Digital pens are advanced writing instruments that capture handwritten notes and drawings digitally. They often use special paper or surfaces that can detect the pen's movements, allowing users to write naturally while the pen records their input. This technology is beneficial for students, professionals, and artists who want to combine the tactile experience of writing with the convenience of digital storage. These pens typically connect to devices like tablets or computers via Bluetooth or USB, enabling easy transfer of notes and sketches. Some models even include features like pressure sensitivity and customizable buttons, enhancing the user experience for various applications, from note-taking to digital art.
