A framework for immersive VR and full-body avatar interaction

Abstract

We present a new software framework for the development of immersive collaborative virtual reality applications with emphasis on full-body interaction with virtual humans. The framework is designed to be scalable and adaptable to different hardware configurations, using either commodity or more expensive hardware setups. High level programming abstractions handle object replication and communication channels for configurations based on multiple rendering nodes. The system provides tools for full-body character animation, real-time full-body tracking and retargeting to virtual humans, including motion reconstruction from a small set of sensors. Such capabilities allow new full-body interaction metaphors to be developed in fixed or user-perspective stereo visualization. The framework is scalable, customizable, cross-platform and it is only based on tools with source code available.

3D Printing and Immersive Visualization for Improved Perception of Ancient Artifacts

“…Tactile augmentation is considered an effective alternative mixed-reality technique for introducing tactile cues (Follmer, Leithinger, Olwal, Hogge, & Ishii, 2013, 417-426;Pureform, 2013;inFORM, 2013;Jansson et al, 2003;Jeonghun et al, 2003;Hoffman, 1998). This technique is very effective with dedicated hardware appliances in dedicated exhibit spaces such as CAVE environments, dark rooms, and virtual theaters (Kenderdine, Forte, & Camporesi, 2012;Camporesi & Kallmann, 2013;Forte, 2008;Carrozzino & Bergamasco, 2010). Economic resources and multidisciplinary collaborations are, however, not always available in order to create and maintain such complex dedicated hardware.…”

Framing the past: How virtual experience affects bodily description of artefacts

“…Future studies might include other media, such as 3D immersive systems (Powerwall and CAVE), haptic interface and force feedback. Three-dimensional immersive systems are stereoscopic interactive visualization systems used to visualize the 3D models, which use camera (or similar) tracking of visitor's movements to create interactive relationships between the visitor and the reconstructed/simulated environment [37,38]. Haptic interface and force feedback are able to reproduce the feel of physical contact with objects and the perception of tactile stimuli [17,[39][40][41].…”

Modular Digital Exposition and Education Platform: Concept and Its Implementation into the Educational Process of Archaeology Based on Novosibirsk State University

“…Цифровые технологии все сильнее проникают в сферу сохранения культурного наследия, позволяют хранить и воспроизводить большие объемы данных, изображений, видео-и звуковых файлов . Последние разработки в области цифровых технологий привели к появлению новых способов визуализации и виртуального экспонирования , а также к созданию экспозиций с эффектом погружения, с использованием, например, датчиков захвата движения [Camporesi, Kallmann, 2013]. Это позволяет поместить физический объект в виртуально расширенное, дополненное пространство в сочетании с предметным экспонированием.…”
