1. A method of operating a single device to generate prioritized control signals depending on user movement, user level, or both, the method comprising the step of:
a. emitting, by the single device, a first mechanical inaudible signal having a first predetermined frequency outside the human audible spectrum, the emitted first mechanical inaudible signal interacting with at least one user within an area of effect, wherein the interaction is at least one of reflection and refraction, and wherein the first predetermined frequency associated with a first user level;
b. detecting, by the single device, the interacted mechanical inaudible signal, the detected signal having a detected signal frequency;
c. processing, by the single device, the detected signal to determine movement of the one user by comparing the detected signal frequency to the first predetermined frequency;
d. controlling operations of the single device based on the detected user movement;
e. transmitting a signal based on the detected user movement for control of operations of a first external device;
f. detecting, by the single device, a second mechanical inaudible signal having at least a second predetermined frequency outside the human audible spectrum, the second mechanical inaudible signal from a handheld device, the second predetermined frequency different than the first predetermined frequency and wherein the second predetermined frequency associated with a second user level;
g. controlling, at the second user level, operations of the single device, the second user level higher than the first user level; and
h. transmitting a signal based on the second user level for control of operations of the first external device.
