Affect recognition during active game playing based on posture skeleton data
(2013)The affective state of a player during game playing has a significant effect on the player's motivation and engagement. Recognising player's emotions during games can help game designers improve the user experience by ...

A case study of a virtual audience in a reconstruction of an ancient Roman odeon in Aphrodisias
(Association for Computing Machinery, Inc, 2005)The benefits of including virtual humans into cultural heritage reconstructions are twofold: the realism of architectural models is increased by populating them

The CREATE project: Mixed reality for design, education, and cultural heritage with a constructivist approach
(Institute of Electrical and Electronics Engineers Inc., 2003)The global scope of the CREATE project is to develop a mixed-reality framework that enables highly interactive real-time construction and manipulation of photo-realistic, virtual worlds based on real data sources. This ...

Employing virtual worlds for HCI education: A problem-based learning approach
(2012)In this paper we describe our experience focused on teaching an introductory course in HCI by employing a 3D virtual world. Our main pedagogical philosophy is presented which claims that problem-based learning activities ...

Fitting behaviors to pedestrian simulations
(2009)In this paper we present a data-driven approach for fitting behaviors to simulated pedestrian crowds. Our method annotates agent trajectories, generated by any crowd simulator, with action-tags. The aggregate effect of ...

Image-based crowd rendering
(2002)Rendering crowded scenes with thousands of different animated virtual people in real time is challenging. An image-based rendering approach for displaying multiple avatars is proposed. The system allows real-time rendering ...

Motion indexing of different emotional states using LMA components
(2013)Recently, there has been an increasing use of pre-recorded motion capture data, making motion indexing and classification essential for animating virtual characters and synthesising different actions. In this paper, we use ...

A selective approach for tone mapping High Dynamic Range content
(2011)Large resolution High Dynamic Range (HDR) textures/images are becoming common in computer graphics applications. However, it is still a prohibitive task to perform on them a filtering step such as tone mapping in real-time. ...

A survey of visibility for walkthrough applications
(2003)Visibility algorithms for walkthrough and related applications have grown into a significant area, spurred by the growth in the complexity of models and the need for highly interactive ways of navigating them. In this ...

View volume culling using a probabilistic caching scheme
(ACM, 1997)This paper a new algorithm for view volume culling. During an interactive walkthrough of a 3D scene, at any moment a large proportion of objects will be outside of the view volume. Frame-to-frame coherence implies that the ...

Viewspace partitioning of densely occluded scenes
(ACM, 1998)Computing the visibility of out-door scenes is often much harder than of in-door scenes. The difficulty is that although the majority of objects are hidden, some parts might be visible at a distance in an arbitrary location, ...

Visualizing crowds in real-time
(2002)Real-time crowd visualization has recently attracted quite an interest from the graphics community and, as interactive applications become even more complex, there is a natural demand for new and unexplored application ...
