1. A system comprising: a first wavefront coded camera that comprises a first aspheric optical element and that is constructed to generate a first wavefront coded image of a scene that includes a body; and a second wavefront coded camera that comprises a second aspheric optical element and that is constructed to generate a second wavefront coded image of the scene; and a processor coupled to the first wavefront coded camera and the second wavefront coded camera, the processor being constructed to automatically detect a gesture of the body by using the first wavefront coded image and the second wavefront coded image, wherein the gesture comprises an instantaneous state of the body, wherein the detecting comprises aggregating gesture data of the gesture at an instant in time by detecting image data of at least one tag coupled to a part of the body from focus-resolved data generated from the first wavefront coded image and the second wavefront code image, the gesture data comprising focus-resolved data of the body within a depth of field of an imaging system that includes the first wavefront coded camera and the second wavefront coded camera, the processor constructed to translate the gesture to a gesture signal and use the gesture signal to control a component coupled to the processor.
