In this paper we present a Focus+Context screen for combined pen and touch interaction. A tabletop display presents contextual information and enables multi-touch detection for navigation through frustrated total internal reflection (FTIR). A high resolution pen enabled display is continuously localized on the tabletop. It is used as a movable focus display and pen input device. The resulting system has a large virtual resolution for both display and pen interaction. We demonstrate the advantages of Focus+Context for pen-based interaction in combination with multi-touch navigation in applications that make use of sketch-based interfaces.
