A computer-implemented method, system, and program includes a behavior processing system for capturing a three-dimensional movement of a user within a particular environment, wherein the three-dimensional movement is determined by using at least one image capture device aimed at the user. The behavior processing system identifies a three-dimensional object properties stream using the captured movement. The behavior processing system identifies a particular defined behavior of the user representing a particular behavioral signal from the three-dimensional object properties stream by comparing the identified three-dimensional object properties stream with multiple behavior definitions each representing a separate behavioral signal for directing control of at least one machine. In response to identifying the particular defined behavior, a machine control system generates a control signal triggered by the particular behavioral signal for directing control of the at least one machine.
