How to use Multi-Touch Test

  1. Open Multi-Touch Test on the same browser and device you want to diagnose.
  2. Touch pages use browser pointer and touch events exposed by the device.
  3. Run the visible touchscreen test controls and watch the live result area update before judging the hardware.
  4. Repeat the test once or twice, then compare related InputLab tools if the touchscreen behavior looks inconsistent.

How to read the result

Multi-Touch Test is most useful when you read the result as a practical browser diagnostic. Screen protector thickness, hand position, browser gestures, and OS touch filtering can affect contact data. A repeated pattern across multiple runs is more meaningful than one isolated spike, missed event, or visual artifact.

Privacy and permissions

Touch pages use browser pointer and touch events exposed by the device. Tests are designed to run locally in the browser, with permissions controlled by the browser.
