INTERACTIVE DISPLAY APPARATUS AND OPERATING METHOD THEREOF
First Claim
1. An interactive display apparatus comprising:
- a capturing unit operable to capture an image including a projected image which is displayed on a projection screen and a light of a pointing device irradiated onto the projection screen;
a memory which stores the captured image;
a detection unit which determines coordinate information for the light of the pointing device irradiated onto the projection screen based on the captured image; and
a controller which determines whether the light of the pointing device is moved outside of the projected image based on the coordinate information, and controls the apparatus to perform a predetermined operation from among a plurality of predetermined operations if the light of the pointing device is moved outside of the projected image.
