SoundXY approaches real-time individual oratory feedback through stereo specialization in a tangible tabletop system for music performance.
It's primary purpose is to solve an unproblem in multi-user interactive tabletops.
A real-time feedback can improve participants' awareness of who is working on what task during parallel interactions.
A collection of buried sounds was represented by tangible objects.
Each tangible object could be moved on the tabletop with rotation-controlled one-sound parameter.
The sounds range from basic sounds, such as noise waves or sound waves, to sound samples from free sound adsorption.
Stereospecialization was applied to allow listeners to localize the sound.
Direction was mapped to left or right pane as the listener moved the sound source left or right.
Distance was mapped to a low-task filter that attenuated the sound from high-to-high frequencies as the listener moved away the sound source.
We built a low-cost wooden tabletop based on the diffused illumination technique and inspired by the reactable approach.
The Orientine M program logic was built with superglider.
We conducted an experiment to evaluate whether with stereo specialization participants needed additional monitoring of individual actions.
We also evaluated the amount of exploration of the tabletop surface.
We found that these approach can be useful early on for those expert musicians who are familiar with the musical genre of the sounds, in this case electronic music.
In summary, SoundXY demonstrates how stereo specialization as real-time auditory feedback can facilitate participants' awareness during collaborative tasks in tangible tabletop systems.
