In computing, a stylus (or stylus pen) is a small pen-shaped instrument that is used to input commands to a computer screen or mobile device. The user places the stylus on the surface of the screen to draw or make selections by tapping the stylus on the screen.[1]
Pen-like input devices which are larger than a stylus, and offer increased functionality such as programmable buttons, pressure sensitivity and electronic erasers, are often known as digital pens.[1]
The stylus is the primary input device for personal digital assistants.[1] It is also used on the Nintendo DS game console.[2] Some smartphones, such as Windows phones, require a stylus for accurate input.[3] However, devices featuring multi-touch finger-input are becoming more popular than stylus-driven devices in the smartphone market.[4]
The first use of a stylus pen in a computing device was the Styalator, demonstrated by Tom Dimond in 1957.[5]
