Abstract: A computer-implemented method and system for controlling various electronic devices by recognition of gestures made by a user within a particular space defined in front of the user are provided. An example method may comprise generating a depth map of a physical scene, determining that a head of the user is directed towards a predetermined direction, establishing a virtual sensing zone defined between the user and a predetermined location, identifying a particular gesture made by the user within the virtual sensing zone, and selectively providing to the electronic device a control command associated with the particular gesture. The particular gesture may be performed by one or more characteristic forms provided by the user within the virtual sensing zone being in an active state. The characteristic forms are forms reliably distinguishable from casual forms by means of computer vision and having certain attributes, which can reliably reflect user intent.

Abstract: Provided are computer-implemented methods and systems for controlling devices using gestures and a 3D sensor that enables implementing the above. In one embodiment, the method proposed herein may be based on defining at least one sensor area within the space surrounding a user of a controlled device; associating this sensor area with at least one user gesture; associating the combination of the user gesture and sensor area with an actionable command; identifying the direction of the line of sight of the user and a focal point of the line of sight of the user; and, if the line of sight of the user is directed a sensor area, issuing an actionable command corresponding to the combination of the sensor area and the gesture that the user makes while looking at this sensor area.
