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.

Methods and systems for providing feedback for multi-precision mid-air gestures on a gesture-controlled device

Method and systems for controlling a display device, including detecting a mid-air gesture using a sensing device; mapping the detected mid-air gesture to locations of an interaction region, the interaction region including an on-screen region of the display device and an off-screen region that is located outside an edge of the on-screen region; and performing a display device control action upon detecting an edge interaction based on the mapping of the detected mid-air gesture to locations that interact with the edge of the on-screen region.

Methods and systems of display edge interactions in a gesture-controlled device

A gesture-controlled device and a method thereon are provided. The method includes capturing a plurality of video frames of a user's body and processing the plurality of video frames to allow detecting a portion of the user's body and to allow recognizing hand gestures. In response to detecting the portion of the user's body, the method includes generating at least one widget interaction region corresponding to the portion of the user's body. The method further includes recognizing, a mid-air hand gesture in the at least one widget interaction region, mapping the mid-air hand gesture to at least one virtual widget on the gesture-controlled device, and manipulating the at least one virtual widget based on the mid-air hand gesture. The method and device allow manipulation of virtual widgets using mid-air gestures on a gesture-controlled device.

Methods of detection of swipe gestures and filtering and locating desired information in a multi-attributed search space in response to detection of swipe gestures and devices for performing the same are provided. The method includes activating an attribute associated with at least one element of a list of elements having a visible list portion rendered on the viewing area, in response to receiving an activation input for the attribute and displaying a plurality of attribute field controls associated with the attribute, in response to its activation. The method further includes receiving a manipulation action of at least one attribute field control, updating an attribute value in response to the manipulation action, and updating the visible list portion based on the attribute value. The method may be used with touchscreen displays, and with virtual or augmented reality displays.

Devices and methods for fast navigation in a multi-attributed search space of electronic devices

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.

User interface control based on elbow-anchored arm gestures

Methods and apparatus for gesture-based control of a device in a multi-user environment are described. The methods prioritize users or gestures based on a predetermined priority ruleset. A first-user-in-time ruleset prioritizes gestures based on when in time they were begun by a user in the camera FOV. An action-hierarchy ruleset prioritizes gestures based on the actions they correspond to, and the relative positions of those actions within an action hierarchy. A designated-master-user ruleset prioritizes gestures performed by an explicitly designated master user. Methods for designating a new master user and for providing gesture-control-related user feedback in a multi-user environment are also described.

Methods and systems for controlling a device using hand gestures in multi-user environment

A touch input tool for interacting with a capacitive touchscreen display. The touch input tool includes a plurality of spaced apart conductive touchscreen touch elements arranged to simultaneously operatively engage a screen of the touchscreen display at a corresponding plurality of discrete respective touch locations.

Touch input tool and system

A method of managing user interface items in a visual user interface (VUI) is disclosed. In one aspect, the method comprises displaying a VUI screen on a display. The VUI screen comprises a scrollable area comprising a plurality of selectable items. The VUI screen provides a pin holder located at an edge of a display area of the display. The state of the pin holder and the second pin holder persists in response to changes in a visual state of the scrollable area. A selected item in the plurality of selectable items is pinned to the pin holder in response to detection of a pinning command. A visual state of the scrollable area is changed in response to detection of corresponding input. A pinned item corresponding to a selected pin from the pin holder is unpinned in response to detection of an unpinning command.

Managing user interface items in a visual user interface (VUI)

A method and system including sensing a touch event on a touchscreen display of an electronic device, and changing a display layout rendered on the touchscreen display in response to determining that the touch event matches a stylus shaft gesture that corresponds to interaction of the stylus shaft with the touchscreen display. The stylus shaft may be located between a first end and a second end of a stylus.
