Marker tracking and HMD calibration for a video-based augmented reality conferencing system

by Hirokazu Kato - in The 2nd International Workshop on Augmented Reality (IWAR 99 , 1999
"... We describe an augmented reality conferencing system which uses the overlay of virtual images on the real world. Remote collaborators are represented on Virtual Monitors which can be freely positioned about a user in space. Users can collaboratively view and interact with virtual objects using a sha ..."

Augmented Reality Through Wearable Computing

by Thad Starner, Steve Mann, Bradley Rhodes, Jeffrey Levine, Jennifer Healey, Dana Kirsch, Rosalind W. Picard, Alex Pentland , 1997
"... Wearable computing moves computation from the desktop to the user. We are forming a community of networked wearable computer users to explore, over a long period, the augmented realities that these systems can provide. By adapting its behavior to the user's changing environment, a body-worn com ..."

-worn computer can assist the user more intelligently, consistently, and continuously than a desktop system. A text-based augmented reality, the Remembrance Agent, is presented to illustrate this approach. Video cameras are used both to warp the visual input (mediated reality) and to sense the user's world

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 ..."

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 ..."

systems, one monitor-based and one head-mounted, demonstrate that the approach is readily implementable, imposes minimal computational and hardware requirements, and generates real-time and accurate video overlays even when the camera parameters vary dynamically. Index Terms—Augmented reality, real

CyberCode: Designing Augmented Reality Environments with Visual Tags

by Jun Rekimoto, Yuji Ayatsuka , 2000
"... The CyberCode is a visual tagging system based on a 2Dbarcode technology and provides several features not provided by other tagging systems. CyberCode tags can be recognized by the low-cost CMOS or CCD cameras found in more and more mobile devices, and it can also be used to determine the 3D positi ..."

This paper describes examples of augmented reality applications based on CyberCode, and discusses some key characteristics of tagging technologies that must be taken into account when designing augmented reality environments.

Exploring MARS: Developing Indoor and Outdoor User Interfaces to a Mobile Augmented Reality System

by Tobias Höllerer, Steven Feiner, Tachio Terauchi, Gus Rashid, Drexel Hallaway - Computers and Graphics , 1999
"... We describe an experimental mobile augmented reality system (MARS) testbed that employs different user interfaces to allow outdoor and indoor users to access and manage information that is spatially registered with the real world. Outdoor users can experience spatialized multimedia presentations tha ..."

Haptic collaboration with augmented reality

by Matt Adcock, Matthew Hutchins, Chris Gunn - SIGGRAPH 2004 Posters , 2004
"... We describe a (face-to-face) collaborative environment that provides a coherent mix of real world video, computer haptics, graphics and audio. This system is a test-bed for investigating new collaborative affordances and behaviours. 1. Collaborative Haptics and AR Our project goal is to develop a sy ..."

First steps towards handheld augmented reality

by Daniel Wagner, Dieter Schmalstieg , 2003
"... In this paper we describe the first stand-alone Augmented Reality (AR) system with self-tracking running on an unmodified personal digital assistant (PDA) with a commercial camera. The project exploits the ready availability of consumer devices with a minimal need for infrastructure. The application ..."

Registration Error Analysis for Augmented Reality

by Richard L. Holloway , 1997
"... Augmented reality (AR) systems typically use see-through head-mounted displays (STHMDs) to superimpose images of computer-generated objects onto the user's view of the real environment in order to augment it with additional information. The main failing of current AR systems is that the virtual ..."
