Greater Than Maximum Supported Contacts

  • Article

Test name

Test.GreaterMaxContacts.json

Core requirements tested

Device.Input.PrecisionTouchpad.Reliability.ContactSuppression

Test purpose

Verifies that the device has consistent behavior when the maximum number of supported contacts is exceeded on the digitizer surface.

Tools required

PTLogo.exe

Validation steps

  1. Start Test.GreaterMaxContacts.json.

  2. Following the instructions on the screen, place a number of fingers on the touchpad equal to the supported maximum contacts, with at least 14mm between each. These contacts should be visualized in PTLogo.

    • Move contacts around slightly, so it is clear that they are being continuously reported.

    • If the device does not report all contacts, manually fail the test.

  3. Place one additional contact on the digitizer surface.

  4. Verify that as soon as this finger comes down, all contacts should be automatically lifted (reporting ceases), so that all visualization in PTLogo stops.

  5. Lift each finger, one at a time. Verify that no contact reporting occurs.

    Note  

    Button state reporting may or may not occur, and bears no relevance to the test.

     

  6. After all contacts have lifted, again place the maximum number of contacts on the digitizer surface, and verify that they are reported.

  7. Manually pass the iteration if all these conditions have been met; otherwise manually fail the iteration.

Common errors

None

Passing

1/1 (100%) iterations must pass in order to complete with passing status.
