Modeling spatial sound in contextual augmented reality environments

This paper describes spatial sound modeling in Contextual Augmented Reality Environments (CARE) with the use of the CARL language. To support 3D sound presentation in CARE environments, the CARL language has been extended with new sound elements. The concept has been implemented in the CARL Browser that enables displaying augmented reality presentations enriched with 3D sound. As a result, extended CARE environments enable combining visual and audio content in AR scenes in a flexible and seamless way.
