Eye Gaze Detection to Determine Speed of Image Movement
First Claim
Patent Images
1. A head-mounted display (HMD), comprising:
- a head-mounted support;
an optical system attached to the head-mounted support, wherein the optical system comprises a display panel configured to generate a virtual image, wherein the virtual image is viewable from a viewing location;
an infrared light source configured to illuminate the viewing location with infrared light such that infrared light is reflected from the viewing location as reflected infrared light;
a camera configured to image the viewing location by collecting the reflected infrared light; and
a computer configured to determine a gaze axis based on one or more images of the viewing location obtained by the camera and control the display panel to move the virtual images within a field of view based on the gaze axis, a reference axis related to the HMD, and a tracking rate.

Abstract
A wearable computing device or a head-mounted display (HMD) may be configured to track the gaze axis of an eye of the wearer. In particular, the device may be configured to observe movement of a wearer'"'"'s pupil and, based on the movement, determine inputs to a user interface. For example, using eye gaze detection, the HMD may change a tracking rate of a displayed virtual image based on where the user is looking. Gazing at the center of the HMD field of view may, for instance, allow for fine movements of the virtual display. Gazing near an edge of the HMD field of view may provide coarser movements.

11. A method, comprising:
-
determining a gaze axis within a field of view of a head-mounted display (HMD), wherein the HMD is configured to display virtual images within the field of view; determining a reference axis related to the HMD; adjusting a tracking rate based on the gaze axis and the reference axis; and moving the virtual images within the field of view based on; the gaze axis; the reference axis; and the tracking rate. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A non-transitory computer readable medium having stored therein instructions executable by a computing device to cause the computing device to perform functions, comprising:
-
receiving eye-tracking images from a head-mounted display (HMD), wherein the HMD is configured to display virtual images within a field of view; determining a gaze axis from the eye-tracking images; determining a reference axis related to the HMD; calculating an angle difference between the gaze axis and the reference axis; adjusting a tracking rate based on the angle difference; and controlling the HMD to display the virtual images based upon the gaze axis, the reference axis and the tracking rate. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30)
