A method, including receiving, by a computer executing a non-tactile three dimensional (3D) user interface, a first set of multiple 3D coordinates representing a gesture performed by a user positioned within a field of view of a sensing device coupled to the computer, the first set of 3D coordinates comprising multiple points in a fixed 3D coordinate system local to the sensing device. The first set of multiple 3D coordinates are transformed to a second set of corresponding multiple 3D coordinates in a subjective 3D coordinate system local to the user.
