Abstract
A system (100) and method (160) for activating a touchless control is provided. The method can include detecting (162) a movement of a finger in a touchless sensing field, identifying (164) an activation cue in response to the finger movement, and activating (166) a touchless control of an object in response the activation cue. The method can include focusing the touchless sensing field (210) to produce a touchless projection space (220). An activation cue can be a positioning of a finger (302) within a bounded region (304) of the touchless projection space for a pre-determined amount of time. In one arrangement, cursor (124) navigation and control can be provided in accordance with touchless finger movements.
