An interactive input system comprises an interactive surface; at least one proximity sensor in proximity with the interactive surface and generating output signifying user proximity to the interactive surface; and processing structure configured to process user input generated in response to user interaction with said interaction input system and output from the at least one proximity sensor, said processing structure controlling interactive input system operation based upon at least one of said user input and proximity sensor output.

Interactive input system and method

A multi-monitor computer system includes a plurality of display devices communicating with at least one computing device executing an application management procedure. The application management procedure enables an application window available on one display device to be moved entirely to another display device by selecting the other display device from a dialog box displayed in response to a pointer-dragging input gesture on the application window.

Method of displaying applications in a multi-monitor computer system and multi-monitor computer system employing the method

Calibration structure, method, and code for correcting non-orthogonal misalignment of a computer-generated image that is projected onto a large screen touch-detecting display, so that a computer-generated image appears substantially where the display is touched. Structure/method/code generates at least four calibration marks, respectively, substantially proximate four corners of a projected image to be displayed on the display. Structure/method/code, responsive to a touch on the large screen touch-detecting display where each of the four calibration marks is displayed, identifies horizontal and vertical coordinates of each touched location. Structure/method/code calibrates the projected image to the display after the four calibration marks have been touched. Structure/method/code, responsive to another touch on the display after calibration, displays a computer image substantially at the location of the another touch.

Projection display system with pressure sensing at a screen, a calibration system corrects for non-orthogonal projection errors

An interactive display system comprising a touch sensitive display surface for sensing pressure applied thereto and in response generating control signals indicating locations of the applied pressure, a personal computer for receiving the control signals and in response generating graphic images, and an LCD panel in combination with an overhead projector for receiving and projecting the graphic images onto the touch sensitive display surface at the indicated locations. The LCD panel and overhead projector may be provided an integral unit.

Projection display system with pressure sensing at screen, and computer assisted alignment implemented by applying pressure at displayed calibration marks

An interactive display system comprising a touch sensitive display surface for sensing pressure applied thereto and in response generating control signals indicating locations of the applied pressure, a personal computer for receiving the control signals and in response generating graph images, and an LCD panel in combination with an overhead projector for receiving and projecting the graphic images onto the touch sensitive display surface at the indicated locations. The LCD panel and overhead projector may be provided an an integral unit.
