Abstract
A method and system (500) for generating an approximately planar sensory field (199) and confirming a presence of an object (310) in the field is provided. The system can include at least one paired receiver (121/122) and at least one transmitter (130) in a front and back orientation of a touchless sensing unit (110). The method can include detecting a movement of the object within a sensory space (176/177), estimating a phase angle of the movement; and evaluating whether the phase angle is within a predetermined range (197), and if so, confirming a presence of the object within the approximately planar sensory field.
