TRACKING OF WEARER'S EYES RELATIVE TO WEARABLE DEVICE

摘要

Techniques and architectures may involve operating a wearable device, such as a head-mounted device, which may be used for virtual reality applications. A processor of the wearable device may operate by dynamically tracking the precise geometric relationship between the wearable device and a user's eyes. Dynamic tracking of eye gaze may be performed by calculating corneal and eye centers based, at least in part, on relative positions of points of light reflecting from the cornea of the eyes.

主权项

1. A system comprising:
a light emitter to emit light toward an eye of a subject; a camera to capture an image of a cornea of the eye having one or more glints generated by reflection of the light from a surface of the eye; and a processor to:
calculate a center of the cornea based, at least in part, on relative positions of the glints in the image.
