Wearable device having a display, lens, illuminator, and image sensor

Abstract

A wearable device is disclosed. The wearable device may include a display, a lens, an illuminator, an image sensor, and at least one processor. The display may be configured to present images. The lens may be configured to provide a view of the display to an eye of a user. The illuminator may be configured to illuminate the eye. The image sensor may be configured to detect illumination reflected by the eye. The at least one processor may be configured to cause the display to present an image, receive data from the image sensor, determine a gaze direction of the eye based at least in part on the data from the image sensor, and cause at least one of the display or the lens to be moved until the gaze direction is directed toward the image.

1 . A wearable device, wherein the wearable device comprises:
 a display configured to present images;   a lens configured to provide a view of the display to an eye of a user;   an illuminator configured to illuminate the eye;   an image sensor configured to detect illumination reflected by the eye; and   at least one processor configured to:
 cause the display to present an image; 
 receive data from the image sensor; 
 determine a gaze direction of the eye based at least in part on the data from the image sensor, the gaze direction indicative of the eye not focused on the image; and 
 cause at least one of the display or lens to be moved until the gaze direction indicated the eye is focused on the image.
