DeltaPen: A Device with Integrated High-Precision Translation and Rotation Sensing on Passive Surfaces

We present DeltaPen, a pen device that operates on passive surfaces without the need for external tracking systems or active sensing surfaces. DeltaPen integrates two adjacent lens-less optical flow sensors at its tip, from which it reconstructs accurate directional motion as well as yaw rotation. DeltaPen also suppor…
