Abstract
Example apparatus and methods concern automated testing of a capacitive touch interface (e.g., touch screen). One example apparatus includes probes that extend and retract from the apparatus under programmatic control. The probes produce a capacitive touch response on a capacitive touch interface. The example apparatus includes logics configured to control touch testing of the interface using the probes. A first logic may provide a closed loop vision system for controlling the position of the interface relative to the apparatus. A second logic may calibrate a co-ordinate system associated with the apparatus and a co-ordinate system associated with the interface so that the apparatus may function in the pixel space of the interface being tested. A third logic may control the probes to test the interface by producing a series of touches, multi-touches, or gestures on the interface.
