|A digital pen is an input device which captures the handwriting or brush strokes of a user, converts handwritten analog information created using "pen and paper" into digital data, enabling the data to be utilized in various applications. For example, the writing data can be digitized and uploaded to a computer and displayed on its monitor. The data can then be interpreted by handwriting software (OCR) and used in different applications or just as graphics.
A digital pen is generally larger and has more features than a stylus. Digital pens typically contain internal electronics, and have features such as touch sensitivity, input buttons, memory, writing data transmission capabilities, and electronic erasers.
