level of detail. Further, jointly viewing of content such as photos is limited to a small number of users. In contrast, users find large displays in their environments yet cannot make use of them by exploiting the available screen space. For instance, public displays at airports or train stations, TV sets, or information kiosks can be found in many situations and users’ environments. In this paper, we present an approach which allows users to establish an ad-hoc connection between their mobile devices and external A large body of related work addresses the challenge of integrating mobile devices into existing device infrastructures in order to facilitate the interaction. For instance, Rekimoto and Saitoh investigated hyper dragging for seamless interaction across multiple devices [5]. Hinckley et al. present stitching, which allows users to connect multiple tablet PCs to create a larger logical screen and to transfer data between the devices [2]. Lucero et al. investigated how multiple mobile phones can be integrated in order to create a shared screen [3]. In contrast to the MobIES, their approach is
