A pen with a camera that records what you write on ordinary paper. The invention is the camera’s wide field of view: at least 90 degrees, and for example about 125. That way the pen keeps seeing the page across almost any angle you hold it at, and can turn your handwriting into data.
Invented with Shubham Koyal, Cas Kempers, Franciszek Paweł Szewczyk, Breno Cunha Queiroz, Riordan Maduro and Vishal Raveendranathan. Priority date 29 September 2022.
