    摘要： Low-power touch detection can be beneficial for an electronic device to maintain touch detection and enable response to certain touch inputs in a low-power state (e.g., a sleep state), while consuming less power than touch detection during an awake state. For example, sensing touch during the sleep state can allow the electronic device to wake (e.g., transition from the sleep state to the awake state) in response to detecting a certain touch input (e.g., a tap or other touch input) on its touch screen while in the sleep state. Examples of the disclosure provide various ways for the electronic device to further reduce power consumption in the low-power state by simplifying the processing requirements for touch input to the touch-sensitive surface.

    摘要： In some embodiments, an electronic device in communication with a display and a touch-sensitive surface displays a user interface, and while displaying the user interface, the electronic device receives touch input comprising a contact detected on the touch-sensitive surface. In some embodiments, in response to receiving the touch input, and in accordance with a determination that the touch input satisfies first criteria, wherein the first criteria include a requirement that the contact continues to be detected in a predefined region of the touch-sensitive surface for longer than a time threshold, the electronic device displays a first indication that further input of a first type detected at the touch sensitive surface will cause the device to display a first system user interface. In some embodiments, in accordance with a determination that the touch input does not satisfy the first criteria, the electronic device forgoes displaying the first indication.

    摘要： The rejection of undesired touch events on a touch surface is disclosed. A weighted meta-centroid of all touch events can be computed. In some examples, touches can be weighted inversely to their size and distance to the nearest neighboring touch. In some examples, touches can be weighted based on the size of their minor radii. A meta-ellipse can be fit to the weighted touch events. In some examples, the major axis of the meta-ellipse can be used to determine the orientation of a user's hand to reject undesired touches. In other examples, touches within the meta-ellipse can be rejected.

    摘要： A touch sensitive device that detects the occurrence of an electrostatic discharge event on the device by analyzing an acquired touch image for characteristics associated with the occurrence of an ESD event is provided. An acquired touch image is analyzed for characteristics that differentiate it from a touch image generated by a user input and are correlated with an expected touch image generated by an ESD event.

    摘要： A touch sensitivity of a touch-sensitive surface can be adjusted based on a state of a device including the touch-sensitive surface. The state of the device can be a first state (e.g., a grounding condition unknown or inferred to be poorly-grounded) or a second state (e.g., grounding condition inferred to be well-grounded). In the first state, for example, the touch sensing system of the device can be programmed to recognize and process a wide range of touch signals including relatively weak touch signals, which may correspond to water, liquid or other unintentional touches. In the second state, for example, the touch detection threshold can be adjusted to better reject water or unintended touches in the second state. In some examples, a ratio of measurements captured using the different types of scans of a selected touch node can be used to determine the state of the device.

    摘要： Touch input processing for touch-sensitive devices can be improved by filtering unintended contact detected on a touch-sensitive surface. In wet environments in particular, water on the touch-sensitive surface can be erroneously detected as touch input and degrade touch performance. In some examples, input patches can be classified as touch patches or non-touch patches prior to computationally-intensive touch processing. Filtering out unintended touches classified as non-touch patches can reduce processing requirements and save power. Additionally, classifying input patches can improve touch performance in wet environments. In some examples, input patches can be classified as touch patches or non-touch patches based on characteristics of edge touch nodes. In some examples, input patches can be classified as touch patches or non-touch patches based on a state-based signal threshold.

    摘要： The dynamic adjusting of the conditions for identifying inputs as touching a touch-sensitive device is discloses. In some examples, in addition to using a signal density make threshold to identify an input patch as touching the surface, a signal density stability threshold can be used to identify the input patch as touching the surface. In some examples, a weighted average of peak signal density contributions from recent identified touches can be computed to dynamically adjust the make threshold for new input patches. In other examples, a new input patch identified as associated with the same path as an earlier touch can have its “make” threshold dynamically adjusted based on the earlier touch without computing a weighted average.
