TLDR
In this article, the effects on postural stability of varying field of view (FOV), image resolution, and scene content in an immersive visual display have been examined for evaluating presence and simulator sickness in virtual environments.Abstract:
Image quality issues such as field of view (FOV) and resolution are important for evaluating "presence" and simulator sickness (SS) in virtual environments (VEs) This research examined effects on postural stability of varying FOV, image resolution, and scene content in an immersive visual display Two different scenes (a photograph of a fountain and a simple radial pattern) at two different resolutions were tested using six FOVs (30, 60, 90, 120, 150, and 180 deg) Both postural stability, recorded by force plates, and subjective difficulty ratings varied as a function of FOV, scene content, and image resolution Subjects exhibited more balance disturbance and reported more difficulty in maintaining posture in the wide-FOV, high-resolution, and natural scene conditionsread more

How Immersive Is Enough? A Meta-Analysis of the Effect of Immersive Technology on User Presence
TL;DR: The current meta-analysis synthesizes decades of empirical research examining the effect of immersive system technology on user experiences of presence and finds that technological immersion has a medium-sized effect on presence.

Virtual reality induced symptoms and effects (VRISE): Comparison of head mounted display (HMD), desktop and projection display systems
TL;DR: Recommendations are offered concerning design and use of VR systems in order to minimise VRISE as the most notable finding was that of high inter- and intra-participant variability.

Effects of field of view on presence, enjoyment, memory, and simulator sickness in a virtual environment
TL;DR: The results indicated that presence, enjoyment and SS varied as a function of the display FOV, with higher SSQ and presence subscale scores with increasing FOV.

Augmenting the Field-of-View of Head-Mounted Displays with Sparse Peripheral Displays
Robert Xiao,Hrvoje Benko +1 more
TL;DR: The findings show that sparse peripheral displays are useful in conveying peripheral information and improving situational awareness, are generally preferred, and can help reduce motion sickness in nausea-susceptible people.

TL;DR: Investigating differences in energy expenditure and enjoyment across four game types found these games are less enjoyable than other more sedentary games, suggesting that they may be less likely to be played over time.

Differential Effects of Central Versus Peripheral Vision on Egocentric and Exocentric Motion Perception
TL;DR: Simultaneous presentation of conflicting central and peripheral optokinetics stimuli has shown that exocentric orientation depends on the peripheral stimulus whereas optokinetic nystagmus and egocentric motion perception rely on the center of the visual field.

Visual-Vestibular Interaction: Effects on Self-Motion Perception and Postural Control
Johannes Dichgans,Thomas Brandt +1 more
TL;DR: The self-motion illusion is a common visual illusion which allows inferences concerning visual-vestibular interaction as mentioned in this paper, and it may be perceived while gazing at moving clouds, streaming water, or when a train moves on the adjacent track in a railway station.

Flow structure versus retinal location in the optical control of stance.
TL;DR: In four experiments I found stronger sway response to flow having a largely lamellar structure that was presented to the retinal periphery than to more radially structured flow in the center.

TL;DR: The 2 most critical research issues identified were (a) standardization and use of measurement approaches for aftereffects and (b) identification and prioritization of sensorimotor discordances that drive aftere Affects.

The effects of pictorial realism, delay of visual feedback, and observer interactivity on the subjective sense of presence
TL;DR: According to subjects' verbal responses to a postexperiment Interview, pictorial realism was the least influential of the three variables examined and although some subjects reported an increase in the sense of presence over the course of the experiment, most said that it had remained unchanged or become weaker.
