 While the API does not yet expose eye tracking capabilities a lot can be inferred about where the user is looking by tracking the orientation of their head. This is especially true of XR devices that have limited input capabilities, such as Google Cardboard, which frequently require users to control a "gaze cursor" with their head orientation. This means that it may be possible for a malicious page to infer what a user is typing on a virtual keyboard or how they are interacting with a virtual UI based solely on monitoring their head movements. For example: if not prevented from doing so a page could estimate what URL a user is entering into the user agent's URL bar.
