Advanced manned space flight simulation and training: An investigation of simulation host computer system concepts

The findings of a preliminary investigation by Southwest Research Institute (SwRI) in simulation host computer concepts is presented. It is designed to aid NASA in evaluating simulation technologies for use in spaceflight training. The focus of the investigation is on the next generation of space simulation systems that will be utilized in training personnel for Space Station Freedom operations. SwRI concludes that NASA should pursue a distributed simulation host computer system architecture for the Space Station Training Facility (SSTF) rather than a centralized mainframe based arrangement. A distributed system offers many advantages and is seen by SwRI as the only architecture that will allow NASA to achieve established functional goals and operational objectives over the life of the Space Station Freedom program. Several distributed, parallel computing systems are available today that offer real-time capabilities for time critical, man-in-the-loop simulation. These systems are flexible in terms of connectivity and configurability, and are easily scaled to meet increasing demands for more computing power

Object Manipulation in Virtual Reality Under Increasing Levels of Translational Gain

Room-scale Virtual Reality (VR) has become an affordable consumer reality, with applications ranging from entertainment to productivity. However, the limited physical space available for room-scale VR in the typical home or office environment poses a significant problem. To solve this, physical spaces can be extended by amplifying the mapping of physical to virtual movement (translational gain). Although amplified movement has been used since the earliest days of VR, little is known about how it influences reach-based interactions with virtual objects, now a standard feature of consumer VR. Consequently, this paper explores the picking and placing of virtual objects in VR for the first time, with translational gains of between 1x (a one-to-one mapping of a 3.5m*3.5m virtual space to the same sized physical space) and 3x (10.5m*10.5m virtual mapped to 3.5m*3.5m physical). Results show that reaching accuracy is maintained for up to 2x gain, however going beyond this diminishes accuracy and increases simulator sickness and perceived workload. We suggest gain levels of 1.5x to 1.75x can be utilized without compromising the usability of a VR task, significantly expanding the bounds of interactive room-scale VR

Barriers In Digital Workplaces During Covid-19 Lockdowns: A Phenomenological Longitudinal Study Using Actor-Network Theory

We present a one-year longitudinal phenomenological study that explores how individuals perceived and overcame barriers to remote work during Covid-19 lockdowns. Our study builds upon a previous systematic literature review and utilizes actor-network theory (ANT) to analyze data collected from a survey and two rounds of interviews spaced one year apart. Through this approach, we gain insights into the networks of human and non- human actors that emerged and the challenges faced by remote employees. We compiled a comprehensive list of barriers to anticipate in these circumstances and identified those unique to extreme situations. These findings have implications for companies seeking to establish digital workplaces resilient to future crises

A Pedagogy for Original Synners

Part of the Volume on Digital Young, Innovation, and the UnexpectedThis essay begins by speculating about the learning environment of the class of 2020. It takes place entirely in a virtual world, populated by simulated avatars, managed through the pedagogy of gaming. Based on this projected version of a future-now-in-formation, the authors consider the implications of the current paradigm shift that is happening at the edges of institutions of higher education. From the development of programs in multimedia literacy to the focus on the creation of hybrid learning spaces (that combine the use of virtual worlds, social networking applications, and classroom activities), the scene of learning as well as the subjects of education are changing. The figure of the Original Synner is a projection of the student-of-the-future whose foundational literacy is grounded in their ability to synthesize information from multiple information streams

Emerging digital media, games and simulations: a challenge for open and distance learning

In this article we examine the state-of-the-art research related to digital media in education and evaluate the information concerning a new generation of students that are communityminded and technologically savvy, highlighting the innovative technology behind the new interaction and communication processes, and assessing the challenges for Open and Distance Learning (ODL). Where traditional distance education is based on the completion of carefully graded assignments and tests, today games, simulations and virtual environments may become safe platforms for trial and error experimentation. With games the chance of failure is high, but the cost is low and the lessons are learned immediately and with greater emotional impact. However, these conditions may become more difficult to address when the volume of users increases from small to medium, large or extra-large. Dealing effectively with tens or even hundreds of thousands of students in absentia requires following very sound organizational principles and good technical implementation, systematic monitoring of deviations from established norms, regular audition of users' comments and criticisms, careful analysis of final results. In this emerging scenario, involving digital media, games and simulations, ODL systems must have means of establishing rich connections with each member of the universe of users. In this sense we propose using a virtual space with multiple places, in ways that use the Internet, social applications, games and mobile devices to involve students in pedagogical activities
