In four-sided CAVE-like VR systems, the absence of the rear wall has been shown to decrease the level of immersion and can introduce breaks in presence. In this paper it is investigated to which extent user’s attention can be driven by visual and auditory stimuli in a four-sided CAVE-like system. An experiment was conducted in order to analyze how user attention is diverted while physically walking...
This paper presents an immersive application where users receive sound and visual feedbacks on their interactions with a virtual environment. In this application, the users play the part of conductors of an orchestra of factory machines since each of their actions on interaction devices triggers a pair of visual and audio responses. Audio stimuli were spatialized around the listener. The application...
Modal sound synthesis is a useful method to interactively generate sounds for Virtual Environments. Forces acting on objects excite modes, which then have to be accumulated to generate the output sound. Due to the high audio sampling rate, algorithms using the CPU typically can handle only a few actively sounding objects. Additionally, force excitation should be applied at a high sampling rate. We...
Immersive Virtual Musical Instruments (IVMIs) can be considered as the meeting between Music Technology and Virtual Reality. Being both musical instruments and elements of Virtual Environments, IVMIs require a transversal approach from their designers, in particular when the final aim is to play them in front of an audience, as part of a scenography. In this paper, we combine the main constraints...
While the design of computational audio models for real-time generation of sound has been gaining increasing attention in the field of virtual reality and games over the last few years, questions related to expressivity and human performability have remained largely unexplored. Unlike in the design of interactive sonic artefacts a performable model requires a different approach to parametrisation...
Digital sounds can be processed such that auditory cues are created that convey spatial location within a virtual auditory environment (VAE). Only in recent years has technology advanced such that au- dio can be processed in real-time as a user navigates an environ- ment. We must first consider the perceptual challenges faced by 3D sound rendering, before we can realize its full potential. Now more...
The use of sonification for navigation, localization and obstacle avoidance is considered to be one of the most important tasks in auditory display research for its potential application to navigation systems in vehicles and smartphones, assistive technology and other eyes-free applications. The aim of this technology is to deliver location-based information to support navigation through sound. In...
Realistic sound effects are extremely important in VR to improve the sense of presence and immersion. They augment the visual sense of the user and can help reduce simulation fatigue. Sound can provide 3D spatial cues outside eld of view and help create high-fidelity VR training simulations. Current sound propagation techniques are based on heuristic approaches or simple line-of-sight based geometric...
