Examples are disclosed relating to noise compensation ratios in a spatial noise model to compensate for noise in a frame of touch sensor data. One example provides a computing device comprising a display, a touch sensor, a logic machine, and a storage machine comprising instructions. The instructions are executable by the logic machine to receive a noise level for each sensor antenna of a set of sensor antennas of the touch sensor. The instructions are further executable to, for each pair of sensor antennas of the set of sensor antennas, determine a noise compensation ratio comprising a noise level of a first antenna of the pair of sensor antennas compared to a noise level of a second antenna of the pair of sensor antennas, and store the noise compensation ratio in a spatial noise model.

Noise compensation using a spatial noise model

Devices are automatically paired (e.g., without user involvement) for wireless communication based on proximity. A first device may authorize (e.g., wired or wireless) bridge device(s) to participate in (e.g., initiate) pairing first and second devices. The first or bridge devices engage in wireless proximity communication with second device(s), indicating the second device(s) is(are) physically co-located with the first or bridge devices. Co-location is used to initiate automated pairing of the first and second devices. The second device provides a pairing address to the first device (e.g., through the bridge device). The first device provides a temporary security key for a secure channel between the first and second devices (e.g., through the bridge device). A non-temporary security key is provided by the first device to the second device (e.g., through the bridge device) over the secure channel. The first and second devices complete automated wireless pairing using the non-temporary security key.

Automated pairing of devices based on proximity detection

A method for electronic device identifier assignment at a host computing device includes receiving a current local identifier of a separate electronic device and a full unique identifier of the separate electronic device. A host-specific identifier is assigned to the separate electronic device by, based at least in part on determining that the current local identifier of the separate electronic device is included in a set of local identifier values available for assignment, assigning the host-specific identifier to the separate electronic device with a same local identifier value as the current local identifier. Based at least in part on determining that the current local identifier of the separate electronic device is already assigned by the host computing device to a different separate electronic device, the host-specific local identifier is selected from the set of local identifier values available for assignment and assigned to the separate electronic device.

Assigning device identifiers by host identifier availability

A method includes detecting presence of a handheld device in proximity of a touch enabled device and negotiating communication capabilities between the handheld device and a digitizer system of the touch enabled device. At least one of the handheld device and the digitizer system is configured to match a defined communication capability of the other of the at least one of the handheld device and digitizer system. Input from the handheld device is tracked via an electrostatic communication channel between the handheld device and the digitizer system based on the defined communication configuration.

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.

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.

A method is presented for providing haptic feedback through a touch-sensitive input device configured to provide input to a touch-sensitive computing device. The method comprises determining a haptic perception factor based on a set of computing device inputs received from sensors of the touch-sensitive computing device, the computing device inputs including at least a posture of the touch-sensitive computing device. A haptic response profile is determined based on the haptic perception factor. Haptic devices of the touch-sensitive input device are actuated based on the determined haptic response profile. Responsive to determining a change in the haptic perception factor based on a change in the posture of the touch-sensitive computing device the haptic response profile is then adjusted based on the changed haptic perception factor. The haptic devices of the touch-sensitive input device are then actuated based on the adjusted haptic response profile.

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.

Touch status indication for active stylus

A computing device including a wireless communication device, an electrostatic interface, and a processor. The processor may be configured to, via the electrostatic interface, detect a peripheral device proximate the surface. In response to detecting the peripheral device, the processor may be further configured to establish wireless pairing with the peripheral device at least in part by performing an identifier exchange via the electrostatic interface. Subsequently to performing the identifier exchange, establishing wireless pairing may further include generating a temporary key and transmitting the temporary key to the peripheral device via the electrostatic interface. Subsequently to transmitting the temporary key, establishing wireless pairing may further include receiving a first wireless pairing signal from the peripheral device via the wireless communication device. Subsequently to receiving the first wireless pairing signal, establishing wireless pairing may further include transmitting a second wireless pairing signal to the peripheral device via the wireless communication device.

A haptic response profile is determined based at least in part on the haptic perception factor. Haptic devices of the touch-sensitive input device are then actuated based at least in part on the determined haptic response profile.

Signals are transmitted from a plurality of regions of an electronic device. Location information is then received from an electronic pen in proximity to the electronic device. The location information is determined by the electronic pen and corresponds to a location of the electronic pen relative to the screen of the electronic device. The location information is determined using one or more of the transmitted signals received by the electronic pen. Aa display on the screen of the electronic device is controlled based at least in part on the received location information. A more efficient pen operating state is thereby provided that improves the user experience by more accurately and reliably determining the pen location in space.
