UniPad is a face-to-face, digital simulation for use in classroom settings that runs on shared tablets and a wall display. The goal is to encourage students to talk, collaborate and make decisions together in real-time, by switching between working on shared 'small group' devices and a 'whole classroom' public display - instead of working by themselves(More)
Multi-touch tabletops have been much heralded as an innovative technology that can facilitate new ways of group working. However, there is little evidence of these materialising outside of research lab settings. We present the findings of a 5-week in-the-wild study examining how a shared planning application - designed to run on a walk-up-and-use tabletop -(More)
There are a number of mobile shopping aids and recommender systems available, but none can be easily used for a weekly shop at a local supermarket. We present a minimal, mobile and fully functional lambent display that clips onto any shopping trolley handle, intended to nudge people when choosing what to buy. It provides salient information about the food(More)
There is much potential for supporting collaborative learning with interactive computer simulations in formal education and professional training. A number have been developed for single user and remote interaction. In contrast, our research is concerned with how such learning activities can be designed to fit into co-located large group settings, such as(More)
The iPad is typically perceived as a personal device, evoking the image of its owner tapping away - silently submerged in their private digital bubble. Here we portray iPads in a different light: Face-to-face play in groups, using connected and shared surfaces. Applying the bubble metaphor to multi-user cases, we ask the following questions: (a) How many(More)
