An acute confusional state was observed to follow heavy exposure to polyurethane gloss paint fumes in a previously healthy 60 year old man. This state remitted over a 3-day period, but was followed by transient bone marrow suppression and evidence of liver cell damage. The corroborated absence of other toxins and the temporal association of exposure to paint fumes suggest that a volatile paint ...

This paper introduces GAVIP, an interactive and immersive platform allowing for audio-visual virtual objects to be controlled in real-time by physical gestures and with a high degree of intermodal coherency. The focus is particularly put on two scenarios exploring the interaction between a user and the audio, visual, and spatial synthesis of a virtual world. This platform can be seen as an exte...

In this paper, the perceptually based loss functions for audio filtering used by Wolfe and Godsill [1] are shown to fit well within a complex-valued Support Vector Machine (SVM) framework. SVM regression is extended to estimation of complex-valued functions, including the derivation of a variant of the Sequential Minimal Optimisation (SMO) algorithm. Audio filters are derived using this based o...

Spatialized soundtracks and sound-effects are standard elements of today’s video games. However, although 3D audio modeling and content creation tools (e.g., Creative Lab’s EAGLE [4]) provide some help to game audio designers, the number of available 3D audio hardware channels remains limited, usually ranging from 16 to 64 in the best case. While one can wonder whether more hardware channels ar...

Abstract Gloss is one of the main attributes to describe appearance surfaces and objects, as it contributes general quality perception. a multidimensional quantity which ‘specular gloss’ most commonly applied attribute. Specular gloss meters are standardized widely used in industry. However, their readings correlate only partially visual impression, also comprises distinctness-of-the-reflected-...

The SMART-I2 aims at creating a precise and coherent virtual environment by providing users with both audio and visual accurate localization cues. Wave field synthesis, for audio rendering, and tracked passive stereoscopy, for visual rendering, individually permit high quality spatial immersion within an extended space. The proposed system combines these two rendering approaches through the use...
