Determining gaze direction to generate augmented reality content

This invention describes how augmented reality glasses can place virtual content in a user's view. It works by tracking where the user is looking and using that gaze to pinpoint a specific spot in their environment. The system then identifies the ground and calculates the distance from that ground to the pinpointed spot, using this measurement to generate and display AR content. Specifically, the invention uses a 'ray casting' method, projecting a virtual line from the user's eye to determine the exact point they are focused on.

Why it matters: Filed in 2023, the performance and integration of eye tracking into consumer eyewear devices have significantly advanced by 2026. This makes the precise ray casting from the pupil or iris, as claimed, more robust and accessible for generating AR content.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedEye tracking hardware, spatial mapping, AR rendering software
