Guided Exploration in Virtual Environments

by Steffi Beckhaus, Gerhard Eckel, Thomas Strothotte , 2001
"... We describe an application supporting alternating interaction and animation for the purpose of exploration in a surround-screen projection-based virtual reality system. The exploration of an environment is a highly interactive and dynamic process in which the presentation of objects of interest can ..."

Touching floating objects in projection-based virtual reality environments

by D. Valkov, F. Steinicke, G. Bruder, K. Hinrichs, J. Schöning, F. Daiber, A. Krüger - In Joint Virtual Reality Conference of EuroVR - EGVE - VEC , 2010
"... Touch-sensitive screens enable natural interaction without any instrumentation and support tangible feedback on the touch surface. In particular multi-touch interaction has proven its usability for 2D tasks, but the challenges to exploit these technologies in virtual reality (VR) setups have rarely ..."

Quality Evaluation of Projection-Based VR Displays

by Dave Pape, Dan Sandin , 2000
"... We present a collection of heuristics and simple tests for evaluating the quality of a projection-based virtual reality display. A typical VR system includes numerous potential sources of error. By understanding the characteristics of a correctly working system, and the types of errors that are ..."

Projection-Based Augmented Reality Distributed Systems Seminar FS2013

by Alexander Cebulla
"... In this seminar report a branch of augmented reality (AR), namely, projection-based augmented reality (projected AR) is discussed. To do so four different projected AR systems are presented: Virtual Showcase, iLamp, RoomProjector and SLAMProjector. By a comparison between projected AR and hand-held ..."

Abstract Collaborative Interaction Concepts for City Planning Tasks in Projection-Based Virtual Reality Systems

by unknown authors
"... In this paper we propose solutions that allow several co-located city planners to perform domain-specific interaction tasks together in one semi-immersive projection-based VR system. After a registration process, e.g., by posing gestures or by using speech commands, this group activity can be perfor ..."

Line of Sight Method for Tracker Calibration in Projection-Based VR Systems

by Marek Czernuszenko, Daniel Sandin, Daniel S, Thomas Defanti - Proc. 2nd International Immersive Projection Technology Workshop , 1998
"... This paper describes a method for correcting static errors in the position component of a 6-degree-offreedom tracker in a projection-based VR system. This method allows users to observe where errors in the environment are significant and correct them interactively. Later touch-up correction is possi ..."

is possible as well. This technique is based on superimposing targets in physical space with their virtual images. The only hardware addition to the VR system required is a few precisely placed targets. Keywords: Tracker calibration, Virtual Reality, Projection-Based VR, CAVE, ImmersaDesk. 1 Introduction 1

The Studierstube Augmented Reality Project

by Dieter Schmalstieg, Anton Fuhrmann, Gerd Hesina, Zsolt Szalavári, L. Miguel Encarnação, Michael Gervautz, Werner Purgathofer , 2000
"... Our starting point for developing the Studierstube system was the belief that augmented reality, the less obtrusive cousin of virtual reality, has a better chance of becoming a viable user interface for applications requiring manipulation of complex three-dimensiona information as a daily routine. I ..."

Balance NAVE; A Virtual Reality Facility for Research

by And Rehabilitation Of, Jeffrey Jacobson, Mark S. Redfern, Joseph M Furman - In Proceedings of the ACM Symposium on Virtual Reality Software and Technology 2001 , 2001
"... We are currently developing an immersive virtual environment display for research into the rehabilitation of balance disorders, called the Balance NAVE (BNAVE). Using this system, the therapist can create varying degrees of sensory conflict and congruence in persons with balance disorders. With the ..."

. With the capability of changing visual scenes based on the needs of the therapist, the BNAVE is a promising tool for rehabilitation. The system uses four PC's, three stereoscopic projectors, and three rear-projected screens, which surround the patient's entire horizontal field of view. The BNAVE can

Calibration-free augmented reality

by Kiriakos N. Kutulakos, James R. Vallino, Student Member - IEEE Transactions on Visualization and Computer Graphics , 1998
"... Abstract—Camera calibration and the acquisition of Euclidean 3D measurements have so far been considered necessary requirements for overlaying three-dimensional graphical objects with live video. In this article, we describe a new approach to videobased augmented reality that avoids both requirement ..."
