Navigational tools are relied on to traverse unfamiliar grounds, but their use may come at a cost to situational awareness and spatial memory due to increased cognitive load. In order to test for a cost-benefit trade off in navigational cues, we implemented a variety of navigation cues known to facilitate target search and spatial knowledge acquisi...

Looking out over the Pacific Ocean or the Grand Canyon can lead to a sense of vastness. As a perceptual phenomenon, vastness poses a unique challenge because traditional measures of distance are not capable of explaining such large spatial extents. Vastness, however, may lead to a sense of awe, and awe, in turn, can dilate one’s experience of time....

Augmented Reality (AR) experiments are typically implemented in controlled conditions that are guided by experimenters. The paucity of research on remote AR experiments leads to difficulties for many researchers when conducting remote user studies. Our work provides a preliminary investigation of spatial perception in AR via mobile devices. The ini...

Full-text available
Although it is commonly accepted that depth perception in augmented reality (AR) displays is distorted, we have yet to isolate which properties of AR affect people’s ability to correctly perceive virtual objects in real spaces. From prior research on depth perception in commercial virtual reality, it is likely that ergonomic properties and graphica...
Article
Everything in our environment moves through both space and time, and to effectively act we must be aware of both spatial and temporal elements in relation to our own body. Thus, perception of space and time have an intimate relationship. Walsh’s a theory of magnitude (ATOM) suggests that space and time perception rely on a general magnitude system...

Spatial experience in childhood is a factor in the development of spatial abilities. In this study, we assessed whether American and Faroese participants’ (N = 246, Mage = 19.31 years, 151 females) early spatial experience and adult spatial outcomes differed by gender and culture, and if early experience was related to adult performance and behavio...

The information provided to a person's visual system by extended reality (XR) displays is not a veridical match to the information provided by the real world. Due in part to graphical limitations in XR head-mounted displays (HMDs), which vary by device, our perception of space may be altered. However, we do not yet know which properties of virtual...
Conference Paper
Full-text available
Although Augmented Reality (AR) can be easily implemented with most smartphones and tablets today, the investigation of distance perception with these types of devices has been limited. In this paper, we question whether the distance of a virtual human, e.g., avatar, seen through a smartphone or tablet display is perceived accurately. We also inves...

Abstract Background: With Augmented Reality (AR), people interact with virtual content displayed within the real environment. AR cues and objects can be used to conduct rigorously controlled experiments to understand the mechanisms underlying human perception of the environment. Prior work has investigated whether the addition of AR cues to the re...
Article
Full-text available
Virtual objects in augmented reality (AR) often appear to float atop real world surfaces, which makes it difficult to determine where they are positioned in space. This is problematic as many applications for AR require accurate spatial perception. In the current study, we examine how the way we render cast shadows--which act as an important monocu...
Article
Augmented reality ( AR ) is important for training complex tasks, such as navigation, assembly, and medical procedures. The effectiveness of such training may depend on accurate spatial localization of AR objects in the environment. This article presents two experiments that test egocentric distance perception in augmented reality within and at the...
Conference Paper
Full-text available
Augmented reality is standard on many modern smartphone platforms. The distance of virtual objects seen through the smartphone display should be perceived accurately for easy interaction with virtual objects with high fidelity. We investigate whether distance perception through mobile augmented reality devices is affected by an animated avatar. The...

We investigated two judgments of action capabilities with virtual objects presented through smartphones: passing through an aperture and stepping over a gap. The results showed that users were conservative in their affordance judgments for the two actions, but that judgments became more accurate with training by AR cues. In the post-cue trials, pas...
Article
Full-text available
Measures of perceived affordances—judgments of action capabilities—are an objective way to assess whether users perceive mediated environments similarly to the real world. Previous studies suggest that judgments of stepping over a virtual gap using augmented reality (AR) are underestimated relative to judgments of real-world gaps, which are general...
Article
Studies in the psychology of visual expertise have tended to focus on a limited set of expert domains, such as radiology and athletics. Conclusions drawn from these data indicate that experts use parafoveal vision to process images holistically. In this study, we examined a novel, as-of-yet-unstudied class of visual experts—architects—expecting sim...
Article
The relative contribution of different sources of information for spatial updating – keeping track of one’s position in an environment – has been highly debated. Further, children and adults may differ in their reliance on visual versus body-based information for spatial updating. In two experiments, we tested children (age 10–12 years) and young a...
Article
Successful performance on the water-level task, a common measure of spatial perception, requires adopting an environmental, rather than object-centered, spatial frame of reference. Use of this strategy has not been systematically studied in prepubertal children, a developmental period during which individual differences in spatial abilities start t...
Article
Full-text available
Both visual and body-based (vestibular and proprioceptive) information contribute to spatial updating, or the way a navigator keeps track of self-position during movement. Research has tested the relative contributions of these sources of information and found mixed results, with some studies demonstrating the importance of body-based information,...

Full-text available
ABSTRACT: Spatial updating is the ability to maintain knowledge of one’s spatial position in the environment and in humans, typically involves both visual and motor cues for self-motion. Previous research has shown developmental differences in sensorimotor dependency for spatial cognition. Some studies show greater visual dependency in children com...
Article
Full-text available
Affordances are possibilities for action that depend on both an observer's capabilities and the properties of the environment. Immersive Virtual Environments (IVEs) have been used to examine affordances in adults, demonstrating that judgments about action capabilities are made similarly to the real world. However, less is known about affordance jud...

The creation of realistic self-avatars that users identify with is important for many virtual reality applications. However, current approaches for creating biometrically plausible avatars that represent a particular individual require expertise and are time-consuming. We investigated the visual perception of an avatar’s body dimensions by asking m...
Article
Object perception occurs within a dynamic world, where the environment and the observer (both body and eyes) are continually moving, shifting and changing. We seek to characterize and quantify this process from a perspective accounting for the interconnected system of motion in the environment, the perceiver and the eye, unfolding through time. Spe...

Recent advancements in augmented reality (AR) have led to the development of several applications in domains such as architecture, engineering, and medical training. Typically, these applications present users with 3D virtual images in real environments that would not easily be portrayed otherwise (e.g., floor plans, arteries, etc.). The way users...
Article
Men show a consistent spatial navigation advantage over women, which is often attributed to their increased use of survey spatial strategies. But what about men’s navigation gives them an advantage? One possibility is that the way in which men explore environments is fundamentally different, leading to better navigational performance. To test this...

Research has established that GPS use negatively affects environmental learning and navigation in laboratory studies. Furthermore, the ability to mentally rotate objects and imagine locations from other perspectives (both known as spatial transformations) is positively related to environmental learning. Using previously validated spatial transforma...

Conference Paper
Full-text available
Augmented reality (AR) technologies have the potential to provide individuals with unique training and visualizations, but the effectiveness of these applications may be influenced by users' perceptions of the distance to AR objects. Perceived distances to AR objects may be biased if these objects do not appear to make contact with the ground plane...
Conference Paper

It is an open question as to whether people perceive and act in augmented reality environments in the same way that they do in real environments. The current work investigated participants' judgments of whether or not they could act on an obstacle portrayed with augmented reality. Specifically, we presented gaps of varying widths and depths to part...

Interfaces play a crucial role in a device’s success or failure. Although visual aspects generally receive more attention, findings from sonic interaction design increasingly illustrate the importance of auditory aesthetics in creating desirable products. Here we show that small changes to the amplitude envelope (i.e., “sound shape”) of tones affec...

Past research shows consistent sex differences in survey-based spatial knowledge and wayfinding strategy. State anxiety may help to explain some of these differences. The current study tested if and how state anxiety influences sex differences in spatial learning during navigation. We used a virtual desktop spatial learning task and manipulated sta...

The creation or streaming of photo-realistic self-avatars is important for virtual reality applications that aim for perception and action to replicate real world experience. The appearance and recognition of a digital self-avatar may be especially important for applications related to telepresence, embodied virtual reality, or immersive games. We...
Conference Paper
The utility of mediated environments increases when environmental scale (size and distance) is perceived accurately. We present the use of perceived affordances---judgments of action capabilities---as an objective way to assess space perception in an augmented reality (AR) environment. The current study extends the previous use of this methodology...

Children have begun to use virtual reality with increasing frequency ; however, it is uncertain how immersive virtual environments affect a child's understanding of three dimensional space. We present preliminary work evaluating the spatial memory of children across real and virtual worlds. We assess 10 children (aged 9-12) and 9 teenagers (aged 16...
Article
When humans and animals navigate through environments, they form spatial memories important for supporting subsequent recall of locations relative to their own position and orientation, as well as to other object locations in the environment. The goal of the current study was to examine whether individual differences in initial exploration of a lar...

We investigated whether anxiety influences perceptual-motor calibration in a braking to avoid a collision task. Participants performed either a discrete braking task (Experiment 1) or a continuous braking task (Experiment 2), with the goal of stopping before colliding with a stop sign. Half of participants performed the braking task after an anxiet...

The previous body image literature has focused on how females perceive their body weight. We investigated potential gender differences in the use of visual cues (shape, texture) to estimate own body weight. A full-body scanner was used to capture each participant’s own body geometry and colour information and a set of nine personalized 3D virtual b...

Previous research demonstrated that estimates of others’ body sizes are biased towards the average body size in the population (Cornelissen, Gledhill, Cornelissen Tovée, 2016). Bodies in the environment not only influence the internal reference of what is perceived as average or “normal”, but also play an essential role in self-body size evaluation...

“Vast” is a word often applied to environmental terrain that is perceived to have large spatial extent. This judgment is made even at viewing distances where traditional metric depth cues are not useful. This paper explores the perceptual basis of vast experience, including reliability and visual precursors. Experiment 1 demonstrated strong agreeme...

It may be evolutionarily adaptive for parents to imagine a dangerous outcome when offspring have potential to be harmed. However, its possible that this only generalizes to harm avoidant individuals, a trait-level individual difference measured by a subset of the multidimensional personality questionnaire. Harm avoidance has previously been shown t...
