摘要： A method for remotely controlling a computer (10) having an associated screen (16) for displaying output from the computer (10) and having an internal cursor (26) generated by the computer (10) includes at detecting least one property of an external cursor (22). In one embodiment, the invention includes a computer (10) connected to a projector (12), which projects an image of the computer (10) onto an external screen (16). A camera (14) is used to capture the image of the projected computer output. An optical pointer (24), such as a laser pointer, is used to generate and transmit an external cursor (22) having various properties, such as color, shape, or intensity. The image captured by the camera (14) is used to detect and process at least one property of the external cursor (22) to generate a corresponding command or commands to control the computer (10). Commands may be used to emulate control of the computer (10) typically provided by a pointing device such as a mouse or track ball.

摘要： A method for interfacing with a computer through a projected display of the computer using a laser pointer includes processing an image of the projected display captured by a camera, determining position of a laser pointer spot on the projected display, generating commands to position a computer mouse pointer at a screen position corresponding to the projected display, and generating a mouse click for the computer when a programmable laser pointer event occurs. Commands may be used to emulate control of the computer typically provided by a pointing device such as a mouse or track ball.
