LongPen

The LongPen is a remote signing device that allows a user to produce a signature on a physical document from a distant location. It was invented by writer Margaret Atwood in 2004 and debuted in 2006. It allows a person to write remotely in ink anywhere connected to the Internet, via a touchscreen device operating a robotic hand. The system also supports a live audio and video connection between the signer and the receiving location.
