Introduction Social media has created opportunities for children to gather social support online (Blackwell et al., 2016; Gonzales, 2017; Jackson, Bailey, & Foucault Welles, 2018; Khasawneh, Rogers, Bertrand, Madathil, & Gramopadhye, 2019; Ponathil, Agnisarman, Khasawneh, Narasimha, & Madathil, 2017). However, social media also has the potential to expose children and adolescents to undesirable behaviors. Research showed that social media can be used to harass, discriminate (Fritz & Gonzales, 2018), dox (Wood, Rose, & Thompson, 2018), and socially disenfranchise children (Page, Wisniewski, Knijnenburg, & Namara, 2018). Other research proposes that social media use might be correlated to the significant increase inmore »
Assessing vignetting as a means to reduce VR sickness during amplified head rotations
Redirected and amplified head movements have the potential to
provide more natural interaction with virtual environments (VEs)
than using controller-based input, which causes large discrepancies
between visual and vestibular self-motion cues and leads to
increased VR sickness. However, such amplified head movements
may also exacerbate VR sickness symptoms over no amplification.
Several general methods have been introduced to reduce VR sickness
for controller-based input inside a VE, including a popular
vignetting method that gradually reduces the field of view.
In this paper, we investigate the use of vignetting to reduce VR
sickness when using amplified head rotations instead of controllerbased
input. We also investigate whether the induced VR sickness
is a result of the user’s head acceleration or velocity by introducing
two different modes of vignetting, one triggered by acceleration and
the other by velocity. Our dependent measures were pre and post
VR sickness questionnaires as well as estimated discomfort levels
that were assessed each minute of the experiment. Our results show
interesting effects between a baseline condition without vignetting,
as well as the two vignetting methods, generally indicating that
the vignetting methods did not succeed in reducing VR sickness for
most of the participants and, instead, lead to a significant increase.
We discuss the results and potential explanations of our findings.

Third-person is a popular perspective for video games, but virtual reality (VR) seems to be primarily experienced from a first-person point of view (POV). While a first-person POV generally offers the highest presence; a third-person POV allows users to see their avatar; which allows for a better bond, and the higher vantage point generally increases spatial awareness and navigation. Third-person locomotion is generally implemented using a controller or keyboard, with users often sitting down; an approach that is considered to offer a low presence and embodiment. We present a novel thirdperson locomotion method that enables a high avatar embodiment bymore »

Background: Drivers gather most of the information they need to drive by looking at the world around them and at visual displays within the vehicle. Navigation systems automate the way drivers navigate. In using these systems, drivers offload both tactical (route following) and strategic aspects (route planning) of navigational tasks to the automated SatNav system, freeing up cognitive and attentional resources that can be used in other tasks (Burnett, 2009). Despite the potential benefits and opportunities that navigation systems provide, their use can also be problematic. For example, research suggests that drivers using SatNav do not develop as much environmentalmore »

The number of people who own a virtual reality (VR) head-mounted display (HMD) has reached a point where researchers can readily recruit HMD owners to participate remotely using their own equipment. However, HMD owners recruited online may differ from the university community members who typically participate in VR research. HMD owners (n=220) and non-owners (n=282) were recruited through two online work sites-Amazon's Mechanical Turk and Prolific-and an undergraduate participant pool. Participants completed a survey in which they provided demographic information and completed measures of HMD use, video game use, spatial ability, and motion sickness susceptibility. In the context of themore »

Virtual reality sickness typically results from visual-vestibular conflict. Because self-motion from optical flow is driven most strongly by motion at the periphery of the retina, reducing the user’s field-of-view (FOV) during locomotion has proven to be an effective strategy to minimize visual vestibular conflict and VR sickness. Current FOV restrictor implementations reduce the user’s FOV by rendering a restrictor whose center is fixed at the center of the head mounted display (HMD), which is effective when the user’s eye gaze is aligned with head gaze. However, during eccentric eye gaze, users may look at the FOV restrictor itself, exposing themmore »
