Abstract: Computing devices and methods are used to detect and compensate for the presence of a cover layer on a touch input device. A computing device includes a processing device, a touch input device in electronic communication with the processing device, and a memory device in electronic communication with the processing device and having electronic instructions encoded thereon. The electronic instructions, when executed by the processing device, cause the processor to receive a first signal obtained from the touch input device over a first duration of time, the first signal including a first signal pattern, receive a second signal obtained from the touch input device over a second duration of time separate from the first duration of time, the second signal including a second signal pattern, determine a difference between the first signal pattern and the second signal pattern, and adjust a touch input detection setting based on the difference.

Abstract: In one aspect, the present disclosure relates to a method and system for performing a noise correction technique including determining core electrodes and non-core electrodes, generating a noise estimate for each electrode based on electrodes that are at least an offset distance away from the electrode, correcting the signal at each electrode based on the noise estimate, and setting the corrected signal to zero if the corrected signal has a sign that is opposite the sign of the peak magnitude signal. By performing this method, noise induced on sense lines of a stylus by an LCD can be corrected for and accuracy of stylus positioning may be improved.

Abstract: Obstruction detecting logic may execute touch-sensing algorithms on the electronic device, which may detect when a user is gripping the electronic device from the side, when the fingers or hand of the user is on the edge of the electronic device, when the user is using one or more fingers to touch the electronic device, and may determine thumb and finger orientation. Using the touch-sensing methods, it may be determined which antennas are obstructed. To mitigate negative antenna performance due to the determined obstruction, one or more compensation actions may be taken. The touch-sensing algorithms may estimate user thumb/finger orientation and velocity, which may be used to predict future antenna occlusion (e.g., if the hand of the user is in motion).

Abstract: Grip detection can be beneficial for an electronic device to ignore unintended contacts on a touch sensitive surface. Examples of the disclosure provide various ways for identifying an input patch as a grip. In some examples, identifying an input patch as a grip comprises determining whether the input patch satisfies one or more grip identification criteria. In some examples, identified grips are saved in a grip database. In some examples, the identified grips are filtered out of touch images. In some examples, when baseline touch data for a touch-sensitive is updated, the touch processor can forgo updating the baseline for portions of the touch sensitive surface associated with the identified grips.

Abstract: 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.

Abstract: A touch screen or touch sensor panel can detect touches by conductive objects (e.g., fingers) and an active stylus and can mitigate noise in the sensed stylus signal from multiple noise sources. In some examples, the touch sensor panel includes a plurality of touch electrodes that can be used to sense touch data indicative of a proximate conductive object and to sense stylus data. The stylus data can include noise from one or more sources, for example. In some examples, the electronic device uses the touch data to determine a characteristic of one of the sources of noise and the stylus data to determine another characteristic of the source of noise and one or more characteristics of another source of noise. After modeling the noise, the electronic device can remove the noise from the stylus data to improve the accuracy of the stylus scan.
