Abstract
A system and method that integrates an electronic pointer into digital image data, such as a video feed or software application, that is displayed on a screen. A receiver is provided that receives position data from a pointing device; a calibration unit then calculates the position of the pointing device relative to the screen based on the position data; and a processor then generates the electronic pointer based on the calculated position of the pointing device. Thereafter, the electronic pointer is integrated in the digital image data such that the video screen displays the electronic pointer at a location of the video screen that reflects the relative position of the pointing device to the video screen.
