Making VR work

Abstract

Building a real-world immersive 3D modeling application is hard. In spite of the many supposed advantages of working in the virtual world, users quickly tire of waving their arms about and the resulting models remain simplistic at best. The dream of creation at the speed of thought has largely remained unfulfilled due to numerous factors such as the lack of suitable menu and system controls, inability to perform precise manipulations, lack of numeric input, challenges with ergonomics, and difficulties with maintaining user focus and preserving immersion. The focus of our research is on the building of virtual world applications that can go beyond the demo and can be used to do real-world work. The goal is to develop interaction techniques that support the richness and complexity required to build complex 3D models, yet minimize expenditure of user energy and maximize user comfort. We present an approach that combines the natural and intuitive power of VR interaction, the precision and control of 2D touch surfaces, and the richness of a commercial modeling package. We also discuss the benefits of collocating 2D touch with 3D bimanual spatial input, the challenges in designing a custom controller targeted at achieving the same, and the new avenues that this collocation creates.

Enhancing Biology Laboratory Learning: Student Perceptions of Performing Heart Dissection With Virtual Reality

“…The whole laboratory environment is illustrated in Figure 1. By incorporating the complete laboratory setting, we aim to simulate a realistic and immersive learning environment, enhancing the overall educational experience [29]. Additionally, the inclusion of the entire laboratory environment allows for a comprehensive analysis of how VR technology can be seamlessly integrated into traditional educational settings, offering insights into its potential impact on students' engagement and learning outcomes [30].…”

How Visual Motion Cues Can Influence Sickness For In-Car VR

“…viewing content which requires constant and rapid changes in gaze orientation, compared to content which is stable or whose orientation or position is physically manipulated by the user (e.g. reading a book, or physically grabbing and moving the world [47]). Thus, careful consideration must be given as to what particular form of motion conflict is examined, and how it is physically enacted.…”

MobiSweep

“…Mobile devices offer a unique combination of computational power, wireless data communication, 3D sensing capabilities, ergonomic manipulability, and multi-touch input mechanisms. Although mobile devices have been previously explored as spatial controllers for several virtual applications [2,22], inertial position tracking is impractical without adding additional hardware [17]. Here, the multi-touch capability of phones and tablets provides additional affordances for both direct and indirect manipulations of the virtual objects.…”

“…However, their work was more focused on demonstrating general interactions for modeling scenarios rather than exploring a concrete design work-flow for shape composition. Mine et al [17] described and discussed an immersive adaptation of the SketchUp application using a tracked smartphone in a CAVE setting. Our work differs from these works in two ways: (a) our intention is to support quick creative compositions with actual 3D surfaces in contrast to [29,28,15] and (b) our system does not use any additional hardware or vision based method for explicit position tracking (such as in [27,14,17]).…”
