In this experiment, participants could ‘‘feel” the 3D path once
they encountered it. Phenomenologically, it was as if the stylus was ‘‘magnetically attracted” to the path1
. The curved paths
were inspired by and, therefore, similar to a ‘bead maze’. These toys are commonly found in pediatrician waiting rooms and
consist of brightly colored curved ‘roller coaster’ wires with beads on them that can be pushed along the wires by a child.
