A Survey on Simulation Sickness in Virtual Environments
Preprints (www.preprints.org) | NOT PEER-REVIEWED | Posted: 7 July 2021 doi:10.20944/preprints202107.0167.v1 1 A Survey on Simulation Sickness in Virtual Environments Factors, Design and Best Practices Ananth N. Ramaseri Chandra, Fatima El Jamiy, Hassan Reza School of Electrical Engineering and Computer Science University of North Dakota Grand Forks, ND 58202 Email: ananthnag.ramaserich, [email protected] Abstract—Virtual Reality(VR) is an emerging technology with a broad range of application in training, entertainment, and business. To maximize the potentials of virtual reality as a medium, the unwelcome feeling of simulation sickness needs to be minimized. Even with advancements in VR, the usability concerns are barriers for a wide-spread acceptance. Several factors (hardware, software, human) play a part towards a pleasant VR experience. The reviewed scientific articles are mostly part of documents indexed in digital libraries. In this paper, we review the potential factors which cause simulation sickness and minimize the usability of virtual reality systems. We review the best practices from a developer’s perspective and some of the safety measures a user must follow while using the VR systems from existing research. Even after following some of the guidelines and best practices VR environments do not guarantee a pleasant experience for users. Limited research in VR environments towards requirement specification, design and development for maximum usability and adaptability was the main motive for this work. Index Terms—Virtual reality(VR), Virtual environment, Simulation sickness, Head mounted display(HMD), Usability, Design, Guidelines, User F 1 INTRODUCTION its history, and how simulation sickness is a usability issues for virtual reality systems. -

Virtual Reality Sickness During Immersion: an Investigation of Potential Obstacles Towards General Accessibility of VR Technology
Examensarbete 30hp August 2016 Virtual Reality sickness during immersion: An investigation of potential obstacles towards general accessibility of VR technology. A controlled study for investigating the accessibility of modern VR hardware and the usability of HTC Vive’s motion controllers. Dongsheng Lu Abstract People call the year of 2016 as the year of virtual reality. As the world leading tech giants are releasing their own Virtual Reality (VR) products, the technology of VR has been more available than ever for the mass market now. However, the fact that the technology becomes cheaper and by that reaches a mass-market, does not in itself imply that long-standing usability issues with VR have been addressed. Problems regarding motion sickness (MS) and motion control (MC) has been two of the most important obstacles for VR technology in the past. The main research question of this study is: “Are there persistent universal access issues with VR related to motion control and motion sickness?” In this study a mixed method approach has been utilized for finding more answers related to these two important aspects. A literature review in the area of VR, MS and MC was followed by a quantitative controlled study and a qualitative evaluation. 32 participants were carefully selected for this study, they were divided into different groups and the quantitative data collected from them were processed and analyzed by using statistical test. An interview was also carried out with all of the participants of this study in order to gather more details about the usability of the motion controllers used in this study. -
Analysis of User Preferences for Robot Motions in Immersive Telepresence
Analysis of User Preferences for Robot Motions in Immersive Telepresence Katherine J. Mimnaugh1, Markku Suomalainen1, Israel Becerra2, Eliezer Lozano2, Rafael Murrieta-Cid2, and Steven M. LaValle1 Abstract— This paper considers how the motions of a telep- resence robot moving autonomously affect a person immersed in the robot through a head-mounted display. In particular, we explore the preference, comfort, and naturalness of elements of piecewise linear paths compared to the same elements on a smooth path. In a user study, thirty-six subjects watched panoramic videos of three different paths through a simulated museum in virtual reality and responded to questionnaires regarding each path. Preference for a particular path was influ- enced the most by comfort, forward speed, and characteristics of the turns. Preference was also strongly associated with the users’ perceived naturalness, which was primarily determined by the ability to see salient objects, the distance to the walls and objects, as well as the turns. Participants favored the paths that had a one meter per second forward speed and rated the path with the least amount of turns as the most comfortable. I.

Virtual Reality Sickness Mitigation Methods: a Comparative Study in a Racing Game
Virtual Reality Sickness Mitigation Methods: A Comparative Study in a Racing Game RONGKAI SHI, Xi’an Jiaotong-Liverpool University, China HAI-NING LIANG∗, Xi’an Jiaotong-Liverpool University, China YU WU, Xi’an Jiaotong-Liverpool University, China DIFENG YU, University of Melbourne, Australia WENGE XU, Xi’an Jiaotong-Liverpool University, China Using virtual reality (VR) head-mounted displays (HMDs) can induce VR sickness. VR sickness can cause strong discomfort, decrease users’ presence and enjoyment, especially in games, shorten the duration of the VR experience, and can even pose health risks. Previous research has explored different VR sickness mitigation methods by adding visual effects or elements. Field of View (FOV) reduction, Depth of Field (DOF) blurring, and adding a rest frame into the virtual environment are examples of such methods. Although useful in some cases, they might result in information loss. This research is the first to compare VR sickness, presence, workload to complete a search task, and information loss of these three VR sickness mitigation methods in a racing game with two levels of control. To do this, we conducted a mixed factorial user study (N = 32) with degree of control as the between-subjects factor and the VR sickness mitigation techniques as the within-subjects factor. Participants were required to find targets with three difficulty levels while steering or not steering acarin virtual environment. Our results show that there are no significant differences in VR sickness, presence and workload among these techniques under two levels of control in our VR racing game. We also found that changing FOV dynamically or using DOF blur effects would result in information loss while adding a target reticule as a rest frame would not. -
