Free-space gesture recognition for transaction security and command processing
View Patent ↗A sensor panel for detecting a free-space gesture signature conducted with a gesturing instrument by providing a panel mounted on a controlled system with multiple gesturing sensors in a two-dimensional arrangement to detect movement of a gesturing instrument, and an array of infrared (“IR”) type sensors adapted to detect movement of gesturing instruments which are distinguishable by heat; determining a sensor sequence from a series of sensor detection events responsive to movement of a gesturing instrument within the sensor proximity; correlating the sensor sequence to a predetermined seguence in order to authenticate a user of the gesturing instrument: and responsive to authentication of the user, authorizing a physical security action, wherein the a gesturing sensors comprise a combination of two or more sensors selected from Radio Frequency Identification type sensors acoustic sensors, acoustic type sensors adapted to detect movement of acoustic-reflective gesturing instruments, and infrared type sensors.
1. A method for detecting a free-space gesture signature conducted with a gesturing instrument, the method comprising:
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 the sensors comprise at least one type of sensor selected from a group consisting of an array of acoustic type sensors adapted to detect movement of acoustic-reflective gesturing instruments, and an array of infrared (“IR”) type sensors adapted to detect movement of gesturing instruments which are distinguishable by heat
determining a sensor sequence from a series of sensor detection events responsive to movement of a gesturing instrument within the proximity of the plurality of sensors;
correlating the sensor sequence to a predetermined sequence in order to authenticate a user of the gesturing instrument; and
responsive to authentication of the user, authorizing a physical security action,
wherein the providing a plurality of gesturing sensors comprises providing a combination of two or more types of sensors selected from a group consisting of Radio Frequency Identification (RFID) type sensors acoustic sensors, acoustic type sensors adapted to detect movement of acoustic-reflective gesturing instruments, and infrared (“IR”) type sensors.
