摘要 |
A display system with a pointer that is not restricted by wires or sensors. The display uses a spatial light modulator (14) for projecting an image on the screen (20). During a time period when all of the cells of the modulator (14) are in the same state, a cursor projected onto the screen by the pointer is reimaged from the screen to a detector (26), which translates the cursor image into signals for a central processing unit (38). The central processing unit (38) then directs the system as to what tasks are being dictated by the cursor. <IMAGE> |
