Busy flag just got better: Application of lighting effects in mediating social interruptions

In this paper we present a system for mediating social interruptions in home or office environment, based on the use of a novel technique of light-based busy flags. The system uses a scalable set of sensors to estimate user availability and to announce this information to possible interrupters (e.g. workplace colleagues) by using dynamic, programmable DMX lighting effects. Our motivation is based on the repeated findings that traditional busy flags do not keep people from interrupting each other when the interruption is least desired. We argue that the use of lighting effects may significantly decrease the number of social interruptions and reduce risk factors influencing performance attainment, such as fatigue, anxiety and stress. In support to our claims we provide the results of an experiment conducted in an office environment.
