The design decisions are (1) the choice of the Scala programming language, (2) the implementation of the actor computational model, and (3) the central incorporation of ontologies as a base for semantic modeling, required for several Artificial Intelligence (AI) methods. A white-box expert review is applied to a detailed use case illustrating an interactive and multimodal game scenario, which requires a number of complex functional features like speech and gesture processing and instruction mapping. The review matches the three design decisions against three comprehensive non-functional requirements from software engineering: Reusability, scalability, and extensibility. The qualitative evaluation is condensed to a semi-quantitative summary, pointing out the benefits of the chosen technical design.","PeriodicalId":93673,"journal":{"name":"Proceedings of the ACM Symposium on Virtual Reality Software and Technology.

Within the design space, frontal and sidewise stances when using a flying surfboard interface were compared through a user study. The interfaces were adapted and improved from our previous designs using a body-mounted, multi-touch touchpad. Two different experiments were designed and conducted that focus on user performance and virtual world cognition, respectively. The results suggest better user performance and user experience when using the frontal stance, although no better spatial orientation or virtual world cognition was identified. Further, user interviews revealed that despite the realistic simulation of skateboarding/snowboarding, the sidewise stance suffers from poor usability due to inefficient and inaccurate turning control and confusion between the viewing and movement directions. Based on these results, several guidelines are proposed to aid the design of leaning-based travel interfaces for immersive virtual reality applications.","PeriodicalId":93673,"journal":{"name":"Proceedings of the ACM Symposium on Virtual Reality Software and Technology.

In this paper, we present a high-level VR middleware based on one of the most successful commercial game engines: the Unreal® Engine 3.0 (UE3). We describe a VR framework implemented as an extension to the Unreal® Development Kit (UDK) supporting CAVE\"-like installations. Our approach relies on a distributed architecture reinforced by specific replication patterns to synchronize the user's point of view and interactions within a multi-screen installation. Our performance benchmarks indicated that our immersive port does not affect the game engine performance, even with complex real-time applications, such as fast-paced multiplayer First Person Shooter (FPS) games or high-resolution graphical environments with 2M+ polygons. A user study also demonstrated the capacity of our VR middleware to elicit high spatial presence while maintaining low cybersickness effects. With free distribution, we believe such a platform can support future Entertainment and VR research.","PeriodicalId":93673,"journal":{"name":"Proceedings of the ACM Symposium on Virtual Reality Software and Technology.

In general modeling software, parts of such a complex 3D virtual objects are grouped and manipulated together, but not individually, for efficient operation. Therefore, a separating operation is necessary when the user wants to observe or manipulate only a part of a complex object. We have developed a system that realizes gesture-based separation and observation of a group of parts within complex virtual objects in 3D space. One of the practical applications of our system is in training, such as learning the structure of the human body or industrial products. In our system, users can separate a group of parts freely by pulling and cutting a virtual rubber band. The widths of these virtual rubber bands are relative to the connection strength between each part. This allows the user to easily understand relationships between parts. Additionally, this feedback provides a comfortable operational familiarity.","PeriodicalId":93673,"journal":{"name":"Proceedings of the ACM Symposium on Virtual Reality Software and Technology.
