Abstract
A method and apparatus of detecting an input gesture command are disclosed. According to one example method of operation, a digital image may be obtained from a digital camera of a pre-defined controlled movement area. The method may also include comparing the digital image to a pre-stored background image previously obtained from the digital camera of the same pre-defined controlled movement area. The method may also include identifying one or more pixel differences between the digital image and the pre-stored background image and designating the digital image as having a detected input gesture command.
