[0125] figure 2 Shown is a system block diagram of a position / posture (or gesture / Gesture, hereinafter referred to as gesture) recognition system according to the first embodiment of the present invention. Please refer to figure 2 , the position / posture recognition system includes a first infrared LED 201 , a second infrared LED 202 , an infrared receiver 203 and a control circuit 204 . The control circuit 204 is used to control the infrared receiver 203 , the first infrared LED 201 and the second infrared LED 202 . Those of ordinary skill in the art can find that in the first embodiment, the position / posture recognition system of the present application does not have an image capture device (such as a digital camera) in the prior art at all. In this example, it is necessary to use pure infrared technology to determine the position of the external object, and further determine the moving track of the above-mentioned external object. What is more special is that the genera...

[0140] Figure 7 It is a system block diagram of the position / posture recognition system according to the second embodiment of the present invention. Please refer to Figure 7, the position / posture recognition system includes a first infrared LED 701 , a second infrared LED 702 , a third infrared LED 703 , an infrared receiver 704 and a control circuit 705 . The control circuit 705 is used to control the infrared receiver 704 , the first infrared LED 701 , the second infrared LED 702 and the third infrared LED 703 . Similarly, in the second embodiment, the position / posture recognition system of the present case does not need the image capture device (digital camera) of the prior art. In this example, a third infrared LED 703 is additionally added to the position / posture recognition system. In this way, in addition to identifying the left and right positions of the external objects, the up and down positions of the external objects can also be identified.

[0153] Figure 12 It is a system block diagram of the position / posture recognition system according to the third embodiment of the present invention. Please refer to Figure 12 , this position / posture recognition system includes a first infrared light emitting diode 1201, a second infrared light emitting diode 1202, a third infrared light emitting diode 1203, a fourth infrared light emitting diode 1204, an infrared receiver 1205 and a control circuit 1206 . The control circuit 1206 is used to control the infrared receiver 1205 , the first infrared LED 1201 , the second infrared LED 1202 , the third infrared LED 1203 and the fourth infrared LED 1204 . Similarly, in the third embodiment, the position / posture recognition system of the present case does not need the image capture device (digital camera) of the prior art. In this example, compared with the position / posture recognition system of the second embodiment, the position / posture recognition system adds a fourth infrared...
