Virtual locomotion technique (VLT) is a fundamental component of virtual reality (VR) systems that translates physical and controller inputs into virtual translational movements and viewpoint transitions. Poorly designed VLTs can result in discomfort, nausea, and reductions in task performance. Understanding the effectiveness of VLTs across various...

Objective. Evaluate the feasibility of Virtual Reality (VR) wayfinding training with aging adults, and examine the impact of the training on wayfinding performance. Design. Design involved wayfinding tasks in a study with three groups: active VR training, passive video training, and no training, assigned randomly. The training featured 5 tasks in a...

This study contributes to the ongoing exploration of methods to enhance the environmental design, cognitive function, and overall wellbeing, primarily focusing on understanding the modulation of human cognitive performance by artificial lighting conditions. In this investigation, participants (N=35) engaged with two distinct architectural contexts,...

This article presents a novel approach to assessing human reactions to indoor artificial lighting and lighting adjustment behavior. Participants (n = 27) were each exposed to 17 different lighting conditions via selected combinations of seven illuminance levels and seven different correlated color temperatures (CCTs) in a virtual office environment...

Virtual environments (VEs) are increasingly being used as a research platform for investigating human responses to environmental variables. While VEs provide tremendous advantages in terms of variable isolation and manipulation, and ease of data-collection, some researchers have expressed concerns about the ecological validity of VE-based findings;...

Emerging technologies such as virtual reality (VR) hold tremendous potential to improve the lives of older adults, including the opportunity to support social and cognitive engagement. However, this potential will only be realized if VR technologies and applications (apps) are well-designed, considering the needs, preferences, and abilities of olde...

Augmented reality (AR) technology has emerged as a promising solution to assist with wayfinding difficulties, bridging the gap between obtaining navigational assistance and maintaining an awareness of one's real-world surroundings. In this article, we present a systematic review of research literature related to AR navigation technologies. An in-de...

Virtual reality (VR) is increasingly being used as a research platform for investigating human responses to environmental variables. While VR provides tremendous advantages in terms of variable isolation and manipulation, and ease of data-collection, some researchers have expressed concerns about the ecological validity of VR-based findings. In the...

This paper presents a novel approach to assessing human lighting adjustment behavior and preference in diverse lighting conditions through the evaluation of emotional feedback and behavioral data using VR. Participants (n= 27) were exposed to different lighting (n=17) conditions with different levels of illuminance and correlated color temperature...

Investigating human responses to light can reveal important information with the potential to improve environmental design, circadian health, cognitive performance, and overall wellbeing. In this study, the researchers used VR immersion, EEG, and a machine-learning approach to better understand the relationship between brain activity and two import...

A novel approach was used to evaluate the impact of retail store layouts on consumer responses, by triangulating subjective feedback, behavioural data and electroencephalogram (EEG) data in the context of a virtual environment. Participants (n = 45) were assigned to one of three store layout conditions. While there were no significant differences i...

Virtual reality (VR) is increasingly used as a platform for social interaction, including as a means for elders to maintain engagement. However, not many empirical studies have been conducted to examine features of social VR that are most relevant to elders’ experiences. The current study qualitatively analyzed the behavior of older adults in a col...

Background and Objectives Virtual reality (VR) applications are increasingly being targeted toward older adults as a means to maintain physical and cognitive skills and to connect with others, especially during the COVID-19 era. Our knowledge about how older adults interact with VR is limited, however, since this is an emerging area and the related...

In order to face the widespread uncertainty characterizing the productive, financial, legislative, political and social contexts of Mogadishu, it is necessary to follow an alternative research approach for collecting reliable information concerning the manufacturing and construction fields. Despite of the lack of entrusted official information sour...

This study evaluated the impact of visual transparency vs. opaqueness in storefront window displays in relation to consumer responses and approach behavior. While there is extensive prior literature analyzing various design features in such exterior-facing displays, the ability to see through or around the window displays to observe the store inter...

Research examining older adults interactions with Virtual Reality (VR) and the impact of social VR experiences on outcomes such as social engagement has been limited, especially among older adults. This multi-site pilot study evaluated the feasibility and acceptability of a novel social virtual reality (VR) program that paired older adults from dif...

Virtual reality (VR) is increasingly used as a platform for social interaction, including as a means for older adults to maintain engagement. However, there has been limited research to examine the features of social VR that are most relevant to older adults experiences. The current study was conducted to qualitatively analyze the behavior of older...

Background and Objectives Exposure to nature and nature-based imagery has been shown to improve mood states and stave off cognitive decline in older adults. Even “micro-doses” of natural scenery can provide beneficial effects in situations where more extensive interactions with nature are not feasible. In the current study we evaluated the use of v...

Engaging with natural environments and representations of nature has been shown to improve mood states and reduce cognitive decline in older adults. The current study evaluated the use of virtual reality (VR) for presenting immersive 360 degree nature videos and a digitally designed interactive garden for this purpose. Fifty participants (age 60 pl...

Developments in cognitive neuroscience and brain imaging technologies make it possible to interface directly with the human brain using sensors. Brain activity during the navigation of built space is influenced by user perception and cognition in interaction with visual stimuli. This paper has a fourfold aim: (a) to elucidate the concept of design...

Wayfinding difficulties in healthcare facilities have been shown to increase anxiety among patients and visitors, to reduce staff operational efficiency, and to increase operational costs. There is evidence that wayfinding-oriented interior design features can mitigate these problems, but the robust evaluation of wayfinding design strategies is hin...

Wayfinding difficulties in healthcare facilities have been shown to increase anxiety among patients and visitors and reduce staff operational efficiency. Wayfinding-oriented interior design features have proven beneficial, but the evaluation of their performance is hindered by the unique nature healthcare facilities and the expense of testing diffe...

The realistic possibility of using non-metric digital cameras to achieve reliable 3D models has eased the application of photogrammetry in different domains. Documentation, conservation and dissemination of the Cultural Heritage (CH) can be obtained and implemented through virtual copies and replicas. Structure-from-Motion (SfM) photogrammetry has...

The impressive success of Structure-from-Motion Photogrammetry (SfM) has spread out the application of image-based 3D reconstruction to a larger community. In the field of Archeological Heritage documentation, this has opened the possibility of training local people to accomplish photogrammetric data acquisition in those remote regions where the or...
