    摘要： Wireless sensing units, methods, systems, and processor-readable media for obtaining pressure data relating to one or more pressure locations of a surface area are described. A wireless sensing system includes a pressure monitoring device communicating with modular wireless smart floor tiles using RFID, either using an RFID reader or wireless network interface (e.g., 802.11). The tiles incorporate passive or active RFID tags. The tiles can be powered wirelessly, e.g. by a built-in piezoelectric power unit or by a wireless power source using magnetic resonance. A data capture circuit in each tile collects and saves the data for transmission to the floor pressure monitoring device. Various software applications can be enabled by the smart floor system, including fall detection and prediction, gesture input, intrusion detection, and user location tracking for smart home automation.

    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： 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.
