One of the first projects where multi-touch tabletops were seen as a way to support command and control in the military and naval domain was the ROLF 2010 project [73], which dates back to 1998. The purpose of ROLF 2010 was to investigate a vision about future (10-15 years) command and control on the operational level for the Swedish Armed Forces. In their vision, success would be dependent on the ability to understand and control situations by dominating the information environment and to be ahead of the actual situation. The commander and other personnel would gather around a shared map as can be seen in figure 2.3. We can see how different users on the map are indicated by the use of different colors.

Kobayashi et al. [74] presented a disaster simulation system that supports collaborative planning of disaster measures. In their implementation they make use of tangibles in the form of “pucks”. The interface supports the creation of scenarios by editing a map where the user can add icons for fire-breaking points, restricted areas and additional population. By rotating the puck on these icons the user can change parameters. The map further

shows water-levels and emergency shelters. Based on the user input evacuation routes are calculated.

In Domova et al. [19] a prototype is presented where a multi-touch tabletop, mobile phones, and PCs are combined to enable crew members of ships to effectively communi- cate and collaborate with their colleagues. The system supports the navigation officers in their management role and provides situational awareness for ongoing processes and a communication tool for direct contact with the workers. The main problem Domova et al. [19] encountered was the responsiveness of the system because of moderate WiFi signals. They made recommendations for the interface: a 3D environment could provide a more natural interface. The multi-touch tabletop itself should be robust enough to withstand rough weather, user wear-and-tear and different lighting conditions, which can be challenging since most multi-touch tables are infrared-based.

Bortolaso et al. [36] describe the OrMiS (Orchestrating Military Simulations) system. OrMiS is a multi-touch tabletop application that supports collaborative analysis, plan- ning and interaction around digital maps. The application was tested during field ob- servations with military personnel and simulation professionals.

While developing OrMiS they found four major design issues; 1. The significant tension between simplicity and functionality. 2. The presentation of visual feedback at the user’s point of touch. 3. That collaboration is more than co-locating people around a table 4. And that the design of the type of application is sensitive to the requirements of the domain.

Based on these issues they made multiple recommendations. For the tension between simplicity and functionality issue, they mentioned that continuous testing with domain experts was required to determine whether their designs were too simple. Their system became dramatically simplified in comparison with the existing PC-based tools, but nonetheless proved capable of supporting realistic simulation-based training scenarios.

The visual feedback issue was tackled by removing the need of secondary controls and placing all relevant information at the point of the users touch. They e.g. used a “line of sight” tool that showed the line of sight of an asset when touched or dragged. They warn for interfaces becoming more complicated than simple touch interaction can sup- port, leading to mode confusion and information overload on the screen.

The collaboration issue was handled by combining overview+detail and focus+context techniques. They used experimental design to identify techniques to allow multiple peo- ple to simultaneously manipulate the map and to support switching between group and personal work. This led to the implementation of personal lenses where the users can zoom in and manipulate the map independently from each other. They also implemented a radar view on a external horizontal lcd-screen, where all users can see in which regions in the map the other users are working.

The requirements issue was encountered by an iterative design process involving deep observation of domain experts and frequent usability testing using realistic scenarios. Finally, they asked themselves how easy it is to share such a system design amongst tabletop applications in other domains. Due to the lack of real tabletop applications answering this question is difficult.

Riley et al. [75] investigated collaborative planning in Army command and control. They observe that management of crisis situations relies upon a C2 structure, with a central commander coordinating the activities of the other agencies or personnel responding to the emergency. It is the commander’s role and his or her support staff to gather and analyze data to develop a response plan, make decisions, and monitor the implementation and consequences of the selected course of action, modifying the plan as needed in response to unanticipated events. They suggest that in the future, systems are desired that incorporate the use of intelligent agents and computational models to support plan development, rehearsal, selection, and execution.

Szymanski et al. [38] describe the COMET multi-touch platform, a command and con- trol application that supports collaborative planning by drawing basic graphs on digital maps, displaying assets and displaying UAV video-streams. By analyzing users they found three types of group collaboration;group search, where mission planning, wargam- ing, common operating picture assessing and intel analysis take place. Discussion pre- sentation, where ideas can be discussed and created on the tabletop, andbriefing, where

one person explains something to a group. They mentioned that by using the tabletop horizontally, the group search style was carried out best.
