" summary

Claims Pointer Events is a W3C candidate recommendation that replaces mouse events with a unified model handling touch pen and mouse with attributes like pointerId and width/height and sensors for pressure/tilt. Research shows 7–9 mm (≈40–50 px) is the touch sweet spot and 65–85% of sites violate target-size guidance. Demos include a canvas finger‑painting app using pointerid to disambiguate streams and event.width/height to vary stroke. Implementations exist in IE10 (prefixed) IE11 (unprefixed) and polyfills hand.js and points.js.
