1. A method of recognizing an aimed point or area in a viewing space of a display device, the method comprising:

  • obtaining, using an image sensor, at least one image of the viewing space;

    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;

    determining by the at least one processor, a location of the aimed point or area in the viewing space using a combination of;

    the data indicative of the location of the at least one pointing element,the data indicative of the location of the at least one predefined body part, andfeatures with respect to a motion path of the pointing element during a pointing gesture;

    determining the aimed point or area, while obtaining the data indicative of the location of at least one pointing element in the viewing space;

    detecting a change in an estimated time until the pointing element will reach a point in the viewing space where the pointing element is closest to the aimed point or area during the pointing gesture;

    determining a change in a motion vector of the pointing element during the pointing gesture, wherein the change in the motion vector relates to a change in a direction of the motion vector in a vertical axis; and

    executing a predefined command or message associated with at least the aimed point or area and the change in the motion vector.
