Free-space gesture recognition for transaction security and command processing
First Claim
1. A method for detecting a free-space gesture signature conducted with a gesturing instrument, said method comprising the steps of:
- providing a panel mounted on a controlled system, the panel having a plurality of gesturing sensors in a two-dimensional arrangement, each sensor being adapted to detect a gesturing instrument within a proximity of a sensor, each sensor having an independent detection event signal, wherein said sensors comprise an array of Radio Frequency Identification (RFID) sensors adapted to detect movement of RFID devices;
determining a sensor sequence from a series of sensor detection events responsive to movement of a gesturing instrument within the proximity of said plurality of sensors;
correlating said sensor sequence to a predetermined sequence in order to authenticate a user of said gesturing instrument; and
responsive to authentication of said user, authorizing a physical security action.

Abstract
A sensor panel having a matrix of independently decoded sensors, arranged in a two-dimensional pattern allows a consumer identification unit (CIDU) to detect a user-specific gesture made with a gesturing instrument such as an RF ID device. The CIDU monitors on a timed basis which of the sensors in the panel are receiving a signal from an RF ID device which has entered the proximity of one or more of the sensors. The user moves the sensor in a two-dimensional pattern to perform a “gesture signature” in free space near the panel, and the CIDU records the sequence of receiving sensors. This sequence can then be quickly and efficiently handled as a number to be looked up to identify and authenticate the user. Preferably, the user is allowed to define multiple signature gestures, each having the possibility of being associated with a transaction or authorization level.
