There is a type of anatomical movement
that is present across countless musical instruments,
from ancient prehistory up to the present:
up and down fingertip movement, relative to a surface.
What if technology would make the forces that influence this movement
Both the rejecting
attracting forces, down to the fine details?
The cyclotactor system was created from scratch for this purpose.
Force transfer to the human fingerpad occurs in mid-air,
while avoiding the use of connected mechanical parts
moving relative to the target anatomical site.
This enables precise I/O at high bandwidth.
