摘要： Examples are disclosed relating to computing devices and methods for performing touch detection within a virtual trackpad area of a touch screen display. In one example, a non-trackpad touch input signal is received from outside the virtual trackpad area and processed with at least one touch detection algorithm applying a non-trackpad threshold value. A virtual trackpad touch input signal is determined to be received from within the virtual trackpad area. On condition of determining that the virtual trackpad touch input signal is received from within the virtual trackpad area, the virtual trackpad touch input signal is processed with the touch detection algorithm applying a virtual trackpad threshold value different from the non-trackpad threshold value.

摘要： The disclosure herein describes changing a mode of operation of a computing device using signals from a pen device. The pen device obtains gesture input data from at least one sensor of the pen device and the obtained gesture input data is compared to at least one gesture pattern. Based on the gesture input data matching the at least one gesture pattern, the pen device transitions to an active state. The pen device detects, via an electrostatic communication channel, an uplink signal from the computing device and sends a signal to change a mode of operation of the computing device by at least one of a network interface or a communication channel, other than the electrostatic communication channel. Changing modes of operation of a computing device provides a flexible, stream-lined way to enhance the user experience of using a computing device with a pen device (e.g., performing an initial pairing process).

摘要： Examples are disclosed relating to using a spatial noise model to compensate for noise in a frame of touch sensor data. One example provides, on a computing device, a method comprising receiving a noise level for each sensor antenna of a set of sensor antennas of a touch sensor; for each pair of sensor antennas, determining a noise compensation ratio comprising a noise level of a first antenna compared to a noise level of a second antenna; and storing the noise compensation ratio in a spatial noise model.

摘要： A computing device comprises a logic subsystem and a storage subsystem holding instructions executable by the logic subsystem to transmit a first identifier of the computing device to a separate electronic device, the first identifier being transmitted during one time frame of a plurality of sequential time frames. A second identifier of the computing device is transmitted to the electronic device, the second identifier including more data than the first identifier, the second identifier being transmitted over two or more time frames of the plurality of sequential time frames. An electronic pairing is established between the computing device and the electronic device based at least in part on one or both of the first and second identifiers, the electronic pairing enabling receiving of control inputs from the electronic device at the computing device.

摘要： A computing device is provided comprising a processor, a first display device having a first capacitive touch sensor, a second display device having a second capacitive touch sensor, and a hinge positioned between and coupled to each of the first display device and the second display device, the first display device and second display device being rotatable about the hinge and separated by a hinge angle. The processor is configured to detect the hinge angle at a first point in time, determine that the hinge angle at the first point in time is outside a first predetermined range, and upon at least determining that the hinge angle is outside the first predetermined range, perform run-time calibration of at least a plurality of rows of the capacitive touch sensor of the first display device and of the capacitive touch sensor of the second display device.

摘要： Examples are disclosed relating to computing devices and methods for performing touch detection within a virtual trackpad area of a touch screen display. In one example, a non-trackpad touch input signal is received from outside the virtual trackpad area and processed with at least a jitter restrictor algorithm that applies a non-trackpad distance between reported touch locations. A virtual trackpad touch input signal is received from within the virtual trackpad area. On condition of determining that the virtual trackpad touch input signal is received from within the virtual trackpad area, the virtual trackpad touch input signal is processed with the jitter restrictor algorithm that applies a virtual trackpad distance between reported touch locations that is smaller than the non-trackpad distance between reported touch locations.

摘要： A touch-sensitive display device includes one or more touch-sensitive displays each including a plurality of touch-sensitive electrodes. A free touch-sensitive electrode is identified on the one or more touch-sensitive displays that is (1) at least temporarily unaffected by proximity of one or more input objects to the one or more touch-sensitive displays, and (2) affected by an electrical noise caused by display of image content on the one or more touch-sensitive displays. The electrical noise affecting the free touch-sensitive electrode is measured. Based at least in part on the measured electrical noise affecting the free touch-sensitive electrode, and using a trained neural network, an amount of electrical noise caused by the display of image content that is affecting an occupied touch-sensitive electrode is estimated, the occupied touch-sensitive electrode being affected by proximity of the one or more input objects to the one or more touch-sensitive displays.

摘要： An active stylus includes a stylus tip and a pressure sensor disposed proximate to the stylus tip. A stylus controller is configured to receive, from the pressure sensor, a current pressure value quantifying a pressure measured at the stylus tip. The stylus controller receives, from a separate display device, a proximity indicator that indicates a current estimated proximity of the stylus tip to a surface of a touch-sensitive display of the display device. Based at least on both of (1) the proximity indicator received from the separate display device, and (2) a comparison between the current pressure value and a touch input pressure threshold, the stylus controller sends a touch status indicator to the separate display device.
