In this paper, we describe the design of menus for multi-user digital tabletops. On direct input surfaces, occlusions created by the user's hand decrease interaction performance with menus. The key design criteria are to avoid these occlusions and to adapt the menu placement to the user's handedness and position on the tabletop. We present an adaptive menu(More)
FLUX is an interactive touch-sensitive tilting surface that can be used either as a sketching board, as an interactive discussion table, and as a digital presentation whiteboard. The surface, based on a rear-projection screen, supports both multi-touch interaction as well as multiple pen interaction with individual identification of each pen. Our setup(More)
In this paper we describe the process that we undertook to build a configurable wireless platform that can be used to implement cognitive radio network (CRN) architectures. Consisting of a commodity IEEE 802.11 a/b/g (WiFi) router at the physical (PHY) layer and RF signal processing and IP traffic shaping circuitry, the resultant hybrid terminal (called the(More)
