Claim:
1. A method of recognizing an aimed point or area on a display, the method comprising: obtaining at least one image of a viewing space of an image sensor; processing the at least one image by at least one processor operatively connected to the image sensor and obtaining data indicative of a location of at least one pointing element in the viewing space; obtaining data indicative of a location of at least one predefined body part of a user in the viewing space; and determining features with respect to a motion path of the pointing element during a pointing gesture as the pointing element approaches the aimed point or area, the features including a plurality of position data components of the at least one pointing element during the pointing gesture which comply with a predefined criterion; determining, for each given position data component, a respective viewing ray, the respective viewing ray extending from the location of the at least one predefined body part, through the location of the at least one pointing element, and intersecting the display, thus yielding a respective candidate plane, wherein the location of the at least one pointing element corresponds to the given position data component; determining an overlapping area between the respective candidate planes; determining, by the at least one processor, the aimed point or area using data indicative of the overlapping area; and executing a predefined command and/or message associated with the determined aimed point or area.
