Abstract:
Acoustic touch and/or force sensing system architectures and methods for acoustic touch and/or force sensing can be used to detect a position of an object touching a surface and an amount of force applied to the surface by the object. The position and/or an applied force can be determined using time-of-flight (TOF) techniques, for example. Acoustic touch sensing can utilize transducers (e.g., piezoelectric) to simultaneously transmit ultrasonic waves along a surface and through a thickness of a deformable material. The location of the object and the applied force can be determined based on the amount of time elapsing between the transmission of the waves and receipt of the reflected waves. In some examples, an acoustic touch sensing system can be insensitive to water contact on the device surface, and thus acoustic touch sensing can be used for touch sensing in devices that may become wet or fully submerged in water.

Claim (Index 18):
A non-transitory computer readable storage medium storing instructions, which when executed by a device comprising a surface, a plurality of acoustic transducers coupled to edges of the surface, an acoustic touch and force sensing circuit, and one or more processors, cause the acoustic touch and force sensing circuit and the one or more processors to:\n for each of the plurality of acoustic transducers:\n simultaneously transmit an ultrasonic wave in the surface toward an opposite edge of the surface and transmit an ultrasonic wave through a deformable material; \n receive an ultrasonic reflection from the deformable material in response to the ultrasonic wave transmitted through the deformable material traversing the thickness of the deformable material; \n receive an ultrasonic reflection from the surface; \n determine a first time-of-flight between the ultrasonic wave transmitted through the deformable material and the ultrasonic reflection from the deformable material; and \n determine a second time-of-flight between the ultrasonic wave transmitted in the surface and the ultrasonic reflection from the surface; \n determine a position of an object on the surface based on respective second time-of-flight measurements corresponding to the plurality of transducers; and determine an amount of applied force by the object on the surface based on respective first time-of-flight measurements corresponding to the plurality of transducers.
