摘要： Methods and apparatuses for controlling a selection focus of a user interface using gestures, in particular mid-air hand gestures, are described. A hand is detected within a defined activation region in a first frame of video data. The detected hand is tracked to determine a tracked location of the detected hand in at least a second frame of video data. A control signal is outputted to control the selection focus to focus on a target in the user interface, where movement of the selection focus is controlled based on a displacement between the tracked location and a reference location in the activation region.

摘要： 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.

摘要： 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.

摘要： Methods, devices, and processor-readable media for hand-on-wheel gesture controls are described. A steering wheel is virtually segmented into a plurality of radial segments. Each segment is assigned a semantic meaning. Control commands related to control functions are mapped to different virtual segments of the steering wheel. When a user performs a gesture on the steering wheel, the system recognizes the gesture and selects a control function based on the location of the hand relative to the steering wheel. In various embodiments, on-wheel hand gestures, on-wheel hand location, and voice commands may be used in various combinations to enable a user to perform a wide selection of functions using a small number of unique commands.

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： 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.

摘要： Devices and methods for controlling an electronic device are provided. The methods include recognizing a two finger input gesture on at least two touch sensitive surfaces of the electronic device and manipulating a slider control rendered on a display in response to recognizing the two finger input gesture. Recognizing the two finger input gesture includes detecting a first input gesture, including a swipe gesture on a first touch sensitive surface and detecting a second input gesture, including a static touch at a location on a second touch sensitive surface. The first input gesture and the second input gesture happen in a same time period. The static touch location may be a soft button of a plurality of buttons and the slider control may be rendered in response to the static touch on the soft button. The method may be used in an electronic device having multiple touchscreen displays.
