Abstract:

Methods, systems, and computer readable media for minimal-latency tracking and display for matching real and virtual worlds in head-worn displays are disclosed. According to one aspect, a method for minimal-latency tracking and display for matching real and virtual worlds in head-worn displays includes calculating a desired image, calculating an error image as the difference between the desired image and an image currently being perceived by a user, identifying as an error portion a portion of the error image having the largest error, updating a portion of a projected image that corresponds to the error portion, and recalculating the image currently being perceived by a user based on the updated projected image.
