Re-Orienting Costs
(D. Tuzar & D. Woods)
This study shows how to use re-orienting cost as a measure of the quality of human-computer interaction for multi-task situations. The study includes designs to reduce re-orienting cost for car in-cab interfaces

Model of Perspective-Taking and the Perspective Controller design
(A. Roesler, now at University of Washington)
A model of perspective-taking as multiple sensors and mobile robotic platforms provide remote observers with new ways to connect to distant situations. The model provides principles for coordination of multiple views from sensors/platforms monitoring remote locations. The model is illustrated by a 3-dimensional view control interface design.

Coordinating Shared Perspectives
(M. Voshell & A. H. J. Oomes)
A new interface concept was developed and implemented to coordinate perspectives between multiple parties using a remote robotic system. A prototype was tested in a robotic search and rescue competition, and won. The system, built using a new framework for rapidly leveraging new navigation interfaces and remote sensor channels, allows us to take concepts quickly from simulation and implement on our robotic platform.

Metric for Evaluating HRI Performance
(M. Voshel & F. Phillips)
Path analysis using fractal geometry provides a new metric for evaluating robot or human-robot team exploration. Simple measurements such as path length and completion times are particularly unsuitable for evaluating human-robot navigation performance in a complex environment with multiple tasks and competing goals. This class of space and time invariant metrics allow us to better analyze human robot exploration, interpret valuable behavioral information for analysis of movement efficiency, path tortuosity, and overall space utilization in relation to handler goals and overall environment characteristics. Not only is this metric valuable for post hoc analysis, but it also serves as a powerful cue to observability when integrated into robot operator displays.

Human-Smart Camera Interaction in Visual Surveillance
(A. Morison, J. Davis)
This work is a new approach to human-camera interaction in visual surveillance by automatically learning scene awareness for a PTZ camera using low level event information (i.e. pedestrian motion). The learned scene awareness provides the camera a goal for moving or scanning around a scene (i.e. scan path) while human-camera coordination is accomplished through a single visualization which provides past, present, and future camera scan path information.

The Effects of Real-time Imaging Technology on Data Gathering and Analysis in Emergency Management (J. McGuirl)
A simulation-based study of Emergency Management personnel and Incident Commanders using a UAV video feed to assist in managing the response to an accident at a petro-chemical facility. FIndings address how commander decision-making and control strategies were affected by direct visual access to the operations area.

Layered CheckZone
(W. Elm, J. Tittle, D. Tinapple, D. Woods)
The Layered CheckZone concept applies CSE design principles to the problem of integrating multiple sensors and intelligent systems with a team of soldiers performing a common but important MOUT function: checkpoint operation. The Layered CheckZone provides a platform for understanding the challenges and exploring potential CSE solutions that arise when multi-sensor, multi-agent systems are teamed with soldiers conducting MOUT.

Study of MI Analysis Processes
(S. Trent, J. Grossman, E. Patterson, M. Voshell et al.)
A two-week study of military intelligence analysis in a counter-insurgency training exercise at the Army intel schoolhouse. Both an exercise in analysis as well as a study of analysis. Findings address information synthesis, cross-checks, connecting analysis to recommendations and inferring intent.

Design Seeds for Information Analysis
(E. Patterson et al.)
Using findings from studies of analysis, collaborative envisioning mechanisms were used to identify promising directions and design seeds to support information analysis and comprehension. Combining many perspectives from around industry and academia, groups brought new insighst to tackle the challenges of modern intelligence. Design seeds looked at technology forecasting and information dynamics, workflows for analyst perspective representation, and the implications of mathematical descriptions of collaborative metadata.

What is the Opposite of Creeping Featurism?
(D. S. Lee, D. Woods, D. Kidwell, H. Tran)
Creeping featurism is a process that produces complexity cumulatively and inadvertently as each individual module seems appropriate when considered on its own. The analysis of different answers to the question of what is the opposite of creeping featurism leads to a new strategy based on tracking fitness in an innovation landscape.

Scenarios As A Tool For Collaborative Envisioning
(J. Schoenwald, J. Tittle, M. Voshell & D. Woods)
The animock serves as a collaborative envisioning tool resulting in new possibilities for sensor technology in MOUT (see url: http://csel.eng.ohio-state.edu/productions/xcta). Combining the Topic Landscape and a simulation engine under the animock design provides narrative to envision and describe inherent complexities in general work, as well as new insight into specific difficulties faced in MOUT.

Assessing Resilience and Safety of Offshore Helicopter Transportation
(T. da Mata, et al., Jose O. Gomes et al., and D. D. Woods
A resilience analysis of offshore helicopter transport operations for a large petrochemical company in Brazil. The analysis identifies gaps created by goal conflicts, tradeoffs, and weak plans/procedures. The gaps are points of brittleness that can contribute to potential future incidents and accidents.
