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, 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.
