Demand for a highly skilled workforce in the field of additive manufacturing (AM) is growing but is underserved due to limited academic course offerings and high barriers for incorporating industrial AM systems into education. Virtual reality (VR) is proposed as a medium to help teach introductory concepts of AM to a broader audience in an interactive, scalable manner. Before implementing VR as a standard tool to teach the concepts of AM, we must evaluate the effectiveness of this medium for the subject. Our research aims to answer the question: can VR be used to teach introductory concepts of additive manufacturing in a way that is as effective as teaching the same concepts in a physical setting? The research looks at the learning differences between two groups: (1) students exposed to an interactive AM lesson in a traditional physical setting and (2) students exposed to the same lesson within a virtual environment. The study assesses participants’ AM knowledge through pre-/post-AM lesson evaluation. AM conceptual knowledge gained and changes in self-efficacy are evaluated to make an argument for the effectiveness of VR as an AM learning tool.

Abstract Limited academic course offerings and high barriers to incorporate industrial additive manufacturing (AM) systems into education has led to an underserved demand for a highly skilled AM workforce. In this research, virtual reality (VR) is proposed as a medium to help teach introductory concepts of AM in an interactive, scalable manner. Before implementing VR as a standard tool to teach introductory concepts of AM, we must evaluate the effectiveness of this medium for the subject. We test the hypothesis that VR can be used to teach students introductory concepts of AM in a way that is as effective as teaching the same concepts in a real-world physical setting. The research also explores differences in learning between participants who engage in a hands-on interactive lesson and participants who engage in a hands-off passive lesson. The study assesses participants’ AM knowledge through pre-/post-AM lesson evaluation. AM conceptual knowledge gained and changes in self-efficacy are evaluated to make an argument for the effectiveness of VR as an AM learning tool. Our findings in this research indicate that both interactive and passive VR may be indeed used to effectively teach introductory concepts of AM; we also found advantages to using interactive VR for improving AM self-efficacy.

Processing Mechanisms

The role of top-down processing on the horizontal-vertical line length illusion was examined by means of an ambiguous room with dual visual verticals. In one of the test conditions, the subjects were cued to one of the two verticals and were instructed to cognitively reassign the apparent vertical to the cued orientation. When they have mentally adjusted their perception, two lines in a plus sign configuration appeared and the subjects had to evaluate which line was longer. The results showed that the line length appeared longer when it was aligned with the direction of the vertical currently perceived by the subject. This study provides a demonstration that top-down processing influences lower level visual processing mechanisms. In another test condition, the subjects had all perceptual cues available and the influence was even stronger.

The presented article covers the subject of creating one’s identity in a virtual reality of video games, in the perspective of LGBT characters and their influence on the exploration of the sexual identity of a gamer. It describes the means by which the user has the ability to experiment with and express their identity, putting an emphasis on the role of immersion and cultural reflection in this process. The fol-lowing presented issues concern the representation of sexual minorities and negative phenomena that are present in the virtual space (such as queerbaiting), which have an impact on both the user, as well as the game industry. It emphasizes the role of the appearance of LGBT characters in this medium, which potentially can positively influence the player and producer communities. In this article I also describe three examples of non-heteronormative characters and their importance to users and developers of the given games.

Immersive Technology

Over the years educators have adopted a variety of technologies in a bid to improve student engagement, interest and understanding of abstract topics taught in the classroom. There has been an increasing interest in immersive technology such as Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR). The ability of VR to bring ideas to life in three dimensional spaces in a way that is easy for students to understand the subject matter makes it one of the important tools available today for education. A key feature of VR is the ability to provide multi-sensory visuals and virtual interaction to students wearing a Head Mounted Display thus providing students better learning experience and connection to the subject matter. Virtual Reality has been used for training purposes in the health sector, military, workplace training, gamification and exploration of sites and countless others. With the potential benefits of virtual technology in visualizing abstract concepts in a realistic virtual world, this paper presents a plan to study the use of situated cognition theory as a learning framework to develop an immersive VR application that would be used to train and prepare students studying Telecommunications Engineering for the workplace. This paper presents a review of literature in the area of Virtual Reality in education, offers insight into the motivation behind this research and the planned methodology in carrying out the research.

The chapter explores the development of Elastic 3D Spaces as a research group, its span of inquiry, along with developments to date, using old and new technologies, including stereoscopy and augmented and virtual reality. Elastic 3D Spaces alludes to the space in front of a screen where images appear when using stereo to create 3D, where objects pop out of the screen. The perception of depth stretches if the viewer can move, hence elastic space. The chapter explores art projects whilst positioning the subject area involving both arts and science researchers and explains the topics it covers. Elastic 3D Spaces is interested in comparisons between 3D experiences and stereo 3D experiences from projection to virtual reality.

Fear Of Heights

Fear of flying is a common problem that many people have to face. As varied as the causes may be, all kinds of fears have many aspects in common. Much is known to us about fear, and the fields of psychology and psychiatry teach us that many times we can conquer fears simply by exposing the subject to the dreaded object. Human-Computer Interaction has branched even in this direction, including the treatment of phobias. With the help of Virtual Reality researchers around the world have recreated using a computer the way that psychologists and psychiatrists cure fears, adding a twist. Many times patients are supposed to go the extra mile and expose themselves, little by little, to what they are afraid of. Virtual Reality brings this type of exposure directly to the patient, with the comfort that such fear can be stopped at any time, since it is only a computer simulation. The most successful studies have been performed on arachnophobia, or the fear of spiders. There are also studies that deal with the fear of heights and the fear of public speaking. Some studies have also been performed on addressing the fear of flying using a virtual environment. This work is a review of such methods, and an explanation of the principles behind the motivation for these studies.
