On average, humans blink between eight and 21 times per minute while resting. Eye actions are influenced by external and internal stimuli. This can be utilized to measure internal cognition specifically focus and attention while performing tasks. In this experiment, an individual’s self-perceived focus, attention and interaction level is collected and then correlated with eye blinks rate. The subjects are observed while performing experiments using haptic devices in a virtual environment. The experiment was modulated based on network quality and hardware quality to further quantify the effect of each scenario on subjects’ intrinsic and extrinsic focus indicators. The experiment quantified the blinks and formulated a correlation between subjects’ own perception of the event using statistical analysis. It can be found that there is an acceptable correlation between certain indicators, network quality, fatigue, stress, focus and enjoyability of the experiments. A good quality hardware and network did enhance the experience in all the subjects indicating a need for enhanced services for haptic and immersed mixed reality activities directly affecting the cognition especially in education tools. It can be inferred that eye blink rate can be used as an additional tool for measuring the cognition of individuals experience using haptic and virtual reality tools.

Abstract. Background: Lowered eye blink rate may be a clinically useful indicator of acute, imminent, and severe suicide risk. Diminished eye blink rates are often seen among individuals engaged in heightened concentration on a specific task that requires careful planning and attention. Indeed, overcoming one’s biological instinct for survival through suicide necessitates premeditation and concentration; thus, a diminished eye blink rate may signal imminent suicidality. Aims: This article aims to spur research and clinical inquiry into the role of eye blinks as an indicator of acute suicide risk. Method: Literature relevant to the potential connection between eye blink rate and suicidality was reviewed and synthesized. Results: Anecdotal, cognitive, neurological, and conceptual support for the relationship between decreased blink rate and suicide risk is outlined. Conclusion: Given that eye blinks are a highly observable behavior, the potential clinical utility of using eye blink rate as a marker of suicide risk is immense. Research is warranted to explore the association between eye blink rate and acute suicide risk.

This paper looks to expand on the INEC 2016 paper ‘The future role of virtual reality within warship support solutions for the Queen Elizabeth Class aircraft carriers’ presented by Ross Basketter, Craig Birchmore and Abbi Fisher from BAE Systems in May 2016 and the EAAW VII paper ‘Testing the boundaries of virtual reality within ship support’ presented by John Newell from BAE Systems and Simon Luck from BMT DSL in June 2017. BAE Systems and BMT have developed a 3D walkthrough training system that supports the teams working closely with the QEC Aircraft Carriers in Portsmouth and this work was presented at EAAW VII. Since then this work has been extended to demonstrate the art of the possible on Type 26. This latter piece of work is designed to explore the role of 3D immersive environments in the development and fielding of support and training solutions, across the range of support disciplines. The combined team are looking at how this digital thread leads from design of platforms, both surface and subsurface, through build into in-service support and training. This rich data and ways in which it could be used in the whole lifecycle of the ship, from design and development (used for spatial acceptance, HazID, etc) all the way through to operational support and maintenance (in conjunction with big data coming off from the ship coupled with digital tech docs for maintenance procedures) using constantly developing technologies such as 3D, Virtual Reality, Augmented Reality and Mixed Reality, will be proposed.  The drive towards gamification in the training environment to keep younger recruits interested and shortening course lengths will be explored. The paper develops the options and looks to how this technology can be used and where the value proposition lies.

Virtual reality (VR) is the term used to describe representation and perception in a computer-generated, virtual environment. The term was coined by author Damien Broderick in his 1982 novel “The Judas Mandala". The term "Mixed Reality" describes the mixing of virtual reality with pure reality. The term "hyper-reality" is also used. Immersion plays a major role here. Immersion describes the embedding of the user in the virtual world. A virtual world is considered plausible if the interaction is logical in itself. This interactivity creates the illusion that what seems to be happening is actually happening. A common problem with VR is "motion sickness." To create a sense of immersion, special output devices are needed to display virtual worlds. Here, "head-mounted displays", CAVE and shutter glasses are mainly used. Input devices are needed for interaction: 3D mouse, data glove, flystick as well as the omnidirectional treadmill, with which walking in virtual space is controlled by real walking movements, play a role here.

Recent advances in technology have made virtual environments, virtual reality, augmented reality, and simulations more affordable and accessible to researchers, companies, and the general public, which has led to many novel use cases and applications. A key objective of human factors research and practice is determining how these technology-rich applications can be designed and applied to improve human performance across a variety of contexts. This session will demonstrate some of the distinct and diverse uses of virtual environments and mixed reality environments in an alternative format. The session will begin with each demonstrator providing a brief overview of their virtual environment (VE) and a description of how it has been used to address a particular problem or research need. Following the description portion of the session, each VE will be set-up at a demonstration station in the room, and session attendees will be encouraged to directly interact with the virtual environment and ask demonstrators questions about their research and inquire about the effectiveness of using VE for research, training, and evaluation purposes. The overall objective of this alternative session is to increase the awareness of how human factors professionals use VE technologies and increase the awareness of the capabilities and limitations of VE in supporting the work of HF professionals.

Current teaching practice in undergraduate higher education anatomy and physiology courses incorporates the use of various instructional methodologies to reinforce the anatomical relationships between structures.1,2 These methods can include basic hands-on physical models, human and animal dissection labs, and interactive technology. Technological advances continue to drive the production of innovative anatomy and physiology electronic tools, including:virtual dissection in 3-D (e.g., Virtual Dissection Boards from Anatomage, 3D4Medical, and Anatomy.TV),augmented reality (AR) (e.g., Human Anatomy Atlas),mixed reality (e.g., Microsoft HoloLens Case Western Reserve Medical School and Cleveland Clinic digital anatomy app), and3-D virtual reality (VR) (e.g., 3D Organon VR Anatomy and YOU by Sharecare apps).

Even experienced mountain climbers underestimate key dangers and make poor decisions in stressful, high-risk situations when climbing, leading to injury and death. My own experience indicates that effective education can play a key role in managing these risks and improving experienced climber’s decision making. Current educational approaches for climbers, however, are generally limited to textbooks and ‘on the mountain’ learning. It is vital, therefore, that new approaches and methods are developed to improve learning.    My own experience and emergent case studies indicate that AR (Augmented), VR (Virtual Reality) and MR (Mixed Reality), have affordances (possibilities offered by the technology) to underpin new forms of learning and therefore have the potential to enhance education for high-risk environments. Emergent use of MR immersive technologies includes classroom learning, firefighting and military training. An initial review of literature has indicated though that there are very limited examples of rigorous research on the design and application of MR technologies in authentic education, especially for extreme situations such as mountaineering i.e., no one has rigorously designed for these technologies for learning in extreme environments, evaluated learning outcomes and theorised about how learning can be enhanced.    In response to this gap/opportunity, this research explores the potential of MR technologies to effectively enhance learning for authentic, high-risk situations. The research will use a Design-based research methodology (DBR) to develop design principles informed by key learning theories as they offer recognised and critical approaches for a new way of learning in an extreme environment.  Underpinned by a Constructivist paradigm, initial theoretical frameworks identified include Authentic Learning and Heutagogy (student-determined learning).Herrington and co-authors (2009) recommended 11 design principles for the incorporation of mobile learning into a higher education learning environment, and Blaschke and Hase (2015)’s 10 principles of designing learning for heutagogy. Other theories and frameworks include Constructivist Learning and the ZPD (the Zone of Proximal Development), design for mobile MR learning and user-centred design. Activity Theory will also be utilised in the data analysis.   Initial design principles will be developed by the DBR methodology. These design principles will be tested through the implementation and evaluation of an MR ‘prototype’ app design solution.’ The prototype solution will be iteratively redesigned using further evaluation and feedback from sample cohorts of end-users. Data will be collected from key participant interviews, researcher observation/reflections and biometric feedback. Methodological triangulation (multimodal data approach) will be used to evaluate learning outcomes. The iterative development will lead to transferable design principles and further theorising that can be transferred to other learning situations involving preparation and decision-making as well as knowledge in high-risk contexts.    Reference   Amiel, T., & Reeves, T.
