Image of two new user interface paradigms for transitions in co-located collaborative work. To the left, Slam-to-Share enables sharing across mobile devices by slamming a meeting table. To the right, KirigamiTable transforms its surface shape in transitions between individual and collaborative work. In his PhD project, Jens Emil contributed to a deeper understanding of how technologies can support changing configurations of people and activities. The combination of empirical, conceptual and experimental work has both inspired future research and led to new insights on how these technologies may change current practices.

Three people meet to work on a slide deck together. They all place their mobile devices on a table, and one of them slams the table surface with the fist. The devices jointly sense the impact and connect to each other. Now, the three users are ready to collaborate on the slides across their devices. This is just one of several prototype concepts that Jens Emil developed during his PhD.

Engaging in co-located collaboration, people often transition between individual and shared work, organizing themselves flexibly around computing devices and furniture. However, current technologies lack support for such transitions. Addressing this issue, Jens Emil’s research shows how interactive technologies can be designed to support more flexibility – both in how we share digital content and how we transition between different ways of working together in physical spaces. The research contributions build on proxemics – the study of how humans interact with each other in shared physical space.

Jens Emil experimented with two new “paradigms”: (1) cross-device interaction, enabling flexible connectivity as well as spatial distribution of digital content and control; and (2) shape-changing tabletops, enabling transitions in users’ physical organization and collaboration around shared digital content. Jens Emil’s research contributes to the understanding of how novel interactive technologies can be designed to support more flexibility in co-located digital sharing and physical organization of collaborative activities.

 This PhD project was conducted in the Ubiquitous Computing and Interaction Group, Department of Computer Science, Science and Technology, Aarhus University, with support from Microsoft Research, Cambridge, UK.
