摘要： A gesture interactive operation method includes: receiving image information, about a hand part and provided by an image sensor, when the hand part is located within a sensing range of the image sensor; defining, through an image processor, a space relationship among sequentially-adjacent first, second and third fingers of the hand part in the image information; and analyzing the image information to generate first or second initiation signal and initiating to execute first or second operating mode on the display screen, respectively. The first initiation signal corresponds to the image information indicating that the second and third fingers are physically contacted with each other and the second finger is not physically contacted with the first finger. The second initiation signal corresponds to the image information indicating that the first and second fingers are physically contacted with each other and the second finger is not physically contacted with the third finger.
