Large consumer suppliers, such as automotive manufacturers and retail companies, are beginning to implement augmented reality as part of their advertising strategy. Augmented reality (AR) is defined as the integration of digitally created media within an existing actual environment. This combination of virtual three-dimensional images within tangible surroundings provides unique sensory capabil...

ARToolKit programmers are familiar with the kanji symbols supplied with the distribution. Most of them have do not know what these kanji symbols mean. We propose a piece of educational software that uses collaborative Augmented Reality (AR) to teach users the meaning of kanji symbols. The application is laid out as a two player Augmented Reality computer game. The novelty of our approach is tha...

As computers increase in power and decrease in size, new mobile, wearable, and pervasive computing applications are rapidly becoming feasible, providing people access to online resources always and everywhere. This new flexibility makes possible new kind of applications that exploit the person's surrounding context. Augmented reality (AR) presents a particularly powerful user interface (UI) to ...

Augmented Reality (AR) aims at developing new user interfaces. Although research has produced a large number of application prototypes and AR frameworks in the last 20 years, no project has yet been practical enough to create a mass market success. There are many reasons for this. Traditionally, AR researchers have primarily created prototypes that aim to solve engineering problems such as main...

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 video-based augmented reality that avoids both requirements: it does not use any metric information about the calibration parameters of the camera or the 3D locatio...

Virtual environments of the Digital Earth were from its beginning quickly enriched by usage of the augmented reality. The following paper is focused on possibilities to include strictly cartographic methods of visual representation of data into the Digital Earth representation. The idea is to embed cartographically processed and visualized thematic information into the augmented reality without...

5 Definition and motivation Increasing realism in today’s Virtual Reality (VR) applications often requires months of human work, spent with modeling objects with realistic apperance and behavior. It also requires the purchase of highend graphics workstations that are able to perform the computing in real-time. In many cases, however, a complete immersion of the user into a synthetic environment...

Motivation: A student in a math, science, or engineering class will undoubtedly come across an equation in the course of his or her studies that the student will want to quickly visualize. Plotting the equation allows the student to better understand some property of the real variables the equation relates. However, this may still be difficult for younger students that are working on building t...

In this paper we present Studierstube Workspace, an application framework for augmented reality. We develop a concept for a collaborative working environments that simultaneously supports multiple users as well as multiple applications and in particular multi-tasking. The co-presence of multiple users interacting with multiple concurrently executing applications opens up new possibilities in th...
