1. A method comprising:

  • adjusting ground of a conductor that is external to a touchscreen device effective to obtain repeatable measurements, the conductor having a defined contact geometry that is consistent;

    positioning the conductor as proximal to the touchscreen device, the conductor in a non-grounded state; and

    testing the defined contact geometry of the conductor contacting the touchscreen device using data generated by the touchscreen device in order to test and differentiate between a light touch input and a hard touch input, said testing comprises using an electrical switch to alternate the conductor between a grounded state to emulate a touch event and the non-grounded state to emulate a non-touch event on the touchscreen device without moving the conductor subsequent to said positioning the conductor.
