A smartpen or smartpen is an input device that captures a user’s handwriting or brushstrokes and converts handwritten analog information created in “pen and paper” into digital data, enabling the use of data in various applications. This type of pencil is usually used with a digital laptop, although the data can also be used for different applications or simply as a graph. A digital pen is usually larger and has more features than an active pen. Digital pens typically contain internal electronic components and have features such as touch sensitivity, input buttons, memory for storing handwritten data, and transmission capabilities.
The input device captures the handwriting data that, once scanned, can be downloaded to a computer and displayed on its monitor. Some pens are equipped with a digital recording device that allows users to use them as a smart dictaphone. They can be used, for example, so that students can record the teacher’s voice while taking notes.
: Accelerometer-based digital pens contain components that detect pen movement and contact with the writing surface.
Active pens, such as N-trig’s DuoSense Pen ™, include electronic components whose signals are picked up by the built-in scanner of a mobile device and transmitted to its controller, providing data on the location of the pen, pressure, buttons and other features.
: Position-based digital pens use a function to detect the location of the tip during writing. Some models can be found on graphic tablets popularized by Wacom, and on tablets using Wacom’s Penactive ™ technology.
: Camera-based pens use special digital paper to detect where the stylus comes into contact with the writing surface, such as those using Anoto technology.
: Trackball pens use a sensor located on the pen to detect the movement of the trackball.
