Cooperative Object Manipulation in Immersive Virtual Environments

Joint Manipulation Management in Collaborative Virtual Environments

Some international standards have been developed that are very likely to make a major impact on CVE (Collaborative Virtual Environment) technology: the Distributed Interactive Simulation (DIS) (IEEE Standard 1278.1)[8] and the High Level Architecture (HLA) (IEEE Standard 1516) [1]. Deriving from military-purpose simulations, DIS and HLA, however, have limitations on building large-scale general...

Efficient Manipulation of Object Groups in Virtual Environments

In this paper, we describe simple techniques for object group manipulation, an important operation in user interaction with a Virtual Environment. All presented manipulation techniques exploit constraints to simplify user interaction. The techniques are based on how humans perceive groups and afford direct manipulation of such groups. Furthermore, we introduce two new intuitive ways to create a...

Cooperative elastic object manipulation performed by virtual joystick operation

This paper presents a virtual manipulation environment dealing with elastic objects. An original fast computation elastic model ‘the gradational resolution model’ is introduced for real-time interaction, in which the number of elastic elements are efficiently reduced for acceleration. Joystick force feedback is used for sensible interaction. Two kinds of collision algorithms are examined by joy...

Collaborative Virtual Reality Environments

The development of Collaborative Virtual Reality Environment (CVRE) for education is a challenging process. One of the many challenges faced during the development of CVRE is the creation, transfer and delivery of educational multimedia content. This multimedia content could include images, voice, video and their combination. The overall goal of this project was to develop a fully integrated sy...
