Abstract
A method may track a motion of a body part in a series of images captured by an imager that is associated with an electronic device, and detect in such motion a gesture of the body part that matches a pre-defined gesture. Upon such detection of the gesture, a function that is associated with the gesture is activated but only upon a contact or other input, such as a push of a button by a user. The combination of the ‘push to enable’ and the ‘gesture to activate the function’ may provide comfortable operation of the gesture activation of a function. A system and method of altering a zoom of an image displayed on an electronic device by detecting in a series of images a change in distance between the device and a viewer of the image, and zooming the image to correspond to such change in position. The captured images and detected change in distance may be interpreted by a processor as a zoom gesture that may trigger a zoom of the displayed image. A system and method of activating a scroll function for content that is displayed on an electronic screen, including capturing a series of images of a body part, such as a head, of a viewer of the content, and detecting a rotation, a change in orientation, or a change in a position of such head. A method may interpret the detected change as a gesture, and activate a scroll function to scroll the displayed content in a direction opposite the direction of the gesture or with other parameters defined by the detected gesture.
