VR Eye-Tracking Add-on for HTC VIVE Pro
Eye-tracking systems detect areas of interest to users at a given time by measuring eye position, eye movement and pupil size. There are many techniques for measuring and tracking eye movements. The most popular is the optical method, which reflects light (usually infrared) back from the eye and is then perceived by a camera or some other specially designed optical sensor. The data are then analyzed using algorithms to extract eye rotation from the changes in reflection. Optical methods are widely used in eye tracking as a non-invasive eye tracking method and are favored because they are non-invasive and inexpensive.
The Droolon F1 offers a plug-and-play eye-tracking accessory for VR headsets such as the HTC Vive Cosmos. The product line supports HTC's official eye-tracking SDK, SRanipal, which is more compatible with developer apps.

Application
As a new auxiliary interactive form, eye interaction helps users interact with elements in virtual reality scenes through eyes, realizing interactive content such as selection, aiming and attention feedback, and thus establishing multi-mode interactive system such as eye movement, handle, gesture and sound in virtual reality scenes.
Based on the physiological characteristics of human eyes, the user's fovea vision is presented as high definition, and the peripheral vision is presented as low resolution, which can improve the frame rate, reduce GPU pressure, reduce vertigo, and significantly improve the user's immersive control experience.
