Stylus testing system
First Claim
Patent Images
1. A system for automated testing of a stylus, the system comprising:
- a holder to receive the stylus;
a detector to detect that the stylus is disposed in the holder;
an actuator to move the holder;
a touch panel to generate position data for a plurality of points of contact between the stylus and a surface of the touch panel; and
a processing device coupled to the detector, the touch panel and the actuator, the processing device to;
receive a detector signal from the detector indicating that the stylus is disposed in the holder;
in response to receiving the detector signal, send a first actuator signal to the actuator to move the holder and the stylus across the surface of the touch panel along a linear path;
receive position data from the touch panel for the plurality of points of contact between the stylus and the touch panel along the linear path; and
determine that the position data corresponds to the linear path created by the actuator; and
a mass fixture including one or more masses that are attachable to at least one of the holder or the stylus, wherein the processing device is further to;
send a second actuator signal to the actuator to position the stylus beneath the mass fixture;
send a mass fixture signal to the mass fixture to place the one or more masses onto the stylus; and
receive pressure data from the touch panel indicative of a pressure applied by the stylus to the touch panel responsive to the one or more masses.

Abstract
Systems and methods for testing a stylus are described. A processing device determines that a stylus is disposed in a holder above a touch panel that generates position data for each point of contact between the stylus and the touch panel. In response to such determination, the processing device performs one or more tests of the stylus. The processing device may cause the holder to move the across the surface of the touch panel, receive position data, and compare the position data to reference data to determine operation of the stylus.

4. A method comprising:
-
determining, by a processing device, that a stylus is disposed in a holder, wherein the stylus is positioned above a touch panel that generates position data for a plurality of points of contact between the stylus and the touch panel; causing, by the processing device, the holder to move the stylus across a surface of the touch; receiving, by the processing device, the position data for the plurality of points of contact between the stylus and the touch panel; comparing, by the processing device, the position data to reference data to determine operation of the stylus; wherein determining that the stylus is disposed in the holder includes determining that the stylus is disposed in a conductive holder with an active tip in contact with the touch panel; sending a first signal to an actuator to move the stylus beneath a mass fixture; sending a second signal to the mass fixture to place one or more masses onto the stylus; and receiving, from the touch panel, pressure data generated by the stylus from the touch panel indicative of a pressure applied by the stylus to the touch panel with the one or more masses on the stylus. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11)

12. A non-transitory computer-readable medium having instruction encoded thereon which, when executed by a processing device, cause the processing device to perform operations comprising:
-
reading, by the processing device, a script; and executing, by the processing device, the script to perform one or more tests of a stylus, wherein performing the one or more tests comprises; determining that the stylus is disposed in a holder above a touch panel that generates position data for a plurality of points of contact between the stylus and the touch panel; sending a signal to one or more actuators to move the stylus across a surface of the touch panel; receiving, from the touch panel, at least one of data generated by the touch panel or data generated by the stylus; comparing the at least one of the data generated by the touch panel or the data generated by the stylus to reference data to determine operation of the stylus; wherein determining that the stylus is disposed in the holder includes determining that the stylus is disposed in a conductive holder with an active tip in contact with the touch panel; sending a first signal to an actuator to move the stylus beneath a mass fixture; sending a second signal to the mass fixture to place one or more masses onto the stylus; and receiving, from the touch panel, pressure data generated by the stylus from the touch panel indicative of a pressure applied by the stylus to the touch panel with the one or more masses on the stylus. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
