It has already been demonstrated that visual feedback is
an
inadequate means of driver input. Furthermore, no one
really wants to look while they are driving, but they still
want the freedom to drive. So let's make the visual
spectrum redundant.
The position, direction and velocity of
cars around you is
translated into a symphony of sound. Really it could be
programmed to translate basic factors into whatever you
like, but here's one example. Suppose a large
vehicle which comes up behind you, passes you and your
left, and cuts you off. You would hear the following:
As the vehicle approaches from behind you, you hear a
low
b flat quickly pulsing at a constant rate from the rear
speaker slowly gaining in volume. He accelerates as he
changes lanes to pass you, you hear this as an
acceleration
of the pulsing, and a gradual change in speakers from
the
rear to the left. All the while, volume is increasing as
the
car overtakes you, only decreasing after you've been
passed. As he cuts you off, you hear a brief acceleration
in
the pulsing as the sound switches to the front speaker,
and
begins to fade in volume as he zooms ahead.
The driver can set parameters, or call out key and mode
changes, as well as "conduct" the symphony by driving
erratically. If your artistic whims require that B-flat to
increase in tempo more quickly, simply slam on your
brakes as it approaches from behind.
Signs are sung to you at predefined special notes
according to type. "stop stop stop STOP STOP".
The vehicle itself becomes a percussion idiophone.
Also eliminates that problem where you are looking at
the smartphone and can't see that the light has changed
and everyone is moving.
