  • 1. M y research: Spatial SoundControl w ith the iOS device S1170144 Ryo K anno
  • 2. A bstract In m y thesis, I describe the system for controlling“ Spatial sound ” w ith the iOS device. A sm artphone , likeiOS device, had a touch panel on it ’ s display, and canquantify the position w here w e touch as a com binationof x and y coordinates. Based on this quantifiedpositional inform ation, I aim to establish a new systemfor controlling spatial sound and enable iOS devices to bea new interface of virtual reality.
  • 3. Spatial Sound Spatial sound is one of the im portant soundexpression in virtual reality, and has sam e m eaning of“ stereophony ” or “ 3D surround ” . It includes thesound of direction, range, yew , depth (near and far),elevation, and so on. In virtual reality, w e can enjoym ore realistic sound by com binating these featureseffectively.
  • 4. Previous W ork Tw o years ago, a previous thesis, “ Spatial SoundControl w ith the Yam aha Tenori - on ” w as published.M y research succeeds and extends this, aim ing to allow the sound m ore sm oothly and freely m ovem ent around a space. Figure: Yam aha Tenori - on, the new type of m usical interface
  • 5. Research A rchitecture Spatial Sound Control is realized via W i - Fi. The quantified positional inform ation is sent from iOS device to CV E server through the iOS - CV E bridge, and sent from CV E to control PC. ( iOS - CV E bridge is the program for helping com m unication betw een iOS and CV E server.)Finally, control PC changes spatial sound in realtim e based on received positionalInform ation.
  • 6. Flow of Research 1 First, I create a application for getting positionalinform ation from touch panel. To achieve this, asource code of draw ing application w ill be leveraged.These application are w ritten by objective - C.
  • 7. Flow of Research 2 Then, a com m unication system betw een iOS deviceand com puter is also needed. I leverage theCollaborative V irtual E nvironm ent (CV E ) server toconnect these device to each other. This system hasalm ost been com pleted in previous research (as I said,this program is called “ iOS - CV E bridge), so I use andextend it.
  • 8. Flow of Research Finally, based on received positional information, I create a program for controlling spatial sound in realtime. A s a programm ing language, "Pure D ata", real-time graphical programm ing environm ent for m ultimedia is used.
