An electronic notepad, also known as digital notepad or portable digital notepad (PDN), is a device that stores penstrokes drawn across its surface as digital images to be later transferred to a computer. The user typically places a regular sheet of paper on the notepad surface and writes on it with a special ink pen or stylus. Any notes or sketches thus produced are stored in the device's memory exactly as they appear on the piece of paper. Once transferred to a computer, handwritten notes may be converted to text using handwriting recognition software. Unlike digitizing tablets an electronic notepad is not an input/pointing device for a computer. Nor does it have a view screen like a tablet pc.
