Abstract: Examples are disclosed relating to providing haptic feedback in a stylus while the stylus crosses a gap between two displays. In one example, a method comprises detecting one or more haptic triggering criteria, and at least on condition of detecting the one or more haptic triggering criteria, actuating the haptic feedback component to produce haptic output. Using a width of the gap between the displays, a stylus velocity, and a stylus direction, a crossing time for the stylus tip to cross the gap is calculated. At a first time after actuating the haptic feedback component, the method determines that the stylus tip crosses an inside edge of one of the displays. At least on condition of determining that the tip of the stylus crosses an inside edge of a display, the method continues to actuate the haptic feedback component for the crossing time.

Abstract: 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).

Abstract: The disclosed technology provides wireless uplink transmission from a computing device to a peripheral device by communicating over a wireless connection between a digitizer of the computing device and the peripheral device by a multiuse communication protocol in which the digitizer receives input from the peripheral input device to affect operation of the computing device, transitioning communication from the multiuse communication protocol to a dedicated uplink communication protocol in which communication between with the peripheral input device includes transmission of multiple consecutive uplink blocks before the digitizer accepts downlink communications from the peripheral input device, and transmitting, while using the dedicated uplink communication protocol, consecutive data uplink blocks representing an upload to the peripheral input device before the digitizer accepts downlink communications from the peripheral input device.

Abstract: Examples are disclosed relating to providing haptic output to a stylus. In one example, rotational position data indicating a rotational position of the stylus about a longitudinal axis of the body of the stylus is received. Travel direction data indicating a direction of travel of a tip of the stylus relative to a touch-sensitive screen of a computing device is also received. Using at least the rotational position data and the travel direction data, one or more characteristics of a drive signal are determined. The drive signal is then transmitted to a haptic feedback mechanism within the body of the stylus to generate haptic output at the body.

Abstract: 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.

Abstract: 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.

Abstract: A computing device has a digitizer control module configured to monitor signals received by receive electrodes and to detect in the monitored signals a signal from a second touch display of a second computing device in physical proximity to the computing device. The digitizer control module is configured to determine one or more locations on the first touch display at which the signals from the second touch display are received. A processor in the computing device is configured to compute a relative position of the second touch display with respect to the first touch display on the basis of the determined locations, and to use the computed relative position to treat the first touch display and the second touch display as a combined touch display.
