The LongPen is a remote signing device conceived of by writer Margaret Atwood in 2004 and debuted in 2006. It allows a person to remotely write in ink anywhere in the world via tablet PC and the Internet and a robotic hand. It also allows for an audio and video conversation between the endpoints, such as a fan and author, while a book is being signed.
