Patent number: 11809637Abstract: 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 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.Type: GrantFiled: September 13, 2022Date of Patent: November 7, 2023Assignee: HUAWEI TECHNOLOGIES CO., LTD.Inventors: Wei Li, Wei Zhou, Sachi Mizobuchi, Ghazaleh Saniee-Monfared, Juwei Lu, Taslim Arefin Khan, Rafael Veras Guimaraes
