摘要： There is provided a mechanism for controlling a transmission of data in a fragmentation transmission mode. When fragments are transmitted in a fragmentation transmission mode, it is determined whether the fragment frame is received successfully or whether an acknowledgment message for confirming a successful transmission of the fragment frame is received. In case the acknowledgment for the successful transmission of the one fragment frame is not received, or the fragment is frame is not successfully received, the fragmentation transmission mode is maintained and a retransmission of the fragment frame is initiated.

摘要： First and second frames are received by a wireless receiver. Modulation symbols in the first frame are determined and stored. If a cyclic redundancy check failure is determined for the first frame, the frame is not passed to medium access control. Modulation symbols in the second frame are determined and stored and a correlation factor is computed between the at least two modulation symbols from the first frame and the at least two modulation symbols from the second frame. If the receiver determines that the correlation factor exceeds a predefined threshold, it performs maximum ratio combining for modulation symbols from the first frame and modulation symbols from the second frame in order to obtain a combined frame. The combined frame is demodulated and cyclic redundancy check success is determined for the combined frame.
摘要翻译：第一帧和第二帧由无线接收器接收。确定并存储第一帧中的调制符号。如果为第一帧确定了循环冗余校验失败，则该帧不会传递给媒体访问控制。确定并存储第二帧中的调制符号，并且在来自第一帧的至少两个调制符号和来自第二帧的至少两个调制符号之间计算相关因子。如果接收机确定相关因子超过预定阈值，则它对来自第一帧的调制符号和来自第二帧的调制符号执行最大比率组合，以获得组合帧。组合帧被解调，并且为组合帧确定循环冗余校验成功。

摘要： Methods, devices, and processor-readable media for managing a virtual workspace shared by multiple devices are described. A unified GUI is presented to each device in which the other devices sharing the virtual workspace are represented by GUI elements, with the location of the other local devices present within the same local environment corresponding to a display location of the corresponding GUI element around the perimeter of the GUI screen. The locations of the other local devices are determined based on sensor data from the local devices, such as NFC radio data or other short-range sensor data, without the need for a dedicated, specially positioned camera or other sensor configured to track the devices within the local environment.

摘要： Methods and systems for selecting an object or location in an extended reality (XR) environment or physical environment are described. A first origin, including a first position and a first direction, and a second origin, including a second position and a second direction, are obtained by at least one sensor. An intersection of a first ray, casted from the first origin, and a second ray, casted from the second origin, is determined. A selected object or selected location is identified, based on the determined intersection. An identification of the selected object or the selected location is outputted.

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： 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.

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 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.
