Title: Navigation Tasks in Desktop VR Environments to Improve the Spatial Orientation Skill of Building Engineers
Virtual reality is a powerful tool for teaching 3D digital technologies in building engineering, as it facilitates the spatial perception of three-dimensional space. Spatial orientation skill is necessary for understanding 3D space. With VR, users navigate through virtually designed buildings and must be constantly aware of their position relative to other elements of the environment (orientation during navigation). In the present study, 25 building engineering students performed navigation tasks in a desktop-VR environment workshop. Performance of students using the desktop-VR was compared to a previous workshop in which navigation tasks were carried out using head-mounted displays. The Perspective Taking/Spatial Orientation Test measured spatial orientation skill. A questionnaire on user experience in the virtual environment was also administered. The gain in spatial orientation skill was 12.62%, similar to that obtained with head-mounted displays (14.23%). The desktop VR environment is an alternative to the HMD-VR environment for planning strategies to improve spatial orientation. Results from the user-experience questionnaire showed that the desktop VR environment strategy was well perceived by students in terms of interaction, 3D visualization, navigation, and sense of presence. Unlike in the HDM VR environment, student in the desktop VR environment did not report feelings of fatigue or dizziness.  more » « less

    Virtual reality games have grown rapidly in popularity since the first consumer VR head-mounted displays were released in 2016, however comparatively little research has explored how this new medium impacts the experience of players. In this paper, we present a study exploring how user experience changes when playing Minecraft on the desktop and in immersive virtual reality. Fourteen players completed six 45 minute sessions, three played on the desktop and three in VR. The Gaming Experience Questionnaire, the i-Group presence questionnaire, and the Simulator Sickness Questionnaire were administered after each session, and players were interviewed at the end of the experiment. Participants strongly preferred playing Minecraft in VR, despite frustrations with using teleporation as a travel technique and feelings of simulator sickness. Players enjoyed using motion controls, but still continued to use indirect input under certain circumstances. This did not appear to negatively impact feelings of presence. We conclude with four lessons for game developers interested in porting their games to virtual reality.

    The immersion of virtual reality (VR) can impact user perceptions in numerous forms, even racial bias and embodied experiences. These effects are often limited to head-mounted displays (HMDs) and other immersive technologies that may not be inclusive to the general population. This paper investigates racial bias and embodiment on a less immersive but more accessible medium: desktop VR. A population of participants (n = 158) participated in a desktop simulation where they embodied a virtual avatar and interacted with virtual humans to determine if desktop embodiment is induced and if there is a resulting effect on racial bias. Our results indicate that desktop embodiment can be induced at low levels, as measured by an embodiment questionnaire. Furthermore, one’s implicit bias may actually influence embodiment, and the experience and perceptions of a desktop VR simulation can be improved through embodied avatars. We discuss these findings and their implications in the context of stereotype activation and existing literature in embodiment.

    During active shooter events or emergencies, the ability of security personnel to respond appropriately to the situation is driven by pre-existing knowledge and skills, but also depends upon their state of mind and familiarity with similar scenarios. Human behavior becomes unpredictable when it comes to making a decision in emergency situations. The cost and risk of determining these human behavior characteristics in emergency situations is very high. This paper presents an immersive collaborative virtual reality (VR) environment for performing virtual building evacuation drills and active shooter training scenarios using Oculus Rift head mounted displays. The collaborative immersive environment is implemented in Unity 3D and is based on run, hide, and fight mode for emergency response. The immersive collaborative VR environment also offers a unique method for training in emergencies for campus safety. The participant can enter the collaborative VR environment setup on the cloud and participate in the active shooter response training environment, which leads to considerable cost advantages over large-scale real-life exercises. A presence questionnaire in the user study was used to evaluate the effectiveness of our immersive training module. The results show that a majority of users agreed that their sense of presence was increased when using the immersive emergency

    In many complex tasks, a remote expert may need to assist a local user or to guide his or her actions in the local user's environment. Existing solutions also allow multiple users to collaborate remotely using high-end Augmented Reality (AR) and Virtual Reality (VR) head-mounted displays (HMD). In this paper, we propose a portable remote collaboration approach, with the integration of AR and VR devices, both running on mobile platforms, to tackle the challenges of existing approaches. The AR mobile platform processes the live video and measures the 3D geometry of the local environment of a local user. The 3D scene is then transited and rendered in the remote side on a mobile VR device, along with a simple and effective user interface, which allows a remote expert to easily manipulate the 3D scene on the VR platform and to guide the local user to complete tasks in the local environment.

    Immersive Analytics (IA) and consumer adoption of augmented reality (AR) and virtual reality (VR) head-mounted displays (HMDs) are both rapidly growing. When used in conjunction, stereoscopic IA environments can offer improved user understanding and engagement; however, it is unclear how the choice of stereoscopic display impacts user interactions within an IA environment. This paper presents a pilot study that examines the impact of stereoscopic display choice on object manipulation and environmental navigation using consumeravailable AR and VR HMDs. Our observations indicate that the display can impact how users manipulate virtual content and how they navigate the environment.
