US Patent 12026344 Hover detection for touchscreens

Measured signal data, detected by a sensor array of a device, is used to create a generated representation from the measured signal data. The generated representation is compared with a measured representation of the measured signal data to create a correlation coefficient corresponding to a correlation between the generated representation and the measured representation of the measured signal data. A hover event is detected for the device if the correlation coefficient exceeds a first threshold. If the correlation coefficient does not exceed the first threshold, then the measured signal data is determined to not be indicative of a hover event.
