Efficient 3D Pointing Selection in Cluttered Virtual Environments [PDF]
IEEE Computer Graphics and Applications, 2009 Most pointing techniques for 3D selection on spatially-immersive virtual environments rely on a ray originating at the user's hand whose direction is controlled by the hand orientation. In this paper we study the potential mismatch between visible objects (those which appear unoccluded from the user's eye position) and se-lectable objects (those which ...

Using 3D Sound for Providing 3D Interaction in Virtual Environment [PDF]
ASME 2010 World Conference on Innovative Virtual Reality, 2010 In this paper we describe a proposal based on the use of 3D sound metaphors for providing precise spatial cueing in virtual environment. A 3D sound metaphor is a combination of the audio spatialization and audio cueing techniques. The 3D sound metaphors are supposed to improve the user performance and perception.

Applying constrained virtual environments to serious games for heritage
International Journal of Serious Games, 2019 Virtual environments are an important aspect of serious games for heritage. However navigable three-dimensional (3D) environments can be costly and resource-intensive to create and for users to run. In this paper, we propose an alternative approach using
