Impacts of Multimodal Displays with Small Mobile Viewscapes on Operators in Safety-Critical Systems

Real-time information is essential for effective operator decision making and performance in safety-critical systems, as operators must make crucial decisions quickly, utilizing relevant information to monitor, assess and respond. Research examining the impact of ultimodal displays with augmented reality (AR) on operators performing safety-critical work has shown improved operator situation awareness, but mixed results with respect to performance and workload. Multiple-resource theory (MRT) posits that individuals will experience different performance impacts when information is received using different modalities, compared to when the information is communicated using a single modality. Earlier work provides a theoretical basis for expectations about the impacts of multimodal displays, but does not address the costs or impacts of digital layers of AR imagery in multimodal displays with small viewscapes, a gap our research addresses in safety-critical systems such as Arctic search and rescue and maritime navigation

Evaluation techniques used to evaluate extended reality (XR) head mounted displays (HMDs) used in healthcare: A literature review

Extended Reality (XR) Head Mounted Displays (HMDs) are used across various healthcare pathways for staff/student education and training, and for improving patient experiences. As XR HMDs become affordable, accessible and their acceptance increases, it is critical to document the techniques used for evaluating the technology, processes of user engagement and immersion, and outcomes. At present there is limited research on evaluation techniques used to evaluate XR HMDs. This manuscript presents findings from 104 clinical studies that use XR HMDs. The aim of this review is to give the user an insight into the current healthcare XR HMD landscape by presenting the different HMDs used, variety of XR interventions and their applications across medical pathways and intended research outcomes of the XR applications. The manuscript further guides the reader toward a detailed documentation of evaluation techniques used to investigate antecedents and consequences of using XR and delivers a critical discussion and suggestions for improvement of XR evaluation practices. This paper will be of excellent use to clinicians, academics, funding bodies and hospital decision makers who would like suggestions for evaluating the efficacy and effectiveness of XR HMDs. The authors hope to encourage discussions on the importance of improving XR evaluation practices

Integrating Haptic Feedback into Mobile Location Based Services

Haptics is a feedback technology that takes advantage of the human sense of touch by applying forces, vibrations, and/or motions to a haptic-enabled device such as a mobile phone. Historically, human-computer interaction has been visual - text and images on the screen. Haptic feedback can be an important additional method especially in Mobile Location Based Services such as knowledge discovery, pedestrian navigation and notification systems. A knowledge discovery system called the Haptic GeoWand is a low interaction system that allows users to query geo-tagged data around them by using a point-and-scan technique with their mobile device. Haptic Pedestrian is a navigation system for walkers. Four prototypes have been developed classified according to the user’s guidance requirements, the user type (based on spatial skills), and overall system complexity. Haptic Transit is a notification system that provides spatial information to the users of public transport. In all these systems, haptic feedback is used to convey information about location, orientation, density and distance by use of the vibration alarm with varying frequencies and patterns to help understand the physical environment. Trials elicited positive responses from the users who see benefit in being provided with a “heads up” approach to mobile navigation. Results from a memory recall test show that the users of haptic feedback for navigation had better memory recall of the region traversed than the users of landmark images. Haptics integrated into a multi-modal navigation system provides more usable, less distracting but more effective interaction than conventional systems. Enhancements to the current work could include integration of contextual information, detailed large-scale user trials and the exploration of using haptics within confined indoor spaces

Trends and features of virtual reality: a literature review between 2017 and 2018

Virtual Reality has greatly evolved since the 1960´s to the present. It has been implemented in multiple research and knowledge areas, the most recognized being the entertainment industry. In order to establish the state of Virtual Reality and get an idea of its prospects, 537 scientific documents have been reviewed, applying search criteria, more specifically, Virtual Reality applied to education. A bibliometric analysis was realized based on summarizing each document, as well as its keywords and trends, then proceeding to categorize each one, according to the field of application. It was found that Virtual Reality is having relevance in medicine and training area, due to the ability to simulate difficult situations and above all, specific conditions raised by instructors. The future of Virtual Reality as a tool to train professionals in multiples areas is promising.La realidad virtual ha tenido una gran evolución desde la década de 1960 hasta el día de hoy. Se ha implementado en múltiples áreas, tanto de la investigación como del conocimiento, siendo más reconocida en la industria del entretenimiento. Con el propósito de establecer el estado de la realidad virtual y obtener una idea de su futuro, 537 documentos científicos han sido revisados aplicando criterios de búsqueda específicos, como realidad virtual aplicada a la educación. Un análisis bibliométrico fue realizado, teniendo como base un resumen y descripción de cada artículo, así como sus palabras claves y tendencias, procediendo a categorizar cada documento de acuerdo con su campo de aplicación. Se encontró que la realidad virtual tiene una gran relevancia en la medicina, industria militar y en el entrenamiento de personas, debido a su capacidad de simular situaciones difíciles y, sobre todo, condiciones específicas requeridas por instructores. El futuro de la realidad virtual como herramienta de entrenamiento para los profesionales de múltiples áreas es promisori

Young Female College Millennials\u27 Intent for Behavior Change with Wearable Fitness Technology

Among young college-aged females, overweight and obesity, type 2 diabetes, uncontrolled hypertension, and high stress levels have increased, causing overall worse health conditions than previous generations. The use of wearable fitness technology (WFT) by young adults assists in fitness and nutrition monitoring, provides feedback in health statistics, and has shown improvements in reducing health-related issues in young college females. A wide body of literature related to physical activity, nutrition, and health issues in young college females exists; however, the experiences and intent of WFT use for behavior change by young college female millennials has not been well researched. The purpose of this phenomenological study was to examine the lived experiences of young college females\u27 intent for behavior change with WFT. The health belief model was the theoretical framework used for this study. Ten college females, 18-25 years of age, attending colleges in northern West Virginia, who were collecting data from a WFT for a minimum of six months completed individual face-to-face interviews. Data were analyzed using phenomenological thematic analysis. Results from the study revealed young college females use WFT to increase physical activity, identify calorie intake and energy expenditure, and monitor heart rate, sleep, and stress to decrease and prevent health issues. These results can provide evidence for other researchers to address the current health inequalities in young college adults. Positive social change implications could include the value of WFT regarding the growing evidence of the importance of physical activity and nutrition by young female college students related to positive health outcomes and reducing health issues in this specific population
