A conferencing system comprises a plurality of computing devices communicating over at least one network during a conference session, at least one of the computing devices being configured to share content displayed thereby with other computing devices, the other computing devices displaying the shared content, at least one of the computing devices also being configured to accept input annotations made on the displayed shared content and to share input annotations with other computing devices over a channel independent of the shared content.

Annotation method and system for conferencing

A method comprises receiving an input event generated when at least one contact is made on an interactive surface at a location corresponding to a graphical object; determining the number of contacts associated with the input event; tracking movement of the at least one contact on the interactive surface; identifying a graphical object manipulation based on the number of contacts, the movement of the at least one contact, and the graphical object type; and performing the graphical object manipulation.

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.

A projection unit comprises a first light source outputting light that is used to project an image during normal projection unit use, and a second light source outputting light of a different intensity that is used to project an image outside of normal projection unit use.

A touch system comprises overlapping coordinate input sub-regions defining a generally contiguous input surface. Each coordinate input sub-region generates pointer coordinate data in response to pointer contacts thereon. When a pointer contact is made on a region of a coordinate input sub-region that overlaps with an adjacent coordinate input sub-region, each overlapping coordinate input sub-region processes acquired images to derive pointer data and triangulates the position of the pointer using the derived pointer data. Thereafter, the triangulated positions generated by the overlapping coordinate input sub-regions are processed in accordance with defined logic thereby to determine the position of the pointer contact relative to the touch surface.

A touch system comprises a large scale touch surface on which an image is presented and at least two imaging devices looking across the touch surface and having overlapping fields of view. Processing structure communicates with the imaging devices and processes image data acquired by the imaging devices to determine pointer contacts on the touch surface using triangulation. The processing structure further executes at least one application to facilitate user interaction with the touch surface. Methods of interacting with the touch surface are also disclosed.

A gesture recognition method includes detecting multiple pointers in close proximity to a touch surface to determine if the multiple pointers are being used to perform a known gesture. When the multiple pointers are being used to perform a known gesture, executing a command associated with the gesture. A touch system incorporating the gesture recognition method is also provided.

A tiled touch system comprises a display on which a computer-generated image is presented. The image is formed of an array of image segments. A digitizer is mapped to the display and senses pointer contacts made thereon.
