Abstract
A sensor device (100) and method (300) for touchless finger signing and recognition is provided. The method can include detecting (304) a first pause of a finger in a touchless sensory space (101), tracking (306) a movement (140) of the finger, detecting (308) a second pause of the finger, creating (310) a trace (145) of the finger movement from the tracking, and recognizing (312) a pattern (146) from the trace. The pattern can be an alphanumeric character or a finger gesture. A user can accept or reject the recognized pattern via touchless finger control.
