“…The authors conclude that visual display type influences motor behaviour in their game, thus providing important guidelines for the development of virtual reality applications for home and clinic use. Results as those just reported are also confirmed by other studies, like that shown in [39] regarding a virtual simulated store, in which the advantages of immersive virtual reality compared to conventional desktop technology are pointed out in terms of interaction, usability, and naturalness. In the latter context, several applications are available to assess, by feasible and valid scenarios, everyday memory in complex conditions that are close to real-life situations, an example is reported in [40].…”

In recent years, advancements in human–computer interaction (HCI) have enabled the development of versatile immersive devices, including Head-Mounted Displays (HMDs). These devices are usually used for entertainment activities as video-gaming or augmented/virtual reality applications for tourist or learning purposes. Actually, HMDs, together with the design of ad-hoc exercises, can also be used to support rehabilitation tasks, including neurocognitive rehabilitation due to strokes, traumatic brain injuries, or brain surgeries. In this paper, a tool for immersive neurocognitive rehabilitation is presented. The tool allows therapists to create and set 3D rooms to simulate home environments in which patients can perform tasks of their everyday life (e.g., find a key, set a table, do numerical exercises). The tool allows therapists to implement the different exercises on the basis of a random mechanism by which different parameters (e.g., objects position, task complexity) can change over time, thus stimulating the problem-solving skills of patients. The latter aspect plays a key role in neurocognitive rehabilitation. Experiments obtained on 35 real patients and comparative evaluations, conducted by five therapists, of the proposed tool with respect to the traditional neurocognitive rehabilitation methods highlight remarkable results in terms of motivation, acceptance, and usability as well as recovery of lost skills.

“…Given the authenticity of the shopping behaviours found in this study, readers may naturally wish to know how similarly authentic shopping environments may be constructed. The immersive elements used to generate authentic shopper behaviour in the present study were high-resolution visual immersion with individual object modelling, naturalness of functionality for navigation and product inspection, extensive interactivity with the virtual environment, and an authentic audible environment (Schnack et al, 2019). Designers of VSS systems for shopper research may therefore be advised to include these elements by using (a) HMDs that track head movement and isolate a user's vision from the physical environment, creating a more convincing feeling of presence in the virtual environment (Hendrix & Barfield, 1996); (b) motion-tracked controllers allowing free product movement that improves naturalness compared with traditional mouse and keyboard interfaces (Seibert & Shafer, 2017);…”

“…Extending previous studies, Schnack, Wright, and Holdershaw (2019) compared telepresence in a traditional desktop VSS with telepresence in an immersive VSS using the latest iVR technology. Their results confirmed that the iVR-generated store environment led to higher levels of telepresence compared with desktop technology, implying that VSSs using iVR technology (immersive VSS) will yield greater similarity between shoppers' virtual and actual shopping behaviours.…”

Shopper research has long been undertaken with physical simulated stores and desktop‐operated virtual stores. However, recent developments in motion‐tracked virtual reality offer a range of new possibilities for research using immersive walk‐around virtual simulated stores. To date, there is little knowledge published on the authenticity of shopper behaviour in such immersive virtual environments. The present study therefore reports exploratory results from 153 multicategory shopping trips conducted in an immersive virtual convenience store. Observed shopper metrics and theoretical effects are compared with equivalent data obtained from published sources and found to be consistent across all measures. Specifically, shoppers purchase a plausible share of private label brands, more private label brands in lower consumption pleasure product categories, more products from higher compared with lower shelf positions, make a plausible proportion of impulsive purchases, and spend less time inspecting familiar versus unfamiliar brands. Further, time in‐store, total spending, and product handling time are higher for women than for men. These exploratory findings show that participants continue to exhibit realistic shopper behaviours in an immersive virtual simulated store. Such stores are therefore a cost‐effective alternative to other methods for measuring consumer behaviour. They offer significant potential for innovative experimental designs in consumer research, as well as potential for future use as a digital shopping channel.

“…The ability to freely navigate through VE and interact with virtual objects, when their physics is realistically modelled, greatly contributes to the sense of presence [4,5]. Stronger SoP is achieved when a user embodies his or her virtual avatar, which realistically depicts the user's movements with the help of motion capture technology [6]. The wording of the given instruction before the VE exposure [2] and the personality traits of the individual, such as the ability to immerse in various contexts, the ability to ignore distractions, the feeling of "being captivated," the intensity of emotions provoked by the content, and the frequency of immersions into the content [7] also affect the strength of the sense of presence.…”

The evolution of virtual reality (VR) technologies requires setting boundaries of its use. In this study, 3 female participants were experiencing VR scenarios with stressful content and their activity of the autonomic nervous system and EEG were recorded. It has been discovered that virtual reality can evoke acute stress reactions accompanied by activation of the sympathetic nervous system and a decrease in the activity of the parasympathetic nervous system. The high-stress response is accompanied by a decrease in the power of the EEG, and, on the contrary, the activation of the avoidance reaction is accompanied by an increase in the power of the EEG alpha waves. Therefore, the use of stressful VR content can cause high emotional stress to a user and restrictions should be considered.
