14. A display device, comprising:
-
a projector configured to project an image onto a display surface;
a control projector configured to project a pointer spot or a movable control spot on the display surface;
an activating mechanisms configured to differentiate between projection of the pointer spot or the control spot;
a sensor configured to detect a pattern traced by the movable spot on the display surface; and
a processor, coupled to the sensor, configured to correlate the traced pattern with a predefined command. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)
