Gesture recognition method and gesture recognition apparatus using the same
First Claim
1. A gesture recognition method, suitable for a gesture recognition apparatus having an image capturing unit, and comprising:
- transmitting an infrared signal, and detecting whether an object appears in a predetermined range based on a first infrared signal retrieved from the infrared signal being reflected;
when the object appears in the predetermined range, identifying a current position of the object according to a signal strength of the first infrared signal;
adjusting an image capturing range to face the object based on the current position to capture a plurality of images including the object and a plurality of second infrared signals retrieved from the infrared signal being reflected; and
recognizing the images to retrieve a horizontal movement direction of a gesture of the object within the predetermined range, and recognizing the second infrared signals to retrieve a depth movement direction of the gesture within the predetermined range.

Abstract
A gesture recognition method and an gesture recognition apparatus using the same method are proposed. The method includes the following steps: transmitting an infrared signal, and detecting whether an object appears in a predetermined range based on a first infrared signal retrieved from the infrared signal being reflected; when the object appears in the predetermined range, capturing a plurality of images including the object and a plurality of second infrared signals retrieved from the infrared signal being reflected; and recognizing the images to retrieve a horizontal movement direction of a gesture of the object within the predetermined range, and recognizing the second infrared signals to retrieve a depth movement direction of the gesture within the predetermined range.
