1. A projected display-interactive input mechanism comprising:
- a boundary definition mechanism capable of defining at least one input region over a first side of a display surface laterally coincident with a projected display projected onto the first side of the display surface;
a scanning mechanism capable of scanning an object within a three-dimensional space on the at least one input region within which one or more users may provide physical input to affect a state of the projected display;
an input identification mechanism capable of identifying an input represented by a scanned object in the three-dimensional space and of associating the input with at least one user corresponding to the at least one input region in which the scanned object was scanned; and
a communication mechanism capable of communicating information regarding scanned objects scanned by the scanning mechanism.

Abstract
An apparatus for detecting user interaction or another input with a projected display includes a boundary definition mechanism and a scanning mechanism. The boundary definition mechanism is capable of defining at least one input region. The scanning mechanism is capable of scanning the at least one input region for any objects therein. An input identification mechanism may identify the input identified by the object, movement of the object, or a change in the object'"'"'s position. That information may be used to alter the projected display.

15. A projected display-interactive input mechanism comprising:
-
a boundary definition mechanism capable of selectively defining one or more input regions, each of the one or more input regions being a region on and/or adjacent to an opaque display surface onto which a display is projected and which is capable of receiving user input on and/or adjacent to the opaque display surface to affect a state of the display; a scanning mechanism capable of selectively scanning the one or more input regions to detect objects placed within the one or more input regions; an input identification mechanism capable of identifying an input represented by a scanned object positioned on or adjacent to the one or more input regions and of associating the input with at least one user corresponding to the one or more input regions on and/or adjacent to which the scanned object was scanned; and a communication mechanism capable of communicating information regarding each scanned object. - View Dependent Claims (16, 17)

18. A projected display-interactive input mechanism comprising:
-
a boundary definition mechanism capable of defining at least one input region on a first side of a display surface; a scanning mechanism capable of selectively scanning at least some objects placed within a three-dimensional space over the at least one input region coincident with a display projected onto the first side of the display surface, in which one or more users may provide physical input to affect a display state; an input identification mechanism capable of identifying an input represented by a scanned object scanned by the scanning mechanism, and of associating the input with at least one user corresponding to the at least one input region in which the scanned object was scanned; and a communication mechanism capable of communicating information regarding each scanned object scanned by the scanning mechanism, and information regarding an input region the scanned object was scanned in. - View Dependent Claims (19, 20)
