Stylus testing system

摘要

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.

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; anddetermine 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; andreceive 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.
