Facebook working on mysterious ‘authentic’ robot eyeball that could track where humans are looking

Facebook has patented a new technology for an “authentic” robot eye.

The idea, granted in December, would let the social media company build a “high performing and realistic” eyeball that would be like an “animatronic device” to track humans’ eye movements.

Tracking eye movements is used in digital ads to detect what people look at, as well as by its parent company Meta’s virtual reality applications. This could make it easier to load virtual items in a VR environment – only generating items that the user is looking at.
