1. A method of operating a touchless user interface on an electronic device having a screen, the method comprising the electronic device:
- determining information regarding a movement of an input object in a touchless gesture input zone;
determining that said movement of the input object represents an engagement gesture which has been performed and that has crossed at least one boundary of the touchless gesture input zone at a point which is a predetermined lateral distance from an edge of said screen;
determining that a related input gesture has been performed; and
carrying out an operation on the device on the basis of the input gesture only if the engagement gesture has been recognised and if the input gesture is one of a subset of possible input gestures determined by the engagement gesture.

Abstract
A method of operating a touchless user interface on an electronic device is disclosed. The electronic device is configured to determine information regarding the position and/or movement of an input object. The method has the steps of: deciding that an engagement gesture has been performed; deciding that a related input gesture has been performed; and carrying out an operation on the device on the basis of the input gesture only if the engagement gesture has been recognized and if the input gesture is one of a subset of possible input gestures determined by the engagement gesture.
