Abstract
A touchless sensing unit (110) and method (210) for calibrating a mobile device for touchless sensing is provided. The method can include evaluating (214) a finger movement within a touchless sensory space (101), estimating (216) a virtual coordinate system (320) from a range of finger movement, and mapping (218) the virtual coordinate system to a device coordinate system (330).
