Stylus

A pen-shaped input device used to interact with touchscreens, tablets, and other digitizer surfaces. Unlike finger touch, styluses provide a smaller contact point for precise selection, and active styluses can detect pressure, tilt, and hover states. For accessibility, styluses can benefit users who have difficulty with the fine motor control required for multi-touch gestures, those who need a grip aid or larger implement to hold, and users whose fingers may not reliably register on capacitive touchscreens. Styluses are also valuable for people who find direct touch fatiguing over extended use or who need to see the screen without hand occlusion.
