From Wikipedia, the free encyclopedia
(Redirected from EyeTap)
The EyeTap is a name for a device that is worn in front of the eye that
Acts as a camera to record the scene available to the eye, and
Acts as a display to superimpose a computer-generated imagery on the original scene available to the eye.
In order to capture what the eye is seeing as accurately as possible an EyeTap uses a beam splitter to send the same scene (with reduced intensity) to both the eye and a camera. The camera then digitizes the reflected image of the scene and sends it to a computer. The computer processes the image and then sends it to a projector. The projector sends the image to the other side of the beam splitter so that this computer-generated image is reflected into the eye to be superimposed on the original scene.
