Claim:
1. A mobile device comprising: a mobile base comprising a processor and a memory to produce an image; a projection device operatively coupled to the mobile base for displaying the image; and a transparent display surface comprising a holographic optical element and operatively coupled to the mobile base for directing the displayed image projected by the projection device, wherein the projection device is oriented to project the display image in a direction away from an operator of the mobile device, wherein the transparent display surface is oriented to reflect the display image toward the operator of the mobile device, wherein the holographic element refracts a first set of wavelengths of light from the projection device while allowing a second set of wavelengths of light from a background feature to pass through the holographic optical element and the transparent display surface towards the operator, and wherein the background feature is located behind the transparent display surface and the projection device is located in front of the transparent display surface.
