Abstract
A video system such as a television signal receiver includes a touch screen that may be suitable for larger image screens. According to an exemplary embodiment, the video system includes a screen having first and second sides, wherein a depression of the screen on the first side produces an image detectable on the second side. At least one projector is disposed on the second side of the screen and projects a first video signal onto the screen. At least one camera is disposed on the second side of the screen and detects the image. A processor determines a location of the depression according to the detected image.
