摘要：
A display screen interface implementation in a computer controlled user interactive display system, for enabling an interactive user to select specific items on a large presentation display screen, comprising laser apparatus for projecting a laser beam pointer image onto the display screen, apparatus for interactively moving the projected laser pointer orthogonally with respect to the display screen, apparatus for tracking the orthogonal movement and position of the projected laser bean pointer and apparatus enabling the user to make interactive selections on the display screen based upon the orthogonal position of the projected laser bean pointer. For best results in preferred embodiments, the laser beam pointer is handheld.
