PSVR 2 Eye Tracking lets you wink at people in VR

The PSVR 2's eye tracking can detect every eye blink, allowing you to wink in VR.

Details on eye tracking capabilities were revealed during Unity's GDC 2022 keynote at Playstation VR2.

In addition to tracking what you're looking at - your gaze - the report revealed that PSVR 2 can also track your pupil diameter and eye blinking status.

A person's pupil diameter expands in the dark and contracts in bright light, but it also changes depending on your emotional state. Theoretically, developers could use this to determine if you are experiencing a strong emotional reaction to what is happening at the moment. Applying pupil diameter to an avatar can change the nature of social virtual reality, and eye blink states can allow winking in social spaces. Also, horror game developers can choose the moment to induce panic in a much more targeted way.

However, the flagship eye-tracking capability is, of course, fovea rendering. This means that the system only renders what you are currently viewing at full resolution, thus freeing up performance as the rest of your view is at a lower resolution. This extra performance can be used to improve the graphical fidelity of the environment, or bring large-scale flat-screen games into virtual reality without the need to create lower quality assets.
