Infrared Optical Gesture Controller for 3D Spatial Audio Trajectories (Revision 5.3)
Discipline: Perceptual Interfaces · Lead Researcher: Dr. Yuna Takahashi
OPERATIONAL ABSTRACT
A contactless desktop instrument that translates three-dimensional hand gestures into multichannel spatial sound trajectories and filter sweeps. Enhanced revision 5 with improved low-noise shielding and updated real-time firmware.
TECHNICAL SUMMARY & TRANSDUCTION DYNAMICS
Time-of-flight infrared optical sensors measure hand position in X, Y, and Z axes with 1mm accuracy, sending low-latency Open Sound Control messages to spatial decoders. Calibrated for studio and field use under ZIAA experimental protocols. Harmonic distortion measured under 0.02% across primary operating range.
