## Abstract

A gesture lighting source output command method for controlling a lighting apparatus, together with an asymmetrical, no facing, gesture decoding device for commanding a lighting source, by decoding gesture translational motions of a heat emitting object, e.g. a human hand, at distances up to 1.5 meters, in geometrical planes that may be not coplanar with the gesture decoding device plane, and comprising a casing with an embedded electronic controller and two dual PIR sensors, geometrically arranged in a special manner, rotated 2α degrees one relatively to the other, fitted with specially designed Fresnel lenses, their beam axis forming an angle of 2γ degrees between each other and an angle β with the vertical.

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.

### Claim 2 (depends on 1)

### Claim 3 (depends on 1)

The gesture lighting source output command method of claim 1, wherein the commanding motion of a heat emitting object in compliance with a predetermined condition, may represent an only motion, several repetitions of the same motion, or successive different motions of the heat emitting object inside the three-dimensional space of the gesture decoding environment.

### Claim 4 (depends on 1)

The gesture lighting source output command method of claim 1, wherein the lighting source output command method includes steps of:
collecting the IR light emitted by two heat emitting objects inside the three-dimensional gesture decoding environment, through the two dual PIR sensor sets, through continuous scans as two-dimensional data sequence;
obtaining the two-dimensional data sequence for both heat emitting objects motion, simultaneously, one data sequence from each dual PIR sensor;

determining whether the motion of both heat emitting objects complies with a predetermined condition in the memory;
issuing a command signal if the motion of both heat emitting objects does comply with a 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 objects complies with a predetermined condition.

### Claim 5 (depends on 1)

The gesture lighting source output command method of claim 1, wherein the asymmetrical gesture decoding device is located on an object different than the lighting source.

### Claim 6 (depends on 1)

The gesture lighting source output command method of claim 1, wherein one asymmetrical gesture decoding device commands more than one lighting source.
