SMART-I2: “Spatial multi-user audio-visual real-time interactive interface”, A broadcast application context

SMART-I² is a high quality 3D audio-visual interactive rendering system. In SMART-I², the screen is also used as a multichannel loudspeaker. The spatial audio rendering is based on Wave Field Synthesis, an approach that creates a coherent spatial perception of a spatial sound scene over a large listening area. The azimuth localization accuracy of the system has been verified by a perceptual experiment. Contrary to conventional systems, SMART-I² is able to realize a high degree of 3D audio-visual integration with almost no compromise on either the audio or the graphics rendering quality. Such a system can provide benefits to a wide range of applications.
