A 20-year-old HCI paper, resurrected as a Chrome extension

Short summary

A developer resurrected the 2005 Bubble Cursor HCI research by building MagPoint, a Chrome extension that dynamically sizes cursor hit areas to the nearest clickable element, preventing mis-clicks on dense UIs. Using Voronoi cell geometry and point-to-rectangle distance calculations, the extension reproduces HCI research showing measurable interaction speedups. The implementation features fluid visual feedback and carefully preserves normal text-selection behavior.
