Abstract: A system includes a screen and a computer that detects an object near the screen and allows interaction between the object and the computer.

Abstract: A method of collaborating between a first computer associated with a first display at a first location and a second computer associated with a second display at a second location may include establishing a connection between the first and second computers, opening a virtual canvas on the first computer, the virtual canvas to be displayed on the first and second displays simultaneously, and sending an object between the first and second computers by sending data associated with the object on the virtual canvas stored on the first computer to the second computer to be stored locally, thereby creating a shared canvas on which objects are at a single location. Video conferencing may include sending a first live video stream from the first display to the second display to be viewed in a first video conference window separate from the virtual canvas on the second display and vice versa.

Abstract: A method of connecting a mobile device to a common display associated with a display computer controlling the common display, including, for each mobile device downloading a display application onto the mobile device, selecting the display computer for the common display in the display application, connecting the mobile device to the display computer, selecting, on the mobile device, what is to be displayed on the common display, and sending a data stream of the selection to the display computer to be displayed in a window on the common display corresponding to the mobile device.

Abstract: In a computing environment having a multiple input detection system including a detector that detects and transmits multiple simultaneous user inputs from different users at a same time, a method for processing inputs from different users across multiple application windows of one or more applications displayed on a single display of a user interface, resulting in a multi-user graphical user interface (GUI), the computing environment running an operating system (OS) designed to run with a single user GUI, the method including determining, in a primary application, separate from the OS, that a first user input corresponds to a first window and a second user input corresponds to a second window, the primary application sending the first and second user inputs to first and second secondary applications that run in parallel with the primary application, the first and second secondary applications being designed to run with the OS.
