Abstract
Methods and systems for discrete control of user interface elements such as graphical widgets are described. A first plurality of video frames are captured and processed to recognize hand gestures therein. A dragging mode is activated in response to a dragging mode activation hand gesture in the first plurality of frames. A second plurality of video frames are captured and processed to allow recognition of hand gestures therein. Dragging, an element of a user interface control, in response to recognition of a discrete control hand gesture in the second plurality of frames. The discrete control of a user interface control using mid-air hand gestures allows precise setting of system parameters associated with the user interface control.
