Designing Multi-user Lighting Interfaces: Four strategies to implement Social Translucence

In this work, we investigate how to design multi-user interfaces for shared environments by implementing social translucence: Visibility of socially relevant information, awareness of other people, and accountability for actions. By designing and analysing 126 multi-user lighting interface concepts, we define four strategies to implement socially relevant information into a user interface. The strategies are: (1) to direct attention towards the context, (2) to present information about previous interactions, (3) to make information about needs and wishes explicit, and (4) to facilitate pre-evaluation of a light setting and its impact.
