Description

Technical Field

[0001] The utility model relates to the technical field of eye tracking, in particular to an eye tracking device which is easy to assemble and disassemble. Background Art

[0002] Eye tracking is a scientific application technology that allows users to flip pages without touching the screen. In principle, eye tracking mainly studies the acquisition, modeling, and simulation of eye movement information. It has a wide range of uses. In addition to infrared devices, devices that acquire eye movement information can also be image acquisition devices, or even cameras on ordinary computers or mobile phones. With the support of software, these devices can also achieve eye tracking.

[0003] When a person's eyes look in different directions, there will be subtle changes in the eyes. These changes will produce extractable features. Eye tracking devices can extract these features through image capture or scanning, thereby tracking eye changes in real time and predicting the user's status and needs. Currently, most eye tracking devices are head-mounted. Head-mounted eye tracking devices are usually fixed with plastic buckles. Because the plastic buckles are too thin and have no elasticity, they are easily worn, which affects the disassembly and maintenance of the head-mounted eye tracking device. Therefore, it is very necessary to design an eye tracking device that is easy to disassemble and assemble. Utility Model Content
