The LongPen is a remote signing device conceived of by writer Margaret Atwood in 2004 and debuted in 2006.[1] It allows a person to write remotely in ink anywhere in the world via tablet PC and the Internet and a robotic hand.[2] It also supports an audio and video conversation between the endpoints, such as a fan and author, while a book is being signed.
The system was used by Conrad Black, who was under arrest, to "attend" a book signing event without leaving his home.[2]
