However, we also used the study as an opportunity to probe the general feasibility
of dynamic patterns. We introduced a dynamic circular pattern, where the vibration
signal moves along the wheel (i.e. a vibration signal starts at actuator 1 with full intensity, then after 300ms the vibration stops and starts immediately at actuator 2 for
the same time with the same intensity and so on). The idea is to lead the driver to turn
the wheel in the correct direction by following the moving signal, i.e. when it moves
from left to right the driver should turn to the right and vice versa. Dynamic patterns
are also an interesting alternative, since they are not affected by extreme turns of the
steering wheel and could transmit more complex information. Integrating many small
actuators into the wheel would allow the signal to quickly move between adjacent
actuators, enabling the user to, for example, feel the vibration move along the fingers
of one hand.
