摘要： Devices and methods for providing feedback for a control display (CD) gain of a slider control on a gesture-controlled device are described. The method includes detecting a speed of a dynamic dragging gesture, determining the CD gain for the slider control based on the speed, and generating an auditory feedback or a visual feedback for the CD gain. A gesture-controlled device, which carries out the method, may have an image-capturing device, a processor, and a memory coupled to the processor, the memory storing machine-executable instructions for carrying out the method. Advantageously, providing feedback for CD gain of a slider control facilitates accurate adjustment of a system parameter associated with the slider control. The devices and methods may be used in industrial applications, vehicle control among other applications.

摘要： Methods and apparatuses for controlling a selection focus of a user interface using gestures, in particular mid-air hand gestures, are described. A hand is detected within a defined activation region in a first frame of video data. The detected hand is tracked to determine a tracked location of the detected hand in at least a second frame of video data. A control signal is outputted to control the selection focus to focus on a target in the user interface, where movement of the selection focus is controlled based on a displacement between the tracked location and a reference location in the activation region.
