摘要： Detecting touch input includes, over a series of touch-sensing time frames, interpreting electrical conditions of display electrodes of a touch-sensitive display device to estimate frame-by-frame positions of two or more stylus electrodes of an active stylus. Based on the estimated frame-by-frame positions, future positions of each of the two or more stylus electrodes during a future touch-sensing time frame are predicted. Regions of interest on the touch-sensitive display device are identified, each region of interest including a plurality of display electrodes surrounding the predicted future position of a stylus electrode of the two or more stylus electrodes. During the future touch-sensing time frame, display electrodes in the regions of interest are selectively scanned.

摘要： The disclosure herein describes causing a computing device to transition from a low power state using 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 generates a wakeup event message. The pen device transmits the wakeup event message to the computing device using a communication protocol that the computing device is configured to receive in the low power state. The described power state transition method provides a flexible, customizable way for users to wake up computing devices using the pen device.

摘要： Examples are disclosed herein that relate to various operational modes of a capacitive touch sensor. One example provides a touch-sensitive input device comprising receive circuitry, a capacitive touch sensor having a plurality of portions, and a controller. The controller is configured to, responsive to not detecting a finger or a pen, operate the touch sensor in a locating mode by successively driving each portion with a fixed DC voltage and multiplexing the portion to the receive circuitry in a predefined sequence, and responsive to detecting the pen, operate the touch sensor in a tracking mode by driving a selected portion with the fixed DC voltage and multiplexing the selected portion to the receive circuitry to track the pen, the selected portion selected based on a detected location of the pen relative to the touch sensor and being varied as the detected location changes.
