[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.

Abstract

The invention provides a position identification system and a posture identification method using the same. A conventional mode that digital photography is needed to use is eliminated by the posture identification method, and a mode of infrared ray detection is adopted. In order to achieve track accuracy in identifying an external object, the scheme at least needs two infrared ray light-emitting diodes. When the first infrared ray light-emitting diode emits infrared rays, the other infrared ray light-emitting diode receives the infrared rays. Distance between the external object and the infrared ray light-emitting diodes used for detection is determined via emitting infrared light with different energy. Besides, time-sharing multiplexing is adopted so that distance of the external object to the aforementioned at least two infrared ray light-emitting diodes respectively can be mastered and thus the position of the external object can be mastered.

Description

technical field [0001] The present invention relates to a gesture recognition technology. More specifically, the present invention relates to a gesture recognition system and a gesture recognition method using simple infrared light as a detection basis instead of using photography. Background technique [0002] Gestures are a very primitive and natural way of signaling, so in daily life, gestures are one of the commonly used communication methods in human-to-human interaction. With the development of visual image detection, gesture interactive control, binocular depth recognition, augmented reality and other technologies; the topic of somatosensory interaction has spread all over the world, and has brought a large number of related product applications. [0003] Generally speaking, gesture recognition or gesture recognition, as far as existing technologies are concerned, uses image processing and recognition technology to allow computers or electronic products to recognize d...
