High-speed ultrasound-field control using phased arrays of transducers (PATs) have allowed creating interactive multimodal (i.e. visual, haptics and audio) displays in mid-air. We introduce some algorithmic and technical advances in PATs that have allowed such high update rates (i.e. >10 kfps), having shifted from the high-speed single-point algorithm to the high-speed multipoint one.
