Claim 15:
16. A gesture-controlled device comprising:
an image-capturing device;
a processor;
a memory coupled to the processor, the memory storing machine-executable instructions which, when executed by the processor, cause the gesture-controlled device to:
process a first plurality of video frames of a video captured by the image-capturing device to recognize hand gestures performed by a user of the gesture-controlled device;
activate a dragging mode for controlling a user interface control element in response to recognition of a dragging mode activation mid-air hand gesture in the first plurality of video frames;
process a second plurality of video frames of the video captured by the image-capturing device to recognize hand gestures performed by the user of the gesture-controlled device;
set a default dragging direction for a draggable graphical widget of the user interface control element in response to recognition of a direction setting mid-air hand gesture in the second plurality of video frames; and
move the draggable graphical widget of the user interface control element, by a predefined distance, in the default dragging direction in response to recognition of a dynamic discrete control mid-air hand gesture performed by the user in the second plurality of video frames.
