gaze point, it can provide an important basis for studying human psychological activities and extracting psychological awareness. The gaze point can be used instead of the mouse or touch operation to realize the use of gaze point Perform human-computer interaction; eye tracking devices, as a line-of-sight measurement device, have broad application prospects in all walks of life, including rehabilitation medicine, advertising design, game design and human-machine interface design and many other fields. Although eye-tracking devices have broad application prospects, most of the existing domestic eye-tracking devices are head-restricted. The subject needs to fix the head on a f...

AI Technical Summary

Problems solved by technology

Although eye-tracking devices have broad application prospects, most of the existing domestic eye-tracking devices are head-restricted. The subject needs to fix the head on a flat surface and the head cannot move during the measurement , very inflexible

Moreover, the distance between the camera and the human eye is relatively long, and the pixels of the human eye account for a relatively small proportion of each frame of image captured by the camera, which cannot avoid the interference caused by complex background images, resulting in high complexity and a large amount of calculation for tracking algorithms on non-wearable devices. , has high requirements for hardware computing speed, which occupies a lot of hardware resources of the controlled device, poor real-time performance, and poor user experience
