1. A method for operating an electronic apparatus, comprising:
- enabling an image capturing unit for capturing an image;
detecting a skin color sample of a face component in the image;
detecting a hand component in the image according to the skin color sample;
calculating a feature projection of the hand component according to a principal component analysis (PCA) algorithm, so as to obtain a palm component;
calculating a center of mass of the palm component according to the PCA algorithm, so as to use the center of mass to simulate a cursor;
calculating a palm width of the palm component according to the PCA algorithm; and
comparing the palm width with a threshold, so as to execute a click action if the palm width is greater than the threshold.

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.
