an eye detection system located within or about the external cabinet, the eye detection system configured to do the following;

locate an eye position of a person near the gaming machine;

generate corresponding image casting information that describes the eye position relative to a position of the gaming machine such that an image from the gaming machine may be projected to a retina of the person near the gaming machine;

track the eye position; and

generate updated image casting information according to a predetermined refresh rate; and

a retinal image system located within or about the external cabinet. The retinal image system configured to receive image casting information, including updated image casting information, from the eye detection system, the retinal image system including;

one or more light sources that generate light;

a light valve configured to produce an image by selectively transmitting light according to video information, and

a projection system configured to do the following;

receive the image from the light valve;

project the image onto the retina of the person using the image casting information, the projected image being confined to an area of the person'"'"'s eyes; and

change a direction of image projection according to the updated image casting information.

17. The gaming machine of claim 16 further comprising transmission optics configured to receive light from the one or more light sources and transmit the light to the light valve.

18. The gaming machine of claim 16 wherein the eye detection system includes a camera configured to capture an image that includes the eye of the person when the person is near the gaming machine.
