Methods and systems for providing feedback for multi-precision mid-air gestures on a gesture-controlled device

A gesture-controlled device comprising:

• an image-capturing device;
• a processor;
• and
• a memory coupled to the processor, the memory storing machine-executable instructions which, when executed by the processor, cause the gesture-controlled device to:
• detect, using the image-capturing device, a mid-air hand gesture conforming to a first dynamic dragging gesture over a respective first dragging distance;
• detect a speed of the first dynamic dragging gesture;
• compute a CD gain for a slider control based on the speed and a gain factor, the slider control configuring a system parameter and the CD gain determining a granularity of control for the slider control for configuring the system parameter;
• and
• generate an auditory feedback or a visual feedback indicative of the CD gain with the first dragging distance for either coarse or fine adjustment of the system parameter, the auditory feedback or the visual feedback including at least one of:
• adjusting a spacing of a plurality of scale ticks of the slider control based on the CD gain, a decreased spacing of a plurality of scale ticks of the slider control configured for fine adjustment of the slider control and an increased spacing of a plurality of scale ticks configured for coarse adjustment of the slider control;
• or
• adjusting a range of the slider control based on the CD gain, a shorter range configured for precise adjustment of the slider control and an increased range configured for coarse adjustment of the slider control.

A non-transitory computer-readable medium having machine-executable instructions stored thereon, the machine-executable instructions, when executed by a processor of a gesture-controlled device, cause the gesture- controlled device to:

• detect, using an image-capturing device, a mid-air hand gesture conforming to a first dynamic dragging gesture over a respective first draggina distance;
• detect a speed of the first dynamic dragging gesture;
• compute a CD gain for a slider control based on the speed and a gain factor, the slider control configuring a system parameter and the CD gain determining a granularity of control for the slider control for configuring the system parameter;
• and
• generate an auditory feedback or a visual feedback indicative of the CD gain with the first dragging distance for either coarse or fine adjustment of the system parameter, the auditory feedback or the visual feedback including at least one of:
• adjusting a spacing of a plurality of scale ticks of the slider control based on the CD gain, a decreased spacing of a plurality of scale ticks of the slider control configured for fine adjustment of the slider control and an increased spacing of a plurality of scale ticks configured for coarse adjustment of the slider control;
• or adjusting a range of the slider control based on the CD gain, a shorter range configured for precise adjustment of the slider control and an increased range configured for coarse adjustment of the slider control.
