Producing ultra-high-quality content is the next grand challenge for the VR industry. Creating a virtual reality that even the human eye cannot distinguish from the real world will require light-field technology--3D imaging technology that captures the light rays people perceive from different locations and directions. When combined with computer vision and machine learning, light-field technology...
Cutting-edge work on 3D telepresence at a multinational research center provides insight into the technology's potential, as well as into its remaining challenges. The first Web extra at http://youtu.be/r4SqJdXkOjQ is a video describing FreeCam, a system capable of generating live free-viewpoint video by simulating the output of a virtual camera moving through a dynamic scene. The second Web extra...
As an important research field in image based rendering, relighting techniques make it possible to synthesis physically real objects in virtue scenes, which will definitely enhance sense of reality for users and thus improve user experience. On the other hand, as an important branch of augment reality, spatially augmented reality also seeks for user experience enhancement in emersions, which is achieved...
In order to shorten the learning curve and simplify the complex in current CAD system, one direct approach is to provide a more intuitive way of interaction. This paper proposes an interactive pen tool, which transforms the actions in real space into the virtual three-dimensional CAD system space. Augmented Reality technology is used to track the operator's action in the real world. The design and...
An ongoing research problem in Augmented Reality (AR) is to improve tracking and display technology in order to minimize registration errors. However, perfect registration is not always necessary for users to understand the intent of an augmentation. This paper describes the results of an experiment to evaluate the effects of graphical context in a Lego block placement task when the graphics are located...
To achieve a realistic integration of virtual and real imagery in video see-through augmented reality, the rendered images should have a similar appearance and quality to those captured by the video camera. This paper describes a compositing method which models the artefacts produced by a small low-cost camera, and adds these effects to an ideal pinhole image produced by conventional rendering methods...
In 3D computer graphics, it has been an important issue to describe a virtual object realistically and show it in a physically correct manner. Unlike the virtual reality(VR), the augmented reality (AR) is an environment containing virtual and real objects simultaneously. However, the difference in motion between the virtual and real objects is obvious, which makes it hard for AR to be realistic and...
This paper presents an architecture to support fast prototyping of augmented reality systems, based on virtual reality. The architecture defines simulation services separated from other aspects of the system. These services support incremental evolution of simulated prototypes into nonsimulated systems. Focus is also placed on user interaction,through the definition of an interaction architecture...
A ubiquitous mixed reality system based on ldquoexperience contentsrdquo is presented. The 3D contents provided for users are associated with Korean ancient military weapons such as the turtle ship and the fire wagon, and overlaid on the real images captured by a UMPC camera while looking at the particular weapon displayed in the science museum. For an exact registration of the virtually modeled objects...
We have developed a browsing tool for visualizing information about geographic surfaces using map-based augmented reality (AR). Map-based AR technology enables virtual objects to be overlaid on an actual map, creating a tangible user interface. In map-based AR applications, a virtual lens pointer is often used for object selection. However, this type of interaction is difficult when there are many...
In this paper, we study how to exploit the context-awareness in augmented reality (AR) applications to take advantage of the context in both the high-level and low-level processing. We propose an AR system architecture that works with a context-awareness framework. In the system, both the preliminary and the final context is provided to the process that needs the context. We provide two scenarios...
This paper presents a method to reconstruct the surface reflectance of objects from images. For objects with spatially-varying materials, we assume that each point can be represented as a weighted sum of several basic materials. First, a cluster algorithm is applied to automatically compute the number of basic materials. Then, the weight map and parameters of the reflectance model are iteratively...
