Abstract
A method and a system for operating an electric apparatus are provided. In the present invention, first, an image capturing unit is enabled for capturing an image. Next, a palm component on the image is detected. Afterwards, a center of mass in the palm component is calculated according to a principal component analysis (PCA) algorithm, so as to use the center of mass to simulate a cursor. Then, a width of the palm of the palm component is calculated. Finally, the width of the palm is compared with a threshold so as to execute a click action if the width of the palm is greater than the threshold.
