Noise Suppression

  • Artykuł

This is to test the ability of a Windows Touchscreen device to suppress invalid input (noise) that could otherwise be mistaken as touch input.

Test name

NoiseSuppression.json Associated compatibility requirements

Device.Input.Digitizer.Base.ContactReports Test purpose

Verifies that a Windows Touchscreen device does not report data for locations where touch input does not occur. Tools required

PT3 Running the test

This test can help to ensure that touch systems can effectively tolerate common environmental conditions.

This test presents two scenarios: the only distinction between the two scenarios is the power source. For the Battery portion of the test, you should remove the external power source from a mobile system. For AIOs and external monitors, perform the test with AC power. In each case, the test validates that a contact that is held at the minimum required distance from the screen does not register any touch contacts.
