Digital pen

A digital pen is an input device which captures the handwriting or brush strokes of a user and converts handwritten analog information created using "pen and paper" into digital data, enabling the data to be utilized in various applications. This type of pen is usually used in conjunction with a digital notebook, although the data can also be used for different applications or simply as a graphic.

Microsoft Surface Pen is a digital pen.

Smart pen is a more especific than a digital pen, this one satisfies the same basic characteristics, but also have other like voice recording or text scanner.

A smart pen is generally larger and has more features than an active pen. Digital pens typically contain internal electronics and have features such as touch sensitivity, input buttons, memory for storing handwriting data and transmission capabilities.[1]

Characteristics
Smart Pen

The input device captures the handwriting data, that, once digitized, can be uploaded to a computer and displayed on its monitor.

Some pens are equipped with a digital recording device that allows users to use them as intelligent Dictaphone. They can be used, for example for students to record the voice of the master while taking notes.

Active
Active pens, such as N-trig's DuoSense Pen™, include electronic components whose signals are picked up by a mobile device's built-in digitizer and transmitted to its controller, providing data on pen location, pressure, button presses and other functionality.

Positional
Position-based digital pens use a facility to detect the location of the tip during writing. Some models can be found on graphics tablets made popular by Wacom, and on tablet computers using Wacom's Penabled™ technology.

Camera
Camera-based pens use special digital paper to detect where the stylus contacts the writing surface, such as those using Anoto technology or NeoLAB Convergence technology.

Trackball pen
Trackball pens use a sensor that is located on the pen to detect the motion of the trackball.
