Abstract
This relates to system architectures, apparatus and methods for acoustic touch detection (touch sensing) and exemplary applications of the system architectures, apparatus and methods. In some examples, the acoustic touch sensing techniques described herein can be used on a glass surface of a display or touch screen. In some examples, an acoustic touch sensing system can be configured to be insensitive to contact on the device surface by water, and thus acoustic touch sensing can be used for touch sensing in devices that are likely to become wet or fully submerged in water.
