On most electronic paper displays (EPDs), low update rates lead to a poor user experience especially for pen‐based markups. The slow update causes a remarkable delay between pen motion and visibility of the stroke. Even worse, this delay varies depending on the current part of the update cycle. This paper presents a real‐time pen tracking method for EPDs, using a new display driver on an unmodified E Ink hardware platform. This method compares favorably to the iLiad E‐Reader.
