User interfaces and visualisations are part of group problem solving. Technology is already a part of daily decision-making in multidisplay environments, both as communication tools and information devices. As these devices, such as large displays and visualisation tools become more accessible, there is an increasing opportunity to develop applications that enhance group decision-making abilities, rather than restrict them. This chapter presents the results of the empirical user study on the effect of the Highlighting-on-Demand concept on situational awareness and satisfaction with the group decision-making process in a real multidisplay environment. Highlighting-on-Demand interface enables a team member who is currently controlling the shared large display to draw attention of the other team members by highlighting certain visualisation. Displaying all alternatives on a shared large display fosters information sharing and the Highlighting-on-Demand interface enables group members to draw attention to certain visualisation, while keeping the other alternatives still in view.The results suggest that when group members use the Highlighting-on-Demand interface during the discussion, the satisfaction with the final group decision increases. Participants expressed willingness to use the Highlighting awareness support for visualising real data (e.g., biomedical, omics experiments) and manipulating how the data is visualised to discuss the experiment results with other team members in real project discussions.
