About adjusting finger space when doing WHLK test

Question

Hi Microsoft Team,

I am studying the HLK test for my class project. When I doing WHLK five contacts test to study the touch digitizer jitter, can I try to increase the space of Finger Jigs to let the test pass? Because when I put the 5 contacts on the green circles, sometimes it can directly pass and sometimes can't . So I am considering properly increase the space of finger to let the test pass, maybe has 3% to 10% offset, and the after adjusting the space of fingers, the test can pass also. So I am wondering is adjusting finger space to pass the test is acceptable?

Thanks.

Hello

When conducting the WHLK five contacts test to study touch digitizer jitter, it is important to adhere to the specified test parameters to ensure accurate and reliable results. The test is designed to measure the jitter characteristics of a Windows Touchscreen device, and any deviation from the standard procedure could affect the validity of the results.

 

According to the information available, the test examines jitter during static contact, linear motion, and radial motion, and it verifies that the jitter specification is respected. Adjusting the space of the Finger Jigs to pass the test, even with a 3% to 10% offset, may not be acceptable as it could lead to inaccurate results and fail to meet the test's intended purpose.

 

For more detailed guidance, you can refer to the official documentation on the Windows Touch Digitizer Jitter Test - Five Contacts.
