Position And Orientation

Exoskeletons are an external structural mechanism with joints and links that work in tandem with the user, which increases, reinforces, or restores human performance. Virtual Reality can be used to produce environments, in which the intensity of practice and feedback on performance can be manipulated to provide tailored motor training. Will it be possible to combine both technologies and have them synchronized to reach better performance? This paper consists of the kinematics analysis for the position and orientation synchronization between an n DoF upper-limb exoskeleton pose and a projected object in an immersive virtual reality environment using a VR headset. To achieve this goal, the exoskeletal mechanism is analyzed using Euler angles and the Pieper technique to obtain the equations that lead to its orientation, forward, and inverse kinematic models. This paper extends the author’s previous work by using an early stage upper-limb exoskeleton prototype for the synchronization process.

Human Factors Research

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.

Abstract Introduction : Today's society is influenced by Information and Communication Technologies. Toys that were once built by hand have been reinterpreted and have become highly commercialized products. In this context, games using Augmented Reality (AR) and Virtual Reality (VR) technologies are present in the everyday lives of children, youth and adults. Objective : To investigate how Physical Education professionals in Brazil have been making use of AR and VR games to benefit their work. Materials and methods : We only included studies that addressed exercise or physical activity using AR or VR games. We searched the databases of Virtual Health Library (VHL) and Scientific Electronic Library Online (SciELO), using the words augmented reality, virtual reality, exergames, Wii and serious games. Results : Nineteen articles were included in the systematic review. The most frequently used device was the Nintendo(r) Wii, with over 25 different kinds of games. With regard to the subjects of the studies, four studies were conducted with healthy individuals (mean = 65.7), three with patients with Parkinson's disease (mean = 18.0), three with elderly women (mean = 7.7) and two with patients with stroke injury (mean = 6.0). Conclusion : Many physical therapists and occupational therapists use serious games with AR or VR technologies as another work tool, especially for rehabilitation practices. The fact that these technologies are also used in Physical Education classes in Brazil indicates that electronic games are available and can be a tool that can contribute to the widespread adoption of exercise as an enjoyable form of recreation.

Creativity And Innovation

This article highlights virtual reality (VR) as perhaps the safest, most fully developed of the emerging technologies of cognitive enhancement and as an underused tool for the enhancement of creativity in particular. We argue that researchers, educators, trainers, designers, managers, and others concerned with innovation should be more informed about virtual reality technologies (VRTs) both because of their widespread and growing accessibility and because of the significant, synergistic contributions they can make to human performance and understanding. We present a brief consultative survey exploring the potential use of virtual worlds (VWs) such as Second Life among a group of professionals (N= 20) working in the area of creativity and innovation training. In addition to providing some useful perspectives and creativity strategies for implementation, results suggest that the possibilities represented by VRTs may not be fully appreciated by those who could make the most use of them. We argue that VRTs offer a cost-effective means of implementing and optimizing nearlyallconventional individual and collaborative creativity enhancement techniques while also offering potent new possibilities and combinations not available by other means. Thus, we outline five ways VR can be used to enhance creativity and problem solving: (a) by changing aspects of the self and self-perception; (b) by optimizing interactions and collaboration with others; (c) by optimizing environmental conditions and influences; (d) by facilitating guidance orgamificationof the problem-solving process; and (e) by offering an arena for the integration of other technologies of creativity enhancement such as pharmacological enhancement, brain stimulation, and neurofeedback. The article ends with a discussion of this technological convergence within the growing sciences of innovation and cognitive enhancement.

Telepresence systems should be designed to assist the human operator as much as possible to fulfill his task. In order to support the user concerning the visual modality, a system was designed that presents virtual reality images combined together with camera images captured at the remote teleoperator environment. In this work, two experiments were conducted. In the first, it was shown that presenting a widened field of view to the human operator enhances the human performance and the feeling of telepresence. In the second, it was examined how the transition between video and virtual views has to be designed. Relevant criteria of this transition were chosen and the results show that the operator's rating of quality, feeling of telepresence, and situation awareness are positively affected by variations of the transition parameters. Furthermore, a trade-off between the rating of quality and the situation awareness was observed. A parameter selection scheme is presented which can serve as a design guideline for combining video and virtual views depending on the desired application.
