The proposed multiple-point interaction technique realizes direct interaction and control in a virtual environment and presentation. The device for interaction is constructed on the basis of the infrared (IR) laser which is invisible for a human eye and does not interfere with the visual channel of a presentation, since there can be no coincidence of the(More)
This paper describes tools and techniques for the exploration of geo-scientific data from the oil and gas domain in stereoscopic virtual environments. The two main sources of data in the exploration task are seismic volumes and multivariate well logs of physical properties down a bore hole. We have developed a props-based interaction device called the cubic(More)
We present a framework for the design and evaluation of distributed, collaborative 3D interaction focussing on projection based systems. We discuss the issues of collaborative 3D interaction using audio/video for face-to-face communication and the differences in using rear projection based Virtual Environments. Further, we explore how the use of(More)
Simulation of an object's elastic deformation is an important feature in applications where three-dimensional object behavior is explored. In addition, the benefits of user-object interactions are best realized in interactive environments which require the rapid computation of deformations. In this paper we present a prototype of a system for the simulation(More)
