1. A method for controlling a device using gestures, the method comprising: capturing a three-dimensional (3D) image associated with a user of the device; identifying whether a line of site of the user is directed towards a predetermined area in a space surrounding the user, the predetermined area being a sensor area, the line of sight being an imaginary straight line between a position of eyes of the user and an object that the user views, wherein the line of sight is a beam crossing a point associated with a hand of the user; identifying a gesture made by the user substantially contemporaneously with the current line of sight; comparing the gesture to one or more predetermined gestures associated with the sensor area; and based on the comparison, selectively providing to the device a command corresponding to the combination of the sensor area and the gesture, wherein the sensor area is substantially flat and is disposed within a same plane as a display communicatively coupled to the device, wherein the sensor area includes a sensor area located outside the display and a sensor area adjacent with a boundary of the display.
