Methods, systems, and computer readable media for dynamic vision correction for in-focus viewing of real and virtual objects

A system for providing auto-focus augmented reality viewing of real and virtual objects, the system comprising:

• a frame for holding augmented reality viewing components on a user's head and optically in front of the user's eyes, the augmented reality viewing components including:
• an internal virtual objects display for displaying virtual objects;
• an internal focus correction module for adjusting a focal distance at which the virtual objects are displayed based on a vision type of a user and configurable to adjust the focal distance of the virtual objects differently for different user vision types;
• and
• an external focus correction module for adjusting focal distance of real objects based on the vision type of the user and configurable to adjust the focal distance of the real objects differently based on the different user vision types,
• wherein the internal and external focus correction modules operate to respectively adjust the focal distances of the virtual and real objects such that the virtual and real objects are simultaneously in focus based on the vision type of the user,
• wherein the external focus correction module includes a tunable lens through which the real and virtual objects are viewable and the internal focus correction module includes a deformable membrane mirror that reflects the virtual objects through the tunable lens and which is at least partially transparent to allow the user to view the real objects through the deformable membrane mirror,
• wherein, for a user having a hyperopic vision type, the external focus correction module operates in a static mode to apply a fixed positive dioptric lens power to statically shift the focal distances of the real objects and the internal focus correction module operates in a dynamic mode to change the focal distances of the virtual objects as the user accommodates to different real world distances as shifted by the external focus correction module, and
• wherein, for a user having a presbyopic vision type, the external focus correction module operates in a dynamic mode to change the focal distances of the real objects based on depths of the real objects and the internal focus correction module operates in a static mode to change the focal distances of the virtual objects to a focal distance at which the user is capable of accommodating.
