  1. Audio for Telepresence and Virtual Reality Colin S. Harrison

  2. Objective is to enhance sense of hearing for Telepresence and integrate with Virtual Environment Laboratory • Replicate feeling of being there • Hear a sound – turn to look at it • Replicate human hearing • Localise azimuth, elevation, range, properly externalised • Use audio to augment video for improved sensation of presence

  3. Human 3D Spatial Hearing • Differences in Time (ITD) • Differences in Intensity (IID) • Movable Head • Pinnae Filtering (Head Related Transfer Function)

  4. Implementation • Binaural sound / Simulated head • (HRTF) for Headphones • Integrate with Telepresence Projects • B-Format for loudspeakers • Integrate with VE aspects: ABACUS suite • Lake DSP for Headtracked Binaural Simulation and Loudspeaker reproduction

  5. Originality • Binaural -Two eared technique • Ear/sensor assembly • Mechatronic head • World first system • with physical binaural sensors • B-Format approach for Telepresence ( new Application) • No other UK VE site has installed realistic sound

  6. Virtual Environment Integration • Link to existing Virtual Environment Laboratory • Add realistic sound to VE presentations of architectural projects • Change sound as position and room type changes Publications • Conference Paper: (Mechatronics 98) • Journal Paper: (by invitation Mechatronics)

  7. Industrial Relevance • Hostile human environments • Remote Military Intervention • Nuclear Chemical -Chernobyl • Surveillance (Big Brother hears you too!) • Entertainment • Architectural walkthroughs

  8. And Finally • Telepresence: seamlessly represent senses: consider a Turing Test • Accurate sound triggers sense memories
