Additional documentation

Tests in this feature area might have additional documentation, including prerequisites, setup, and troubleshooting information, that can be found in the following topic(s):

Running the test

Before you run the test, complete the test setup as described in the test requirements: Mouse or other Pointing Device Testing Prerequisites.

This test requires very precise movement in a straight line. We recommend that you perform this test by using a precision rig or other precision device that is capable of straight line movement without any jitter.

  1. Place two precision contacts slightly outside the top left corner of the touchpad.

  2. Drag that contact in a straight line from the top left to the bottom right corner of the touchpad.

  3. Drag the contact from the bottom right up to the top left.

  4. Repeat this pattern for a total of five iterations.

Troubleshooting

Error Description/Workaround

[15] contact didn't move in straight line

Reported path strayed varied from a straight line by more than the allowed tolerance.

[14] packet too far from edge: ###

  • Swipe must start at or before the edge.

  • Swipe must go all the way to the opposite edge. Performing swipe too quickly might not allow the device to fully report.
