Abstract: A device to manage the projection of images onto a plurality of media, and to geometrically designate and model a plurality of selected areas on display surfaces. The display areas form a visual environment of a user. The designations and models result in an environmental geometric model. A controller interprets information provided by at least one spatial interaction device of the user in the environmental geometric model. The controller generates images to be projected onto the various display areas by at least one image projector in accordance with the actions of the user as detected by the spatial interaction devices.

Abstract: The present invention extends to methods, systems, and computer program products for processing multi-touch inputs. It provides a method for continuous recognition of multi-touch gestures performed by one or more users on at least one multi-touch input device. The invention in one aspect allows users to start interacting with one multi-gesture and subsequently perform any other multi-touch gestures, if they want it, without needing to lift all their fingers off the multi-touch input device between each multi-touch gesture.
