We present an approach to procedural generation of `pseudo infinite' virtual cities in real-time. The cities contain geometrically varied buildings that are generated as needed. The building generation parameters are created by a pseudo random number generator, seeded with an integer derived from the building's position. The varied building geometries are(More)
With the rise of Gamification, the boundaries between play and games on the one hand, and everyday life on the other are being challenged, and as a result game play is entering the realm of everyday life. We believe that with the breakdown of this dichotomy and with the increasing presence of game elements in everyday life in the form of Gamification, there(More)
We present the use of commodity depth based cameras to control viewpoint from passive unencumbered head tracking. This allowed participants to maintain correct perspective while playing an immersive computer ball game, without the need to wear devices, wires or markers. While viewpoint update is more generally useful than stereoscopy it has traditionally(More)
We introduce SpaceWalk, an experimental approach to allow a person to move around a small room while wearing a Head Mounted Display. The goal is to get immersed users in everyday settings out of their seats and naturally experiencing movement within the simulation. SpaceWalk integrates a wireless solution around commodity equipment and requires no(More)
With advances in computer hardware, 3D game worlds are becoming larger and more complex. Consequently the development of game worlds becomes increasingly time and resource intensive. This paper presents a framework for generation of entire virtual worlds using procedural generation. The approach is demonstrated with the example of a virtual city.
A 74-year-old male with atherosclerosis presented with severe nontyphoidal salmonellosis, and received outpatient therapeutic antimicrobial treatment. Nevertheless, within seven days he developed a mycotic aortic aneurysm, a serious but treatable complication. Its surgical management was successful. Rapid formation of mycotic aortic aneurysm represents a(More)
Autonomous cars are on the horizon, meaning passengers will no longer have to focus on driving leaving them with extra time for other activities, or engagements. However, research has focused primarily on safety related aspects of autonomous driving, overlooking the need to design for this new free time. This raises the question, <i>how do we design new(More)
Millions of people consider their car-based commuting a daily hassle. Autonomous car technology promises a relief from driving related stress and may change the commuting experience fundamentally. So far, research in this field has mainly been focused on commuting in manually driven cars or on usability and safety issues of specific driver automation(More)
3D modelling and animation software presents artists with unique creative opportunities and limitations that are dependent on design decisions implicit in the software's architecture, interface and workflow. This paper presents preliminary outcomes of a research project which explores these opportunities and limitations in order to develop new ways of(More)
