1. A method for determining location of an input on a surface of a device using a plurality of acoustic sensing elements, the method comprising:

  • determining a current support configuration of the device;

    selecting a device acoustic signature corresponding to the current support configuration;

    obtaining measured acoustic response corresponding to the input at each acoustic sensing element of the plurality of acoustic sensing elements, 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.
