Free-space gesture recognition for transaction security and command processing

A computer readable medium encoded with software for free space gesture signature conducted with a gesturing instrument, said software causing a processor to perform the steps of:

• receiving detection event signals from 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 output, the sensors being arranged on a panel mounted on a controlled system, 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.

A system for detecting a command or identifying value made by a user through a gesture signature conducted with a gesturing instrument, said system comprising:

• a panel mounted on a controlled system, the panel having a plurality of gesture sensors organized in a two-dimensional arrangement, each sensor having an independent detection event signal which is activated upon detection of a gesturing device within the proximity of a sensor, wherein said sensors comprise an array of Radio Frequency Identification (RFID) sensors adapted to detect movement of RFID devices;
• a gesture recognition processor having a plurality of inputs for said independent detection event signals, and for performing the steps of:
• 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;
• and
• responsive to said authentication of said user, controlling a physical security action.
