Scientific Visualization in Collaborative Virtual Environment with PDA-Based Control and 3D Annotation

Abstract

Scientific collaborative visualization based on visual data mining is an efficient approach for facilitating the intellectual discovery and understanding the visualization data obtained from large-scale ata sets. We think that Collaborative Virtual Environment (CVE) is one of the efficient method to achieve collaborative works by sharing a virtual reality 3D space among users at remote places. In addition, it would be more useful if we could use virtual 3D annotations during collaborative work. In this paper, therefore, we construct a HybridP2P-based CVE in which a wireless handheld PDA is used for making 3D annotations and changing some visualization parameters when necessary.

The State of the Art of Spatial Interfaces for 3D Visualization

“…For example, Kukimoto et al. [KNEK05] use a tracked PDA in a collaborative VR environment to capture annotations. A single button press activates the note taking that is done by moving the PDA in the 3D space.…”

“…Interestingly, Kukimoto et al. [KNEK05] proposed to use a tracked PDA to take notes in a VR environment by using it solely as a tangible note‐taking device or combining its location with the pen input. Finally, Lubos et al.…”

Tele-immersive environment with tiled display wall for intuitive remote collaborative work

“…Recently, Immersive Projection Technology (IPT) such as the CAVE system has become popular, and teleimmersive virtual environments have been constructed by several IPT environments [4]. Video avatar technology has been studied to realize real-world-oriented 3D human images for remote communication with high-presence tools between remote places [5].…”

Design and implementation for a bimanual input system on virtual environments

“…Kukimoto et al proposes an input system using a PDA (Personal Digital Assistant) in IPT systems [4]. The PDA communicates with the IPT system via the network.…”
