Multi-touch technology and digital tabletops have been used in different fields. They provide a natural way of interaction with computers through gestures. In this report, we present a digital desk for power plant control rooms aimed at visualizing the power grid status. The thesis reports about the development of this desk that comprised field studies, use cases and requirements identification, low fidelity prototyping, and software development. A final evaluation of the design indicated that digital tabletops can be valuable for control room operators since they can enhance learning and communication among the collaborating operators. The work was done at ABB Corporate Research in Sweden.
