Eye tracking head mounted display
First Claim
1. A head mounted display device, the device comprising:
- a mount which secures the device near a user'"'"'s head;
a beam-splitter attached to said mount with movement devices, wherein said movement devices displace said beam-splitter about a center of rotation of an eye of the user, and wherein said beam-splitter;
reflects at least one output image toward the user'"'"'s eye, andtransmits light incident on said beam-splitter to the user'"'"'s eye;
an image projector, which projects said at least one output image onto said beam-splitter;
an eye-tracker which measures the viewing direction of an eye of the user and produces corresponding coordinate information; and
at least one processor, in communication with said eye-tracker and said movement devices, which commands said movement devices to reposition said beam-splitter based on said coordinate information,wherein the device further comprises a focusing lens to focus said at least one output image based on the current focal distance of the user'"'"'s eye.

Abstract
A head mounted display device has a mount which attaches the device to a user'"'"'s head, a beam-splitter attached to the mount with movement devices, an image projector which projects images onto the beam-splitter, an eye-tracker which tracks a user'"'"'s eye'"'"'s gaze, and one or more processors. The device uses the eye tracker and movement devices, along with an optional head-tracker, to move the beam-splitter about the center of the eye'"'"'s rotation, keeping the beam-splitter in the eye'"'"'s direct line-of-sight. The user simultaneously views the image and the environment behind the image. A second beam-splitter, eye-tracker, and projector can be used on the user'"'"'s other eye to create a stereoptic, virtual environment. The display can correspond to the resolving power of the human eye. The invention presets a high-resolution image wherever the user looks.
