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.

Abstract
Touchscreen testing techniques are described. In one or more implementations, a piece of conductor (e.g., metal) is positioned as proximal to a touchscreen device and the touchscreen device is tested by simulating a touch of a user. This technique may be utilized to perform a variety of different testing of a touchscreen device, such as to test latency and probabilistic latency. Additional techniques are also described including contact geometry testing techniques.

11. A method comprising:
-
adjusting ground of a plurality of conductors that are external to a touchscreen device effective to obtain repeatable measurements, each of the conductors being an electrically conductive metal having a defined contact geometry that is consistent and having a size that is different, one to another; positioning the plurality of conductors as proximal to the touchscreen device; gathering data from the touchscreen device that describes the contacting of the plurality of conductors as a touch event and a non-touch event; and testing the defined contact geometry of the conductor contacting the touchscreen device using the gathered data, in order to test and differentiate between a light touch input and a hard touch input, by using an electrical switch to alternate each of the plurality of conductors between a grounded state to emulate the touch event on the touchscreen device for each of the plurality of conductors and a non-grounded state to emulate the non-touch event on the touchscreen device for each of the plurality of conductors, said testing without moving the plurality of conductors subsequent to said positioning the plurality of conductors. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A system comprising:
-
a conductor implemented to adjust ground of the conductor that is external to a touchscreen device effective to obtain repeatable measurements, the conductor being an electrically conductive metal having a defined geometry that does not change with a variable amount of pressure used to contact the touchscreen device, the conductor positioned proximal to the touchscreen device and implemented to move across a surface while contacting the touchscreen device; an electric switch configured to alternate the conductor between a grounded state and a non-grounded state; and a test module of a computing device configured to place the conductor against the touchscreen device for testing centroid detection of the touchscreen device using data generated by the touchscreen device responsive to the conductor being moved across the surface of the touchscreen device, the test module connected to the electric switch and further configured to; communicate a command to the electric switch to place the conductor in the grounded state to emulate a touch event on the touchscreen device while the conductor is contacting the touchscreen device; and communicate another command to the electric switch to place the conductor in the non-grounded state to emulate a non-touch event on the touchscreen device while the conductor is contacting the touchscreen device. - View Dependent Claims (20)
