Stylus
A pen-shaped instrument used with graphics tablets or touch screen input devices to write or draw on the computer screen, similar to a sheet of paper. Unlike a pen the
Stylus has a simple plastic tip and is often smaller to help fit in a compartment the device is used with.
In the picture to the right, is an example of a Stylus, the
Palm Z22 Stylus.
Today, the Stylus is not commonly found or used with devices designed as they've been mostly been replaced with touch screens that allow the user to navigate using their finger. A good example of a device using this well is the Apple iPhone.
