A gesture lighting source output command method for commanding a lighting apparatus by a motion of a heat emitting object inside the three-dimensional space of a gesture decoding environment, wherein the improvement comprises the lighting apparatus including a lighting source and an asymmetrical gesture decoding device, the asymmetrical gesture decoding device comprising a casing with an embedded electronic controller and a set of two dual PIR sensors, geometrically arranged in a plane with an angle β with the vertical, dual PIR sensors that are rotated 2α degrees one relatively to the other, and fitted with specially designed ordinary Fresnel lenses, their beam axes forming an angle of 2γ degrees between each other, the above mentioned three angles (β, 2α, 2γ) establishing a main target area (MTA), a three-dimensional space of the gesture decoding environment being defined by a pyramid of base equal to the mentioned main target area (MTA) and vertex defined by the mentioned beam axes of the two mentioned dual PIR sensors, the motion of the heat emitting object being, although not restricted to, in geometrical planes parallel to the ground and inclined relatively to the asymmetrical gesture decoding device plane, and the such lighting source output command method including steps of:
- collecting the IR light emitted by a heat emitting object inside the three-dimensional gesture decoding environment, through the two dual PIR sensors set, through continuous scans as two-dimensional data sequence;
- evaluating if the heat emitting object gestures were performed inside the mentioned main target area (MTA) by processing the outputs of the two mentioned dual PIR sensors, in the embedded electronic controller;
- obtaining the two-dimensional data sequence for the heat emitting object motion, simultaneously, one data sequence from each dual PIR sensor;
- decoding the motion of the heat emitting object by computing the two-dimensional data sequence;
- determining whether the motion of the heat emitting object complies with a predetermined condition in the memory;
- issuing a command signal if the motion does comply with one predetermined condition in memory;
- outputting the command signal to the lighting source, and;
- commanding the lighting source by changing at least one parameter of the lighting source output if the motion of the heat emitting object complies with a predetermined condition.
