The main goal of the field of augmented cognition is to research and develop adaptive systems capable of extending the information management capacity of individuals through computing technologies. Augmented cognition research and development is therefore focused on accelerating the production of novel concepts in human-system integration and includes the study of methods for addressing cognitive bottlenecks (e.g., limitations in attention, memory, learning, comprehension, visualization abilities, and decision making) via technologies that assess the user’s cognitive status in real time. A computational interaction employing such novel system concepts monitors the state of the user, through behavioral, psychophysiological, and neurophysiological data acquired from the user in real time, and then adapts or augments the computational interface to significantly improve their performance on the task at hand. The International Conference on Augmented Cognition (AC), an affiliated conference of the HCI International (HCII) conference, arrived at its 16th edition and encouraged papers from academics, researchers, industry, and professionals, on a broad range of theoretical and applied issues related to augmented cognition and its applications. The field of augmented cognition has matured over the years to solve enduring issues such as portable, wearable neurosensing technologies and data fusion strategies in operational environments. These innovations coupled with better understanding of brain and behavior, improved measures of brain state change, and improved artificial intelligence algorithms have helped expand the augmented cognition focus areas to rehabilitation, brain-computer interfaces, and training and education. The burgeoning field of human-machine interfaces such as drones and autonomous agents are also benefitting from augmented cognition research. This volume of the HCII 2022 proceedings is dedicated to this year’s edition of the AC conference and focuses on topics related to understanding human cognition and behavior, brain activity measurement and electroencephalography, human and machine learning, and augmented cognition in extended reality. Papers of this one volume are included for publication after a minimum of two single-blind reviews from the members of the AC Program Board or, in some cases, from members of the Program Boards of other affiliated conferences. We would like to thank all of them for their invaluable contribution, support, and efforts.

While virtual, augmented, and mixed reality technologies are being used for military medical training and beyond, these component technologies are oftentimes utilized in isolation. eXtended Reality (XR) combines these immersive form factors to support a continuum of virtual training capabilities to include full immersion, augmented overlays that provide multimodal cues to personalize instruction, and physical models to support embodiment and practice of psychomotor skills. When combined, XR technologies provide a multi-faceted training paradigm in which the whole is greater than the sum of the constituent capabilities in isolation. When XR applications are adaptive, and thus vary operational stressors, complexity, learner assistance, and fidelity as a function of trainee proficiency, substantial gains in training efficacy are expected. This paper describes a continuum of XR technologies and how they can be coupled with numerous adaptation strategies and supportive artificial intelligence (AI) techniques to realize personalized, competency-based training solutions that accelerate time to proficiency. Application of this training continuum is demonstrated through a Tactical Combat Casualty Care training use case. Such AI-enabled XR training solutions have the potential to support the military in meeting their growing training demands across military domains and applications, and to provide the right training at the right time.

Given the sometimes disparate findings and the increasing application of AR in both training and operations, as well as increased affordability and availability, it is important for researchers, user interface and user experience (UI/UX) designers, and AR technology developers to understand the factors that impact the utility of AR. To increase the potential for realizing the full benefit of AR, adequately detailing the interrelated factors that drive outcomes of different AR usage schemes is imperative. A systematic approach to understanding influential factors, parameters, and the nature of the influence on performance provides the foundation for developing AR usage protocols and design principles, which currently are few. Toward this end, this work presents a theoretical model of factors impacting performance with AR systems. The framework of factors, including task, human, and environmental factors, conceptualizes the concept of “AR Receptivity”, which aims to characterize the degree to which the application of AR usage is receptive to the technology design and capabilities. The discussion begins with a brief overview of research efforts laying the foundation for the model’s development and moves to a review of receptivity as a concept of technology suitability. This work provides details on the model and factor components, concluding with implications for application of AR in both the training and operational settings.

Objective: To examine the feasibility of utilizing electronic health records (EHR) to determine a metric for identifying physician diagnostic and treatment deviations in standards of care for different disease states. Methods: A Boolean-rule-based model compared deviations in standards of care across four disease states: diabetes, cardiovascular disease, asthma, and rheumatoid arthritis. This metric was used to identify the relationship between physician deviations in standards of care procedures, before and after diagnosis, for 76 internal medicine physicians. Results: The Boolean-rule-based model identified patterns of standards of care deviation for the physicians before diagnosis and during treatment. The deviations identified for each of the four disease states were then related to Continuing Medical Education courses that could support further training. The rule-based model was extended and improved by including system and process aspects of medical care that are not specifically related to the physician, yet potentially have an impact on the physician's decision to deviate from the standards of care. Conclusion: The Boolean-rule-based approach provided a means to systematically mine EHRs and use these data to assess deviations in standards of care that could identify quality of care issues stemming from system processes or the need for specific CME for a physician.

... Despite the capability of interpreting self-report data, the subjective methods suffer from recall and selective reporting biases (Stone and Shiffman 1994;Fuge 2015). Recent efforts have been geared towards an objective route (neurophysiology-oriented) by means of monitoring the participant's behavioural indicators or physiological signals (Schmorrow and Fidopiastis 2016). However, relying on one single channel of physiological measure alone can hardly be adequate to give a full picture of what cognitive states occur with the user (Siddhartha and Dagli 2013); and thus it is necessary to monitor diverse physiological signals collectively (Nicholson et al. 2005). ...

... Thus, the value in the testbed approach is in determining viable components of the ITS as part of the initial development cycle. The key is that transferring the simulation-based efficacy to the actual training effectiveness requires sensors and associated algorithms integrated within the real world context (Hou and Fidopiastis 2014). Three main design issues still faced are: (1) defining metrics derived from the multimodal data streams that reliably predict the learner's cognitive state, (2) determining the relationship of the metric and that of mitigation selection and (3) developing metrics to assess the construct validity of the ITS and the learning transfer to the operational environment. ...

Untangling Operator Monitoring Approaches When Designing Intelligent Adaptive Systems for Operational Environments

... When ideas and approaches from AugCog are applied to the modulation of functionality and information flow in infocommunication systems, the links between the field and CogInfoCom are clear. Especially interesting applications are possible when results in AugCog are applied to the sensing of cognitive states in scenarios with multiple participants and multiple devices, as suggested, for example, in (Skinner et al. 2013). Such applications are eventually expected to lead to new kinds of "augmented sensors" that are capable of understanding distributed phenomena based on multimodal activities in ICT networks (possible examples include the filtering of relevant data from vast records of social network activity on e.g. ...
