The objective of the Project MANEUVER (Manufacturing Education Using Virtual Environment Resources)1 is to develop an affordable virtual reality (VR) framework to address the imminent demand for well-trained digital manufacturing (DM) professionals. One important part of Project MANEUVER involves studying, evaluating, and identifying cost-efficient ways to generate 3D solid models for use in VR frameworks. To this end, this paper explains the research effort to find alternative ways so that 3D solid model could easily be generated without using any costly 3D scanning technology. In this study, the project team identified two software tools that could help the manufacturing professionals and educators generate a solid model of several parts. These two software tools namely, Qlone and 3DF Zephyr Free were selected for this study based on factors such as ease-of-use, cost-effectiveness, and the cognitive load on users. Using case-studies these two software tools were used to generate 3D solid models and prototypes. Finally, their pros and cons collected throughout this study were reported.

An Artists' Perspectives on Natural Interactions for Virtual Reality 3D Sketching
Virtual Reality (VR) applications like OpenBrush offer artists access to 3D sketching tools within the digital 3D virtual space. These 3D sketching tools allow users to “paint” using virtual digital strokes that emulate real-world mark-making. Yet, users paint these strokes through (unimodal) VR controllers. Given that sketching in VR is a relatively nascent field, this paper investigates ways to expand our understanding of sketching in virtual space, taking full advantage of what an immersive digital canvas offers. Through a study conducted with the participation of artists, we identify potential methods for natural multimodal and unimodal interaction techniques in 3D sketching. These methods demonstrate ways to incrementally improve existing interaction techniques and incorporate artistic feedback into the design.

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

null (Ed.)Though virtual reality (VR) has been advanced to certain levels of maturity in recent years, the general public, especially the population of the blind and visually impaired (BVI), still cannot enjoy the benefit provided by VR. Current VR accessibility applications have been developed either on expensive head-mounted displays or with extra accessories and mechanisms, which are either not accessible or inconvenient for BVI individuals. In this paper, we present a mobile VR app that enables BVI users to access a virtual environment on an iPhone in order to build their skills of perception and recognition of the virtual environment and the virtual objects in the environment. The app uses the iPhone on a selfie stick to simulate a long cane in VR, and applies Augmented Reality (AR) techniques to track the iPhone’s real-time poses in an empty space of the real world, which is then synchronized to the long cane in the VR environment. Due to the use of mixed reality (the integration of VR & AR), we call it the Mixed Reality cane (MR Cane), which provides BVI users auditory and vibrotactile feedback whenever the virtual cane comes in contact with objects in VR. Thus, the MR Cane allows BVI individuals to interact with the virtual objects and identify approximate sizes and locations of the objects in the virtual environment. We performed preliminary user studies with blind-folded participants to investigate the effectiveness of the proposed mobile approach and the results indicate that the proposed MR Cane could be effective to help BVI individuals in understanding the interaction with virtual objects and exploring 3D virtual environments. The MR Cane concept can be extended to new applications of navigation, training and entertainment for BVI individuals without more significant efforts.more » « less

Augmented/Virtual reality and video-based media play a vital role in the digital learning revolution to train novices in spatial tasks. However, creating content for these different media requires expertise in several fields. We present EditAR, a unified authoring, and editing environment to create content for AR, VR, and video based on a single demonstration. EditAR captures the user’s interaction within an environment and creates a digital twin, enabling users without programming backgrounds to develop content. We conducted formative interviews with both subject and media experts to design the system. The prototype was developed and reviewed by experts. We also performed a user study comparing traditional video creation with 2D video creation from 3D recordings, via a 3D editor, which uses freehand interaction for in-headset editing. Users took 5 times less time to record instructions and preferred EditAR, along with giving significantly higher usability scores.more » « less

This is one of the first accounts for the security analysis of consumer immersive Virtual Reality (VR) systems. This work breaks new ground, coins new terms, and constructs proof of concept implementations of attacks related to immersive VR. Our work used the two most widely adopted immersive VR systems, the HTC Vive, and the Oculus Rift. More specifically, we were able to create attacks that can potentially disorient users, turn their Head Mounted Display (HMD) camera on without their knowledge, overlay images in their field of vision, and modify VR environmental factors that force them into hitting physical objects and walls. Finally, we illustrate through a human participant deception study the success of being able to exploit VR systems to control immersed users and move them to a location in physical space without their knowledge. We term this the Human Joystick Attack. We conclude our work with future research directions and ways to enhance the security of these systems.more » « less
