Abstract

We demonstrate a standalone digital pen that writes on regular paper by tracking the writing nib’s absolute position in paper coordinates. The pen writes like a regular pen, but simultaneously captures handwritten information digitally with the aid of a Navigation Engine mounted atop the pen. The Navigation Engine has a wide-field-of-view vision system with a single-viewpoint catadioptric lens for observing the environment as the pen writes. A processor belonging to the Navigation Engine applies computationally efficient navigation algorithms to a stream of images of the pen’s environment to capture the pen’s full movement. The resultant data stream including x-y position of the nib and the pen’s Euler angles facilitate application of this technology to a wide range of tasks. In contrast to all other known digital pen technologies, this pen not only functions like a regular pen, but also provides an electronic copy of the digital writing without using any special paper.
