Emergency Response Planning and Training through Interactive Simulation and Visualization with Decision Support

Abstract: Teams of first responders work together to effectively manage a community-wide crisis. Traditionally, key groups such as police, fire, and medical are each trained for specific emergency procedures. Emergency response teams design training exercises to augment an individual's cognition associated with performing time critical roles. The aggregation of all individual cognition, distributed through communications, suggests a situation awareness that an incident commander requires to perform optimal decision-making. We are developing a computer-supported simulation environment with a decision support tool called the RimSim, to facilitate emergency response planning and training of first responders. We modularize RimSim for synchronous multi-player use or asynchronous individual use with simulated participants. Through interactive computer- supported role-play with shared visualizations, we are able to study distributed cognition with a long-term goal of identifying opportunities for improving information management during emergency response. We aim to improve mindful distributed cognition for first responders during emergency response to natural and man-made crises.

Automation-Level Transference Effects in Simulated Multiple Unmanned Aerial Vehicle Control:

Abstract: Supervisory control of multiple unmanned aerial vehicles (UAVs) raises many questions concerning the balance of system autonomy with human interaction for effective operator situation awareness and system performance. The reported experiment used a UAV simulation environment to evaluate two applications of autonomy levels across two primary control tasks: allocation (assignment of sensor tasks to vehicles) and router (determining vehicles’ flight plans). In one application, the autonomy level was the same across these two tasks. In the other, the autonomy levels differed, one of the two tasks being more automated than the other. Trials also involved completion of other mission-related secondary tasks as participants supervised three UAVs. The results showed that performance on both the primary tasks and many secondary tasks was better when the level of automation was the same across the two sequential primary tasks. These findings suggest that having the level of automation similar across closely coupled ...

The Development of a Telerobotic Rock Breaker

Abstract: This paper describes the development of a tele-robotic rock breaker deployed at a mine over 1000kms from the remote operations centre. This distance introduces a number of technical and cognitive challenges to the design of the system, which have been addressed with the development of shared autonomy in the control system and a mixed reality user interface. A number of trials were conducted, culminating in a production field trial, which demonstrated that the system is safe, productive (sometimes faster) and integrates seamlessly with mine operations.

Human Robot Collaboration: An Augmented Reality Approach—A Literature Review and Analysis

Abstract: Future space exploration will demand the cultivation of human-robotic systems, however, little attention has been paid to the development of human-robot teams. Current methods for autonomous plan creation are often complex and difficult to use. So a system is needed that enables humans and robotic systems to naturally and effectively collaborate. Effective collaboration takes place when the participants are able to communicate in a natural and effective manner. Grounding, the common understanding between conversational participants, shared spatial referencing and situational awareness, are crucial components of communication and collaboration. This paper briefly reviews the fields of human-robot interaction and Augmented Reality (AR), the overlaying of computer graphics onto the real worldview. The strengths of AR are discussed and how they might be used for more effective human-robot collaboration is described. Then a description of an architecture that we have developed is given that uses AR as a means for real time understanding of the shared spatial scene. This architecture enables grounding and enhances situational awareness, thus laying the necessary groundwork for natural and effective human-robot collaboration.Copyright © 2007 by ASME

Comparison between Simulation-based Training and Lecture-based Education in Teaching Situation Awareness. A Randomized Controlled Study

Abstract: Rationale: Situation awareness has been defined as the perception of the elements in the environment within volumes of time and space, the comprehension of their meaning, and the projection of their status in the near future. Intensivists often make time-sensitive critical decisions, and loss of situation awareness can lead to errors. It has been shown that simulation-based training is superior to lecture-based training for some critical scenarios. Because the methods of training to improve situation awareness have not been well studied in the medical field, we compared the impact of simulation vs. lecture training using the Situation Awareness Global Assessment Technique (SAGAT) score.Objectives: To identify an effective method for teaching situation awareness.Methods: We randomly assigned 17 critical care fellows to simulation vs. lecture training. Training consisted of eight cases on airway management, including topics such as elevated intracranial pressure, difficult airway, arrhythmia, and shock. Dur...
