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.

Methods, devices, and processor-readable media for adjusting the control-display gain of a gesture-controlled device are described. Adjusting the control-display gain may facilitate user interaction with content or UI elements rendered on a display screen of the gesture-controlled device. The control-display gain may be adjusted based on a property of how a mid-air dragging gesture is being performed by a user's hand. The property may be the location of the gesture, the orientation of the hand performing the gesture, or the velocity of the gesture. A hand that becomes stationary for a threshold time period while performing the dragging gesture may adjust the control-display gain to a different level. Control-display gain may be set to a different value based on the current velocity of the hand performing the gesture. The control-display gain levels may be selected from a continuous range of values or a set of discrete values. Devices for performing the methods are described.

Methods, devices, and media are disclosed for mapping of input and output spaces in head-based human-computer interactions. In some embodiments, an end-to-end method is described for designing a head-based user interface, calibrating the interface to individual users, and interacting with a user in real time by mapping head-based user inputs to an output space in a way that optimizes the target selection efficiency of the interaction. Head orientation may be leveraged to define the mapping between the user input and the output space.

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.

System and method for managing a user interface for a foldable device are disclosed. The method includes: determining a folding state of the foldable device based on a folding angle of the foldable device; detecting an input gesture on one or more touch-sensitive display segments of a flexible display screen of a foldable device; determining a gesture type corresponding to the detected input gesture; determining whether the detected input gesture is a valid gesture or invalid gesture; and responsive to determining that the detected input gesture is a valid gesture, providing the gesture type corresponding to the detected gesture, the folding state of the foldable device, and display information to a software application or an operating system of the foldable device.
