The disclosure relates to techniques for handling unintentional touch inputs on a touch-sensitive surface. Grip detection can be beneficial for an electronic device to ignore unintended contacts on atouch 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 whetherthe 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. 本公开涉及用于处理触敏表面上的无意触摸输入的技术。抓握检测对于电子设备忽略触敏表面上的非预期接触可能是有益的。本公开的示例提供了用于将输入贴片识别为抓握的各种方式。在一些示例中，将输入贴片识别为抓握包括确定该输入贴片是否满足一个或多个抓握识别标准。在一些示例中，所识别的抓握被保存在抓握数据库中。在一些示例中，从触摸图像中滤除该所识别的抓握。在一些示例中，当更新针对触敏的基线触摸数据时，该触摸处理器可放弃针对该触敏表
