In this exploratory article, we ask how states come to be understood as entities with particular spatial characteristics, and how changing relations between practices of government and national territories may be challenging long-established modes of state spatiality. In the first part of this article, we seek to identify two principles that are key to state spatialization: vertically (thestate...

The full integration and synchronization of 3D sound and image requires a data model and an architecture that allow for homogeneous description of geometrical and sonic components, together with mechanisms for distributed and synchronized rendering. First, several modes of sound and graphic combination are examined, and the resulting constraints for the rendering tools are detailed. Virtual Cho...

The effect of spatial auditory information on a listener’s ability to detect, identify, and monitor multiple simultaneous speech signals was evaluated using virtual audio technology. Factorial combinations of three variables the number of localized speech signals, the location of the speech signals around the horizontal plane, and the sex of the talker were employed using a within-subjects desi...

Interactive environmental audio spatialization technology has become commonplace in personal computers and is migrating into portable entertainment platforms (including cell phones) and multiplayer game servers (virtual online worlds). While the primary current application of this technology is 3D game sound track rendering, it is ultimately necessary in the implementation of any personal or sh...

In the last few years, Linked Open Data sources have extremely increased in number. Despite their enormous potential, it is really hard to find effective and efficient ways for navigating and exploring them, mainly because of complexity and volume issues. In fact, application developers, students and researchers that are not experts in Semantic Web technologies often lose themselves in the intr...

Though the use of the Fast Fourier Transform (FFT) for signal processing in music applications has been widespread, applications in real-time systems for dynamic spectral transformation has been quite limited. The limitations have been largely due to amount of computation required for the operations. With faster machines, and with suitable implementations for frequency-domain processing, real-t...

We investigate the relationship of perceived distances to judged similarities between document points in various types of spatialized displays. Our findings suggest that the distance–similarity relationship is not as self-evident to viewers as is commonly assumed in the information visualization literature. We further investigate how participants interpret instructions to judge distances when t...

This paper proposes a novel scheme for acoustic echo cancellation (AEC) in multi-party, spatialized audio conferencing by exploring the constraints among the adaptive filters for each synthesized remote speaker. The AEC algorithm employs constrained Kalman filtering (CKF-AEC) that takes advantage of the uncorrelated reference signal from each remote channel [1], yet restricts the filter adaptat...

The idea for a sound installation in an art gallery began as a collaboration which aimed to integrate ideas of sound spatialization and the manipulation of spatial perception from an architectural point of view. The challenge was to apply and test concepts common both to space and sound in a way that would fit a selected location. The location chosen for this purpose was Galerie PI, located in ...

Location-based games introduce an element that is missing in interactive console games: movements of players involving locomotion and thereby the physical effort characteristic of any sportive activity. The paper explores how to design location-based games combining locomotion with strategic reasoning by using classical board games as templates. It is shown that the straightforward approach to ...
