Digitizer Jitter
This is to test the jitter characteristics of a Windows Touchscreen device (or digitizer).
Test name
- DigitizerJitterOneContact.json
- DigitizerJitterFiveContacts.json
Associated compatibility requirements
Device.Input.Digitizer.Touch.Jitter Test purpose
Verifies that a Windows Touchscreen device does not exceed the allowable amount of jitter – moving and stationary. Tools required
PT3 Running the test
Clean input is important throughout the system and across applications. Whether a user is performing a hold gesture to learn more about a user interface (UI) element, playing a game, or holding a key on the software keyboard, this fidelity allows software to correctly interpret a user's intention and provide an optimal touch experience.
This test presents twelve distinct scenarios that examine jitter during static contact and linear motion. Most of these interactions require the use of assistive technology.
