TNA project : Surrounded by contacts : spatialization of multiple contact sounds in immersive space

Acronym : 113-Surrounded by contacts spatialization of multiple contact sounds in immersive space-Grani

Project Lead : Francesco Grani From : Aalborg University Copenhagen

Dates : from 7th July 2013 to 19th October 2013

Description :



Motivation and objectives :
The main objective of this research is to test the importance of spatialized audio in a VR walking experience, in a large space. Specifically, we will build an interactive audio-visual environment where the user walks around and is able to interact with different events by e.g. hitting with a foot. We will test the interaction with the environment in two conditions: one where the sound is rendered so the auditory feedback appears to happen where the action is (spatialized sound) and one without spatialization. We want to examine whether the condition with spatialized sound enhances the experience of interacting in the environment.

Teams :
The group from Aalborg University Copenhagen that will be part of the project is the Multimodal Interactive Experience (MIE) research cluster of the Department of Architecture, Design, and Media Technology. Multimodal Interactive Experience (MIE) is a research cluster that aims at exploring the combination of different input and output modalities in interactive applications. The cluster combines several competences on isolated sensory modalities available in the Architecture, Design and Media Technology department (sound technology, computer graphics and visualization, haptic technologies), as well as human computer interaction and interaction design research to investigate the combination among the different senses both in the real and the virtual world.

Recordings & Results :
The main objective of this research is to test the importance of spatialized audio in a VR walking experience, in a large space. Specifically, we will build an interactive audio-visual environment where the user walks around in presence of sounding objects. We will test the interaction with the environment in different conditions: one where the sound is rendered with binaural techniques, one where the binaural field is affected by a roto-translation, and another one in which the sound is rendered with stereo technique. We will then test the degree of immersion that the user can achieve in the different conditions and also the main différences that he can identify between those different kinds of auditory feedbacks.

Conclusions :
Experiments in immersive environment aiming at improving the quality of auditory feedback and at comparing different methods.
