1. A system for intuitively pointing at a scene on a screen the system comprising:
- a 3-D imaging system capable of identifying at least a first and a second points on a pointing object in the field-of-imaging (FOI) of said imaging system; and
a computation system capable of calculating a pointing line extending from said first point through said second point towards said screen and to calculate an imaginary point on said screen at which said pointing line hits said screen.

Abstract
A system and method for identifying a pointing organ or a pointing device in a field of imaging of a 3-D imaging system and for calculating a line of pointing relative to this organ or device are disclosed. The method and system may be used to enable a user to communicate with computer programs, such as computer games, 3-D design programs and the like. The method and system may further employ a trigger-like mechanism to identify a movement of a user that may be interpreted as trigger activation.

8. A method for intuitively pointing at a screen and activating programs, comprising:
-
identifying a pointing object in a field of imaging of a 3-D imaging camera; identifying a first point and a second point on said pointing object, said first point is located substantially close to the rear end of said pointing object and said second point is located substantially close to the front end of said pointing object; calculating a pointing line, said line extends from said first point, through said second point towards said screen; identifying a hit point on said pointing line on said screen; and providing data of the location of said hit point on said screen. - View Dependent Claims (9, 10, 11, 12, 15)
