Using virtual models of a real environment to improve performance and design effective and efficient user interfaces has always been a matter of choice to provide control of complex environments. The concept of Dual Reality has gone one step further in synchronizing a real environment with its virtualiza- tion. So far, little is known about the design of effective Dual-Reality interfaces. With this paper we want to shed light on this topic by comparing the strategies, performances and efficiency in a real, virtualized and a DR setting given a com- plex task. We propose a cost and efficiency measure for complex tasks, and have conducted an experiment over a complex shelf planning task. Our results show that for certain tasks interacting with the virtual world yields to better results, whereas the best effectivity can be observed in a Dual-Reality setup. We discuss these results and present design guidelines for future Dual Reality interfaces.
