This paper deals with the question how the component idea can be transferred to the authoring of 3D content for the WWW. The concept of 3D Beans and their according authoring environment is presented. In addition, an implementation of this concept using Java3D and Java Beans is described. Advantages of the concept are discussed and illustrated with an… (More)
Multimodal interaction provides the user with multiple modes of interacting with a system, such as gestures, speech, text, video, audio, etc. A multimodal system allows for several distinct means for input and output of data. In this paper, we present our work in the context of the I-SEARCH project, which aims at enabling context-aware querying of a… (More)
A vital requirement for a successful software framework for digital storytelling is that it takes the abilities and background of the story authors into account. Dedicated tools should support authors in expressing their stories within this framework at an adequate level and point out an according authoring process for digital stories. The software… (More)
A system for communication and decision training in emergency situations is presented that uses autonomous agents for simulating and explaining human behavior. Trainees and agents act together in a shared virtual environment that is distributed via computer network. It is shown how an agent can autonomously control its visual appearance in 2D graphical user… (More)
In this paper, we report on work around the I-SEARCH EU (FP7 ICT STREP) project whose objective is the development of a multimodal search engine. We present the project's objectives, and detail the achieved results, amongst which a Rich Unified Content Description format.
kARbon demonstrates a web-based mixed reality (MR) support and collaboration tool for a wide range of construction planning and supervising scenarios. We describe how the construction process can be supported for locally distributed workers, experts and decision makers by leveraging MR methods in combination with effective and pure web-based collaboration,… (More)
We present an adaptive bandwidth-optimized approach for progressive image transmission to allow instant textured rendering in web-based 3D applications. Applications utilizing a lot of image data require an adaptive technology to build responsive user interfaces. This applies especially for the use in mobile networks. While several approaches provide a… (More)
