Gesture based control using three-dimensional information extracted over an extended depth of field
First Claim
1. A system comprising:
- a plurality of optical detectors, wherein at least two optical detectors of the plurality of optical detectors comprise wavefront coded cameras, wherein the plurality of optical detectors image a body; and
a processor coupled to the plurality of optical detectors, the processor automatically detecting a gesture of a body, wherein the gesture comprises an instantaneous state of the body, wherein the detecting comprises aggregating only gesture data of the gesture and precluding use of background data in the detecting of the gesture, the gesture data comprising absolute three-space focus-resolved location data of an instantaneous state of the body at a point in time and space, the processor translating the gesture to a gesture signal and using the gesture signal to control a component coupled to the processor.

Abstract
Systems and methods are described for gesture-based control using three-dimensional information extracted over an extended depth of field. The system comprises a plurality of optical detectors coupled to at least one processor. The optical detectors image a body. At least two optical detectors of the plurality of optical detectors comprise wavefront coding cameras. The processor automatically detects a gesture of the body, wherein the gesture comprises an instantaneous state of the body. The detecting comprises aggregating gesture data of the gesture at an instant in time. The gesture data includes focus-resolved data of the body within a depth of field of the imaging system. The processor translates the gesture to a gesture signal, and uses the gesture signal to control a component coupled to the processor.
