Abstract
A method of dynamically increasing an effective size of an eyebox of a head mounted display includes displaying a computer generated image (“CGI”) to an eye of a user wearing the head mounted display. The CGI is perceivable by the eye within an eyebox. An eye image of the eye is captured while the eye is viewing the CGI. A location of the eye is determined based upon the eye image. A lateral position of the eyebox is dynamically adjusted based upon the determined location of the eye thereby extending the effective size of the eyebox from which the eye can view the CGI.

A method of dynamically increasing an effective size of an eyebox of a head mounted display, the method comprising:
- displaying a computer-generated image (“CGI”) to an eye of a user wearing the head mounted display, the CGI perceivable by the eye within the eyebox;
- capturing an eye image of the eye while the eye is viewing the CGI;
- determining a location of the eye based upon the eye image;
- and
- dynamically adjusting a lateral position of the eyebox based upon the determined location of the eye thereby extending the effective size of the eyebox from which the eye can view the CGI,
- wherein displaying the CGI to the eye comprises:
- generating the CGI with a display source positioned lateral to the eye outside of a field of view of the eye;
- reflecting the CGI traveling along a forward propagation path within light bending optics to a reverse propagation path using an end reflector;
- and
- redirecting the CGI traveling along the reverse propagation path to be emitted from an emission surface positioned in front of the eye.
A method of dynamically increasing an effective size of an eyebox of a head mounted display, the method comprising:
- displaying a computer generated image (“CGI”) to an eye of a user wearing the head mounted display, the CGI perceivable by the eye within the eyebox;
- capturing an eye image of the eye while the eye is viewing the CGI;
- determining a location of the eye based upon the eye image;
- and
- dynamically adjusting a lateral position of the eyebox based upon the determined location of the eye thereby extending the effective size of the eyebox from which the eye can view the CGI, wherein dynamically adjusting the lateral position of the eyebox to extend the effective size of the eyebox includes adjusting the lateral position of the eyebox in real-time in response to the eye looking left or right,
- wherein displaying a CGI to an eye comprises:
- generating the CGI with a display source positioned lateral to the eye outside of a field of view of the eye;
- reflecting the CGI traveling along a forward propagation path within light bending optics to a reverse propagation path using an end reflector;
- and
- redirecting the CGI traveling along the reverse propagation path to be emitted from an emission surface positioned in front of the eye.
At least one non-transitory machine-readable storage medium that provides instructions that, when executed by a head wearable display, will cause the head wearable display to dynamically increase an effective size of an eyebox of the head wearable display by performing operations comprising:
- displaying a computer generated image (“CGI”) to an eye of a user wearing the head mounted display, the CGI perceivable by the eye within the eyebox;
- capturing an eye image of the eye while the eye is viewing the CGI;
- determining a location of the eye based upon the eye image;
- and
- dynamically adjusting a lateral position of the eyebox based upon the determined location of the eye thereby extending the effective size of the eyebox from which the eye can view the CGI, wherein dynamically adjusting the lateral position of the eyebox to extend the effective size of the eyebox includes adjusting the lateral position of the eyebox in real-time in response to the eye looking left or right,
- wherein displaying a CGI to an eye comprises:
- generating the CGI with a display source positioned lateral to the eye outside of a field of view of the eye;
- reflecting the CGI traveling along a forward propagation path within light bending optics to a reverse propagation path using an end reflector;
- and
- redirecting the CGI traveling along the reverse propagation path to be emitted from an emission surface positioned in front of the eye.
