Making Sense of Sensemaking 1: Alternative Perspectives

Abstract: Sensemaking has become an umbrella term for efforts at building intelligent systems. This essay examines sensemaking from various perspectives to see if we can separate the things that are doable from the things that seem more like pie-in-the-sky

Designing for Situation Awareness: An Approach to User-Centered Design, Second Edition

Abstract: The barrage of data overload is threatening the ability of people to effectively operate in a wide range of systems including aircraft cockpits & ground control stations, military command and control centers, intelligence operations, emergency management, medical systems, air traffic control centers, automobiles, financial and business management systems, space exploration, and power and process control rooms All of these systems need user interfaces that allow people to effectively manage the information available to gain a high level of understanding of what is currently happening and projections on what will happen next They need systems designed to support Situation Awareness Addressing the information gap between the plethora of disorganized, low-level data and what decision makers really need to know, Designing for Situation Awareness: An Approach to User-Centered Design, Second Edition provides a successful, systematic methodology and 50 design principles for engineers and designers seeking to improve the situation awareness of their systems users based on leading research on a wide range of relevant issues So, whats new in the Second Edition: Significantly expanded and updated examples throughout to a wider range of domains New Chapters: Situation Awareness Oriented Training and Supporting SA in Unmanned and Remotely Operated Vehicles Updated research findings and expanded discussion of the SA design principles and guidelines to cover new areas of development Mica R Endsley is a pioneer and world leader in the study and application of situation awareness in advanced systems Debra G Jones work is focused on designing large-scale and complex systems to support situation awareness and dynamic decision making Completely revised and updated, liberally illustrated with actual design examples, this second edition demonstrates how people acquire and interpret information and examines the factors that undermine this process Endsley and Jones distill their expertise and translate current research into usable, applicable methods and guidelines

Processing Social Media Messages in Mass Emergency: A Survey

Abstract: Social media platforms provide active communication channels during mass convergence and emergency events such as disasters caused by natural hazards. As a result, first responders, decision makers, and the public can use this information to gain insight into the situation as it unfolds. In particular, many social media messages communicated during emergencies convey timely, actionable information. Processing social media messages to obtain such information, however, involves solving multiple challenges including: parsing brief and informal messages, handling information overload, and prioritizing different types of information found in messages. These challenges can be mapped to classical information processing operations such as filtering, classifying, ranking, aggregating, extracting, and summarizing. We survey the state of the art regarding computational methods to process social media messages and highlight both their contributions and shortcomings. In addition, we examine their particularities, and methodically examine a series of key subproblems ranging from the detection of events to the creation of actionable and useful summaries. Research thus far has, to a large extent, produced methods to extract situational awareness information from social media. In this survey, we cover these various approaches, and highlight their benefits and shortcomings. We conclude with research challenges that go beyond situational awareness, and begin to look at supporting decision making and coordinating emergency-response actions.

The effects of level of automation and adaptive automation on human performance, situation awareness and workload in a dynamic control task

Abstract: This paper extends previous research on two approaches to human-centred automation: (1) intermediate levels of automation (LOAs) for maintaining operator involvement in complex systems control and facilitating situation awareness; and (2) adaptive automation (AA) for managing operator workload through dynamic control allocations between the human and machine over time. Some empirical research has been conducted to examine LOA and AA independently, with the objective of detailing a theory of human-centred automation. Unfortunately, no previous work has studied the interaction of these two approaches, nor has any research attempted to systematically determine which LOAs should be used in adaptive systems and how certain types of dynamic function allocations should be scheduled over time. The present research briefly reviews the theory of human-centred automation and LOA and AA approaches. Building on this background, an initial study was presented that attempts to address the conjuncture of these two approa...
