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.
