Testing user interface functionality through actuation by a piezoelectric grid

A control system to facilitate testing user-selectable functions on a user interface of a computing device, wherein a piezoelectric grid comprising piezoelectric material that deforms upon application of electricity is installed onto a surface of the user interface of the computing device, the control system comprising:

• one or more computer-readable storage media;
• a processing system operatively coupled with the one or more computer-readable storage media;
• and
• program instructions stored on the one or more computer-readable storage media that, when read and executed by the processing system, direct the processing system to:
• generate a control mapping of areas of the piezoelectric grid to locations on the user interface of the computing device;
• receive test instructions comprising actuation information for a targeted portion of the user interface of the computing device;
• process the test instructions and the control mapping to determine control signals for the piezoelectric grid to implement the test instructions;
• and
• transmit the control signals to the piezoelectric grid to actuate the targeted portion of the user interface of the computing device.
