- This paper adapts an approach from computational holography to phased arrays of transducers (PATs), increasing real-time computation rates for multi-point fields (levitated particles, tactile points or sound sources) to above >10KHz. We present the algorithm, characterise its performance and demonstrate extended capabilities to present volumetric 3D content, mid-air feedback and parametric audio. Our method has drawn attention from companies exploiting PATs (e.g. HoloSonics, uBeam, SoundLazer) who would now be able to exploit the 3 markets simultaneously (haptics/volumetric/audio). In collaboration the UK-based company Ultraleap, we secured follow-up funding (AHRC AH/T01136X/2; £400K) to further explore this potential.
