Claim:
A user interface apparatus comprising: a multi-touch display component comprising dimensions sufficient for at least a plurality of users for displaying at least one projected image and for receiving, from the plurality of users, a multi-touch input; a plurality of image projectors for projecting said projected image on said multi-touch display component; a plurality of cameras for sensing said multi-touch input; and a user interface software for interfacing a plurality of users, the user interface software is configured to: allocate a portion of the multi-touch display component as an attract zone comprising a plurality of visual objects; receive a first touch input on a first visual object of the attract zone from a first user and a second touch input on a second visual object of the attract zone from a second user; and dynamically allocate a portion of the multi-touch display component to the first user as a first zone comprising the first visual object in response to the first touch input and a portion of the multi-touch display component to the second user as a second zone comprising the second visual object in response to the second touch input, the first zone and second zone become independent from the attract zone and are independent from each other such that touch input from the first user is limited to the first zone and content is displayed in the first zone in response to the touch input from the first user and touch input from the second user is limited to the second zone and content is displayed in the second zone in response to the touch input from the second user, wherein the attract zone becomes available to receive a third touch input.
