Abstract
Disclosure herein concerns a method that includes illuminating a user's eye with an illumination source in a head-worn display, capturing an image of the user's eye with an eye camera in the head-worn display, wherein the image includes an eye glint produced by light from the illumination source that is reflected from a surface of the user's eye, determining a size of an eye glint in the captured image, and identifying a change in focus distance for the user's eye in correspondence with a change in the size of the eye glint.
Claims20
A wearable head device comprising:
- a see-through display configured to present content to an eye of a user of the wearable head device, such that presenting the content to the eye produces an eye glint;
- one or more sensors;
- and
- one or more processors configured to perform a method comprising:
- capturing, via the one or more sensors, an image of the eye glint;
- determining, based on the image of the eye glint, a level of sharpness associated with the content;
- in accordance with a determination that the level of sharpness is below a threshold, increasing the level of sharpness;
- and
- in accordance with a determination that the level of sharpness is not below the threshold, forgoing increasing the level of sharpness.
A method comprising:
- presenting, via a see-through display of a wearable head device, content to an eye of a user of the wearable head device, such that presenting the content to the eye produces an eye glint;
- capturing, via one or more sensors of the wearable head device, an image of the eye glint;
- determining, based on the image of the eye glint, a level of sharpness associated with the content;
- in accordance with a determination that the level of sharpness is below a threshold, increasing the level of sharpness;
- and
- in accordance with a determination that the level of sharpness is not below the threshold, forgoing increasing the level of sharpness.
A non-transitory computer-readable medium storing instructions which, when executed by one or more processors, cause the one or more processors to perform a method, comprising:
- presenting, via a see-through display of a wearable head device, content to an eye of a user of the wearable head device, such that presenting the content to the eye produces an eye glint;
- capturing, via one or more sensors of the wearable head device, an image of the eye glint;
- determining, based on the image of the eye glint, a level of sharpness associated with the content;
- in accordance with a determination that the level of sharpness is below a threshold, increasing the level of sharpness;
- and
- in accordance with a determination that the level of sharpness is not below the threshold, forgoing increasing the level of sharpness.
