The earliest computer-related usage for a stylus was in 1643 with
Pascal's calculator.[4] The device had rotary dials that rotated in accordance with the selected numbers; with gears, drums, and clever engineering, it was capable of addition, subtraction, multiplication and division (using 9's constant). A stylus was used to turn the dials.
Later devices of this type include the
Arithmometer, in the 1860s; and the
Addiator, in 1920.[5] The Addiator was a pocket mechanical adding machine that used a stylus to move tiny rigid slices of sheet-metal that were enclosed in a case. On the side of a slice of metal there were numbers that became visible to display the result. It was capable of addition, subtraction, multiplication and division. In 1967 there was a HEXADAT model,[6] which allowed 4-function math to be applied to hexadecimal numbers for use in programming. The first use of a stylus in an electronic computing device was the Stylator, demonstrated by Tom Dimond in 1957.[7][8]
Capacitive (also called passive) styluses emulate a finger by using a tip made of rubber or
conductive foam; or metal such as copper. They do not need to be powered and can be used on any
multi-touch surface that a finger can be used, typically
capacitive screens that are common in
smart phones and
tablet computers. Stylus tips made of rubber or foam are often large, making it rather difficult to get precise notes or drawings.
Capacitive styluses work by distorting the screen’s electrostatic field.[10] Screens that receive input from a capacitive stylus (as well as human fingers) can't register pressure applied by the pen; tilting of the pen; and can't distinguish between a capacitive stylus, your finger, or a resting palm as input - it will register all of these touches as marks on the screen.
Capacitive styluses are made of a conductive material (typically as a metal rod or barrel) to transmit electrical charge between the hand and a rubber/foam[11][better source needed] or metal tip such as copper. Being free of any digital components, capacitive styluses can be cost effective to manufacture.
DIY capacitive styluses can also be made with materials found at home.[12]
Capacitive styluses tend to work on any
multi-touch surface that accepts input from a finger.
Active (also called
digital[1]) styluses include digital components or circuitry inside the pen that communicates with a digitizer on the touch device. This communication allows for advanced features such as pressure sensitivity, tilt, programmable buttons, palm detection, eraser tips, memorizing settings, and writing data transmission. In order for an active stylus to function, its digital component protocol must match the digitizer technology in the touch screen it is interacting with. Active styluses are powered by a removable or chargeable battery, or operate passively by inductance.
Active styluses use different protocols by different manufacturers in order to communicate with the digitizer of a
graphic tablet or
multi-touch device. The digital protocol of the pen must match the device digitizer, otherwise input from the pen will not register on the device.
A stylus' performance is measured by these four characteristics:[13]
Comfort
Resistance
Balance and weight
Precision:
Responsiveness & speed
Jitter
Tilt
Levels of pressure
Palm rejection or detection,[14] which prevents a touch device from registering or marking the screen when a hand or palm is resting on the screen surface, relies on a combination of technology in the stylus, the OS software and the screen digitizer technology, to work effectively.

Smartphone stylus pens have become a popular tool for smartphone users who want to take notes, draw, or create digital art on their device. A good stylus can make a huge difference in the precision and ease of use when interacting with a smartphone, especially for those who find it difficult to navigate the small touchscreen with their fingers.
