What this test checks and why it matters.
This test uses the Web Touch API to detect and track touch inputs in real time. Each touch point is rendered as a circle with its X/Y coordinates. Dragging draws a continuous trail, which makes it easy to spot areas where tracking drops out or becomes inaccurate.
Multi-touch capability matters for gaming (pinch-to-zoom, dual-stick controls), drawing apps, and music production software. The maximum simultaneous touch count is determined by your device's digitizer hardware, not the browser or operating system.
