The STABILO Digipen: A sensor-equipped ballpoint pen with wireless connectivity.
We develop and build digital writing instruments in Heroldsberg, Germany. Our main product, the STABILO DigiPen, is equipped with five sensors and has internal data processing capabilities. It writes on normal paper.
Currently, there are two versions available for purchase: The EduPen and the ErgoPen.
For researchers, we published a benchmark dataset and the Digipen Development Kit.
