METHOD AND SYSTEM FOR TOUCHLESS USER INTERFACE CONTROL
First Claim
1. A sign engine for controlling an object via touchless sensing comprising a sensing unit that detects at least one touchless finger sign;
- a pattern recognition engine operatively connected to the sensing unit that identifies at least one pattern in the touchless finger sign; and
a processor operatively coupled to the pattern recognition engine that performs an action on the object in accordance with the at least one pattern.

Abstract
A sensing unit (110) and method (200) for touchless interfacing using finger signing is provided. The sensing unit can include a sensor element (113) for tracking a touchless finger sign, a pattern recognition engine (114) for tracing a pattern in the touchless finger sign, and a processor (115) for performing an action on an object in accordance with the at least one pattern. The object may be a cursor, an object handled by the cursor, or an application object. A finger sign can be an touchless finger movement for controlling an object, or a touchless writing of an alpha-numeric character that is entered in an object. The processor can visually or audibly present the pattern in response to a recognition of the finger sign.
