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.
