Methods and devices for determining user input location based on device support configuration
First Claim
1. A method for determining a location of an input on a surface of a device, the location determined using a plurality of acoustic sensing elements, the method comprising:
- determining a current support configuration of the device from a plurality of possible support configurations for the device, each possible support configuration having a respective device acoustic signature used to resolve the location of the input on the surface of the device;
selecting a device acoustic signature corresponding to the current support configuration;
obtaining at each acoustic sensing element of the plurality of acoustic sensing elements a measured acoustic response corresponding to the input, resulting in measured acoustic responses for the input; and
determining the location of the input based on the measured acoustic responses and the selected device acoustic signature for the current support configuration.
