Mouse, Trackpad, and Touchscreen Test

Overview

This comprehensive input test evaluates the functionality of all pointer devices including mouse, trackpad, touchscreen, and stylus input. The test provides real-time visual feedback in a fullscreen canvas environment, supporting multiple simultaneous inputs and advanced features like the Ink API for stylus devices.

The test tracks multiple input types simultaneously, measures scroll precision, supports multi-touch gestures, and provides visual feedback for all input methods. It includes fallback modes for devices without native fullscreen support and prevents interference from browser gestures like pinch-zoom.
