Stylus-related refers to topics and technologies connected with the use of a stylus on touch-sensitive devices. A stylus is a pen-shaped input tool that can simulate handwriting, drawing, and precise selection, used with tablets, smartphones, and hybrid laptops. The term encompasses hardware designs, input protocols, software support, and the practical workflows enabled by stylus use.

Styluses vary in capability and technology. Passive styli rely on the touchscreen’s electric field and offer basic pointing without power. Active styli include electronics for pressure sensitivity, tilt sensing, and wireless communication. Common technologies include Wacom's EMR and AES, Apple Pencil interfaces, Microsoft Pen Protocol, and the cross‑device USI standard that aims for interoperability across manufacturers.

Applications cover graphic design, digital note taking, education, engineering, and accessibility. Pressure and tilt data allow shading and line variation in art programs, while high precision and palm rejection improve handwriting and annotation on documents. Stylus support often determines the efficiency of workflows in creative and professional software.

Compatibility varies by platform. Some devices support proprietary stylus ecosystems with optimized latency and features, while others adopt open standards for broader interoperability. Software and driver updates can be required to enable full functionality.

Current trends emphasize lower latency, better palm rejection, longer battery life for active styli, and more accurate pressure and tilt sensing. As devices converge, standards like USI promote cross‑device use, but many ecosystems still favor vendor-specific styluses for optimal performance.
