Updated: 10/17/2017 by Computer Hope
A pen computer is a handheld computer, or PDA (personal digital assistant), that the user interacts with using a pen device (called a stylus) instead of a keyboard. Pen computers require the user to draw symbols that represent characters called graffiti. Today, pen computing is mostly replaced by touch computing, with devices like the Apple iPhone that allow navigation and input using a finger.
