Virtual environments (VEs) can be infinitely large, but movement of the virtual reality (VR) user is constrained by the surrounding real environment. Teleporting has become a popular locomotion interface to allow complete exploration of the VE. To teleport, the user selects the intended position (and sometimes orientation) before being instantly transported to that location. However, locomotion interfaces such as teleporting can cause disorientation. This experiment explored whether practice and feedback when using the teleporting interface can reduce disorientation. VR headset owners participated remotely. On each trial of a triangle completion task, the participant traveled along two path legs through a VE before attempting to point to the path origin. Travel was completed with one of two teleporting interfaces that differed in the availability of rotational self-motion cues. Participants in the feedback condition received feedback about their pointing accuracy. For both teleporting interfaces tested, feedback caused significant improvement in pointing performance, and practice alone caused only marginal improvement. These results suggest that disorientation in VR can be reduced through feedback-based training. 

There are several barriers to research translation from academia to the broader HCI/UX community and specifically for the design of virtual reality applications. Because of the inaccessibility of evidence-based VR research to industry practitioners, freely-available blog-style media on platforms like Medium, where there is no moderation, is more available, leading to the spread of misinformation. The Design of Virtual Environments (DOVE) website, attempts to address this challenge by offering peer reviewed unbiased VR research, translating it for the layperson, and opening it up to contribution, synthesis and discussion through forums. This paper describes the initial user centered design process for the DOVE website through informal expert interviews, competitive analysis and heuristic review to redesign the site navigation, translation content, and incentivized forms for submission of research. When completed, the DOVE website will aid the translation of AR/VR research to practice. 

Teleporting is a popular interface for locomotion through virtual environments (VEs). However, teleporting can cause disorientation. Spatial boundaries, such as room walls, are effective cues for reducing disorientation. This experiment explored the characteristics that make a boundary effective. All boundaries tested reduced disorientation, and boundaries representing navigational barriers (e.g., a fence) were no more effective than those defined only by texture changes (e.g., flooring transition). The findings indicate that boundaries need not be navigational barriers to reduce disorientation, giving VE designers greater flexibility in the spatial cues to include. 

According to the CDC, over three thousand people die every year from drowning in the United States. Many of these fatalities are preventable with properly trained lifeguards. Traditional lifeguard training relies on videos and mock rescues. While these methods are important, they have their shortcomings. Videos are static and do not build muscle memory. Mock rescues are labor-intensive and potentially put others in danger. Virtual reality (VR) can be used as an alternative training tool, building muscle memory in a fully controlled and safe environment. With full control over variables such as weather, population, and other distractions, lifeguards can be better equipped to respond to any situation. The single most important aspect of life guarding is finding the victim. This head rotation skill can be practiced and perfected in VR before guards ever get onto the stand. It also allows guards to practice in uncommon but nevertheless dangerous conditions such as fog and large crowds. VR also allows the user to get immediate feedback about performance and where they can improve.
