1. A method for touchless gesture recognition comprising: detecting one or more gesture-related signals using an associated plurality of detection sensors; and evaluating the touchless gesture detected from the one or more gesture-related signals using an automatic recognition technique to determine if the touchless gesture corresponds to one of a predetermined set of gestures, wherein in determining a start of the gesture, a start is determined if the distance between the target object and at least one sensor decreases and the distance between the target object and at least another sensor increases, and a short term variance or an equivalent measure over a predetermined plurality of signal samples is less than a threshold.
