Abstract
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 or a second state. 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 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.
