![]() ![]() Before you run this test, we recommend that you review Windows Hardware Certification Requirements and the HID Validator documentation that is installed together with the HID Validator tool. The Windows Hardware Lab Kit (Windows HLK) includes the HID Validator tool. To run this test, the HID descriptor must be stored in the device firmware. The WTTL does not make allowances for devices that report physical size values that differ from the true measurement by more than 2mm. The test will be affected by errors for example, targets that are intended to be 20mm apart might resolve to being 22mm apart. The test itself relies on this information to size elements appropriately. We strongly recommend that you use the dimensions that are specified by the display manufacturer. Discrepancies affect system gestures and UI elements, which rely on physical size information. This test verifies that the physical dimensions that are reported by the HID descriptor match the true physical dimensions of the visible screen area. For example, the momentum of a touch gesture depends on the physical distance moved and the length of that movement. The physical dimensions of the device must support system gestures and general touch interactions (). FFU is required.įor a Tablet device, ensure that the bezel is flush with the display (the bezel must not be taller than the display). ![]() USB and I2C buses are required because they support the HID standard upon which the Windows touch infrastructure is based. It also provides an optimal set of conditions to use the thumb keyboard. The bezel requirement (.Bezel) helps ensure easy access to the edge of the screen, which is used to display the Charms Bar and to switch applications. (The HID Validator tool installed together with the Windows HLK). Measured requirements include: having a bezel that is flush with the display, specifying physical dimensions that match the device's true physical dimensions, and passing the HID Validator tool's static test. The Windows Touch Test combines a set of simple manual tests. Tests in this feature area might have additional documentation, including prerequisites, setup, and troubleshooting information, that can be found in the following topic(s):īefore you run the test, complete the test setup as described in the test requirements: Windows Touch Testing Prerequisites.
