Consumer-grade head-mounted displays (HMD) such as the Oculus Rift have become increasingly available for Virtual Reality recently. Their high degree of immersion and presence provokes usually amazement when first used. Nevertheless, HMDs also have been reported to cause adverse reactions such as simulator sickness. As their impact is growing, it is(More)
We present work in progress on an intelligent embodied conversation agent in the basic care and healthcare domain. In contrast to most of the existing agents, the presented agent is aimed to have linguistic cultural, social and emotional competence needed to interact with elderly and migrants. It is composed of an ontology-based and reasoning-driven(More)
In this paper the Inertial Measurement Unit (IMU) included inside the Oculus Rift virtual reality headset is considered for head position tracking. While the Oculus is capable of mapping rotational movement to a virtual scene, recovering translational movement is not possible by default. In this study, we extract position data using a different approach for(More)
In this paper we present the methods and techniques used to visualize the trajectory of the participants of a massive virtual regatta using a virtual globe in the web browser. The emergence of new web technologies, such as HTML5 and WebGL, have opened new avenues for visualizing and sharing 3D data. However, web-based visualization of big data is still(More)
Virtual characters are an integral part of many games and virtual worlds. The ability to accurately synchronize lip movement to audio speech is an important aspect in the believability of the character. In this paper we propose a simple rule-based lip-syncing algorithm for virtual agents using the web browser. It works in real-time with live input, unlike(More)
