Hi,
I am investigating a concept for the center stack of a car. Does
anyone know what effects auditive and/or haptic feedback on car touch
screens - have on the user experience?

The concern is that the driver is already affected by things like
bumps, vibrations and sounds.

So, if there is a touch screen in the car (similar to iPhone), how is
'added' sound or haptic feedback experienced?

Ex Scenario.
The driver wants to select a new song.
He drags a list (think iPhone) to choose a new song.
If there is auditive or haptic feedback -ex. a 'tic-sound' for each
song - it might assist the driver so she does not have to look at the
screen for a) confirmation of that she is in fact browsing the list;
b) knowing how much she has manipulated the list.

What are your thoughts?
Have anyone experienced this kind of interaction in a car (ex. using
iPhone) with auditive feedback? - or using a haptic screen when
driving?
Does anyone know of studies/research related to the topic? links?

If I'm wearing gloves, probably not at all. It's winter where I live --
on short trips the car doesn't get warm enough for me to bother taking
my gloves off.

I recently purchased a new car cd/radio, or "in-car entertainment
system", and the lack of useful audio feedback is truly annoying. I can
pick one of a dozen colors to flash in tempo to the music; when I change
the volume I get animated soundwaves displayed on the console; but the
only audio feedback is the occasional generic beep. Doing anything
more than adjusting the volume requires me to move my active focus from
driving to looking at a complex UI. I'm not sure that's such a good
thing for me to be doing while I drive.

I have no data or metrics to point to, only anecdotes from my own
experience using a GPS.

And yes, sound was extremely important. Sound was the primary
feedback for using the device. It let me know what icons I was
pressing on-screen, using different sounds for forward or backward
menu navigation. And it seemed that the designer had put some real
work into how the unit used voice as a way to remind the driver of
upcoming turns and lane changes. It was extremely useful, and never
once confusing or distracting.

This has been done, using haptic feedback, by Lexus:

I haven't tried it, but I've read reviews that say it's so good it
should be in every car.

Thanks for the link, Victor. I hadn't heard of Remote Touch before. I
like the haptic feedback idea, but positioning a cursor while driving
seems like a bad idea to me. One of the benefits of an iPhone-like,
touch-oriented menu in a vehicle setting is that you don't have to
think about the relative positioning of a cursor on the screen.

A solution that I'd get excited about would be a touch screen with
haptic feedback. Basically inlay an iPad into your car's dash and
give the user tactile confirmation on button clicks, selection
changes, etc.

Assuming people will expect to be able to adjust the controls of the
car while driving, I think the aim is to help the driver keep his/her
eyes on the road. And if you can *feel* the controls you don't need
to look at them, the screen can be supplementary, or for the
passenger.

Great to see all the comments, certainly gave me some ideas, and also
some more things to think about.
I've read about lexus before but never really seen/heard any
comments on how their tactile/haptic feedback actually feels like;
the sensation so to speak. So, that would be interesting to try to
find out.

Touch screen with haptic and/or sound feedback was my initial
interest (not remote). Personally, I think it is important to be
'careful' about using sounds. But as you say, and from own
experience, Dave & JE, it is also an important factor. Thanks.
