摘要： 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.

摘要： User interface control based on elbow-anchored arm gestures is disclosed. In one aspect, there is provided a method of user interface control on a computing device based on elbow-anchored arm gestures. A visual user interface (VUI) screen is displayed on a display of a computing device. The VUI screen comprises a plurality of VUI elements arranged in a plurality of VUI element levels. Each VUI element level comprising one or more VUI elements. A spatial location of an elbow of an arm of a user and a spatial location of a wrist of the arm of the user are determined. A three-dimensional (3D) arm vector extending from the spatial location of the elbow to the spatial location of the wrist is then determined. A VUI element in the VUI screen corresponding to the 3D arm vector is then determined based on a predetermined 3D spatial mapping between 3D arm vectors and VUI elements for the VUI screen.

摘要： 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.
