A Review of Requirements and Approaches for Realistic Visual Perception in Virtual Reality

Abstract

The amount of new virtual reality input and output devices being developed is enormous. Those peripherals offer novel opportunities and possibilities in the industrial context, especially in the product development process. Nevertheless, virtual reality has to face several problems, counteracting reliable use of the technology, especially in ergonomic and aesthetic assessments. In particular, the discrepancies in perception between the real world and virtual reality are of great importance.Therefore, we discuss these most important issues of current virtual reality technology and highlight approaches to solve them. First, we illustrate the use cases of VR in the product development process. In addition, we show which hardware is currently available for professional use and which issues exist with regard to visual perception and interaction. Derived from the depiction of a perfect virtual reality, we define the requirements to address visual perception and interaction. Subsequently we discuss approaches to solve the issues regarding visual perception and evaluate their suitability to enhance the use of virtual reality technology in engineering design.

Simplified Virtual Reality System Can Be Used to Evaluate the Temporal Discrimination Ability in Softball Batting as in the Real Environment

“…In this study as well, wearing the HMD might reduce the stability of the batter's movement and decrease their swing speed, making their swing onset earlier for proper timing of the bat-ball contact. Other studies have also reported underestimation of distances in VR due to the HMD's weight and limited FOV (Renner et al, 2013 ; Gerschütz et al, 2019 ) and the invisibility of one's own body (Naceri et al, 2009 ). Some of our participants also reported that “it was difficult to perceive the distance from the pitcher.” If a batter perceives the distance to the pitcher as closer than it actually is, this misperception may cause early swing onset.…”

“…Players and coaches can easily use HMDs in the field at any time and place. Despite these advantages, it has also been reported that the HMD has some issues, such as reduced movement speed and stability (Pastel et al, 2020 ; Almajid et al, 2021 ; Chen et al, 2021 ), distance underestimation (Renner et al, 2013 ; Gerschütz et al, 2019 ), and cybersickness (Rebenitsch and Owen, 2016 ; Kourtesis et al, 2019 ) caused by technical limitations such as the narrow field of view (FOV), the weight of the device, and the lack of visibility of one's own body. To determine the existence of these issues, we also conducted a questionnaire investigation about the user experience and the cybersickness of the VR system.…”

A Novel Experimental Design of a Real-Time Vr Tracking Device

“…Various current design methods and tools rely on technologies that enable new opportunities and possibilities in product development. Virtual Reality (VR) technology gains wider adoption at different stages of engineering design and product development (Carulli et al, 2018;Horvat et al, 2019;Gerschütz et al, 2019). Consequently, evolving interaction requirements in design and product development for VR are essential for the adoption, especially in the case of engineering design applications.…”

“…Compact, precise, and wearable devices are essential to match increasingly complex interaction requirements of VR systems utilized on different stages of in engineering design. Such requirements are valid for all design stages (Gerschütz et al, 2019). In this paper we focus on motion tracking devices for VR.…”

The Validity of Molecular Geometry Based Virtual Reality to Improve Student Visual-Spatial Intelligence in New Normal Era

“…The visual-spatial intelligence tests that have been conducted obtained an average test score of 32.57, the value is still relatively low, so it needs to be improved so that students can predict a virtual object to be read correctly. The development of VR technology can help students improve visual-spatial intelligence because in VR there are two important things in its development: spatial and visual prestige (Gerschütz, 2019).…”
