Baseline test criteria for Windows 8 touchpads

Updated: October 12, 2012

To ensure high quality and consistency among devices, it is important to confirm that your touchpad’s features and functionality conform to the specified Windows 8 design recommendations. This topic summarizes the baseline test criteria.

This information applies to the following operating system:

  • Windows 8

Functional recommendation summary

  • All Windows 8 touchpads that meet the minimum size recommendations (90mm (w) x 55mm (h)) should support two-finger pinch gesture for zoom and single-finger swipe gestures for the keyboard shortcuts as specified in Swipe in from the edges.
  • All Windows 8 touchpads should support standard mouse functionality with integrated primary and secondary buttons. The primary button click can be simulated by a tap gesture on the touchpad screen.
  • All Windows 8 touchpads should support the two-finger slide gesture to simulate both the vertical and horizontal scroll wheels. The scroll wheel simulation should meet the design criteria as specified in Two-finger slide and pinch gestures for high-resolution mouse wheel and High-resolution mouse wheel.
  • All Windows 8 touchpads should support the two-finger pinch gesture to simulate the vertical mouse wheel with the Ctrl key held down. The scroll wheel simulation should meet the design criteria as specified in Two-finger slide and pinch gestures for high-resolution mouse wheel and High-resolution mouse wheel.
  • A Windows 8 touchpad should not assign alternative gestures to engage other Windows shortcut keys.

Baseline test criteria

The following table lists the minimum test criteria for the baseline design recommendations. For better quality, incorporate the additional details that are described in this topic set.

ScenarioExpected results
(Basic mouse functionality) Move mouse pointer using touchpad The mouse pointer should move across the desktop without interference by accidental or unintended touchpad gestures.
(Basic mouse functionality) Tap anywhere on the touchpad to click the desktop The primary button click should happen where the mouse cursor was just before the tap gesture
(Basic mouse functionality) Click on the primary or secondary (physical) button on the touchpad A click action for the primary button. A context menu (desktop), selection of tile (Start screen), or app commands (Windows Store app) for a secondary button click.
Two-finger slide gesture (horizontal direction) on the touchpad while the system focus is on Windows 8 Start screenThe Windows 8 Start screen should scroll in the direction of the fingers that are traveling on the touchpad surface. No animation gaps should occur as the finger slides across the touchpad.
Two-finger flick gesture (horizontal direction) on the touchpad while the system focus is on the Windows 8 Start screenThe Windows 8 Start screen should scroll horizontally with inertia. No animation gaps should occur as the finger slides across the touchpad or transitions to the inertia phase.
Two-finger slide gesture (vertical direction) on the touchpad while the system focus is on the Windows Internet Explorer content (such as www.msn.com)The browser content should scroll vertically in the direction of the finger traveling on the touchpad surface. No animation gaps should occur as the finger slides across the touchpad.
Two-finger flick gesture (vertical direction) on the touchpad while the system focus is on the Internet Explorer content (such as www.msn.com)The browser content should scroll vertically with inertia. No animation gaps should occur as the finger slides across the touchpad or transitions to the inertia phase.
(For touchpads larger than 90mm x 55mm) Two-finger pinch gesture on the touchpad while the system focus is on the Windows 8 Start screen The Start screen should zoom in or out corresponding to the pinch gesture.
(For touchpads larger than 90mm x 55mm) A single-finger swipe from the right edge of the touchpad Open or close charm.
(For touchpads larger than 90mm x 55mm) A single-finger swipe from the top edge of the touchpad with Internet Explorer 10 open Open or close the app commands for Internet Explorer 10.
(For touchpads larger than 90mm x 55mm) Launch multiple Windows Store apps, and then run a single-finger swipe on the left edge of the touchpad Flip to the last app.
