Abstract

A touch sensitive holographic display system includes a transparent screen having a rear side and a front side. A projector is configured for creating a holographic image at the front of the screen by projecting an image towards the rear side of the screen. The projector is located at the rear side of the screen. A touch sensor is configured for sensing a touching of the holographic image at the front side of the screen. An electronic controller is connected to the projector for controlling the projector and is connected to the touch sensor for receiving an indication that the holographic image has been touched. By touching the image, which can be an icon, a user can control or access a function of an automobile.

Claims

1. A touch sensitive holographic display system, comprising:

a transparent screen having a rear side and a front side;
