Media façades are one prominent example of how new technologies currently augment urban spaces. At the same time, they offer new, ubiquitous opportunities for novel applications. To achieve a usable and enjoyable outcome, however, designing interaction with media façades demands a structured design process. In this paper, we present our(More)
Smartphone users might be interrupted while interacting with an application, either by intended or unintended circumstances. In this paper, we report on a large-scale observational study that investigated mobile application interruptions in two scenarios: (1) intended back and forth switching between applications and (2) unintended interruptions caused by(More)
Designing interactions with media façades bears several challenges. One of them arises when multiple users are interacting with a media façade simultaneously. In this work we report on our experiences designing a mobile multi-user interaction system with a high-resolution back projection media façade in a public space (see Figure 1, middle).(More)
between serum and heparin-treated plasma. Thus, sodium citrate-and EDTA-treated samples may yield more accurate values for cystine. In summary, the anticoagulant used in sample preparation may markedly affect the results of amino acid analysis by automated ion exchange chromatography. Sample preparation should be standardized, and clini-cians should be(More)
The increasing number of media facades in urban spaces offers great potential for new forms of interaction especially for collaborative multi-user scenarios. In this paper, we present a way to directly interact with them through live video on mobile devices. We extend the Touch Projector interface to accommodate multiple users by showing individual content(More)
The search for a certain book in a library that contains many books can be a time-consuming task. Even if one finds the right shelf, one still has to browse an often huge area in the shelf. The same problem occurs when searching for a specific product in a supermarket shelf that fits one personal preferences (e.g. a allergic or diet profile). With(More)
The electronic market has rapidly grown in the last few years. However, despite this success, consumers still enjoy visiting a "real store with real products". Therefore various common technologies have been installed in supermarkets to support the customer's shopping process and experience. In this paper, we introduce the <i>IRL SmartCart</i> - an(More)
Mobile phones have evolved significantly in recent years from single-purpose communication devices to multi-purpose computing devices. Despite this evolution, the interaction model for how incoming calls are handled has barely changed. Current-generation smartphones still use abrupt full-screen notifications to alert users to incoming calls, demanding a(More)
Digital technologies are rapidly finding their way into urban spaces. One prominent example is media fa&#231;ades. Due to their size, visibility and their technical capabilities, they offer great potential for interaction and for becoming the future displays of public spaces. To explore their potential, researchers have recently started to develop(More)
In this paper we investigate interaction with a media fa&#231;ade that is out of reach for touch-based interaction. We describe four different applications that utilize mobile devices to enable passers-by to interact with the fa&#231;ade. Each application has been designed constrained by limitations given by formal regulations of an editorial board (e.g. to(More)
