Problem of poor sensitivity of audio touch screen
« on: August 09, 2018, 04:56:05 PM »
Hi,   

We have a Jazz SE, bought new May 2017 (UK spec, GK chassis).  Our son uses it for his short commute to work, gets irritated by the regular radio traffic announcements, and turns that feature off.  I use it for assorted trips evenings and weekends, and value the traffic warnings.  I understand the only way to turn them on or off is through the touch screen.

I start the car, reverse off the drive, and as I start to weave my way between the cars parked on our close, the standard warning appears on the screen.  I touch the OK "button" that should clear it, but usually nothing happens.  I try again, and after a few attempts the warning goes, and I can set TA on.  Sometimes my wife is with me, but the screen doesnít respond any better to her finger.  Iíve tried things like pressing hard on the screen, tapping rather than pressing, and licking my finger, but havenít found a reliable way to clear the warning.  (I have a smartphone, and that responds readily when I touch it.) 

The need to clear this warning is a dangerous distraction, which shouldnít be necessary for each journey now that we are all too familiar with it, but I understand weíre stuck with the warning.

Do others have difficulty getting this message to clear?

What is the best way to operate the touch screen with your hand?  Does anyone know the physical properties to which these screens respond?  I wonder if I could keep a small block of a suitable material handy in the car, press it against the screen, and get the message to clear reliably on my first attempt?


With thanks,
Chris

I never have any issues but I know that others have in the past.  There is certainly no need to press it hard or tap it.  I just usually rest my finger on it and it reacts ok.

FYI, I also have never had an issue clearing the warning message with a normal tap.

I also have no problem with the touch screen response but I usually turn off the warning before I start as itís hard to hit the button while driving as your hand tends to wave about and is not as accurate. Iíve always thought touch screens are a bad idea in a car as you canít feel the buttons

Iíve commented a long time ago about the insensitivity of the touch screen:
https://clubjazz.org/forum/index.php?topic=7602.msg35876#msg35876
https://clubjazz.org/forum/index.php?topic=7845.msg38088#msg38088
As have other owners in this thread:
https://clubjazz.org/forum/index.php?topic=7574.msg35619#msg35619
I guess Iím used to it now though. As Ralph suggests, it may actually simply be that itís difficult to hit the sweet spot on the screen whilst driving. I totally agree with his comment that a touch screen is a bad idea in a car because you have to look at it carefully in order to tap the right spot, thereby taking your attention off the road, but itís the trendy thing to have so weíre stuck with it.

I am a bit surprised by your description of how long it takes the warning screen to appear:
I start the car, reverse off the drive, and as I start to weave my way between the cars parked on our close, the standard warning appears on the screen.
I find the warning appears as soon as I start the engine, and certainly before Iíve moved off, so itís no particular hardship to cancel it before I actually start driving. Or just leave it and the screen will dim anyway.

Thanks for the responses so far.  My preceding search did find the posts you mentioned, ColinB, so I was aware some others had problems, but hadnít given a solution.

From the responses, I think itíll be worth get it running on the drive and trying to find whether I need to touch a particular ďsweet spotĒ within the ďbuttonĒ.  Previously Iíve tried pressing the ball of my thumb on the ďbuttonĒ to make sure Iíve covered the crucial spot, if there is one; maybe it needs to be touched there but nowhere else.

If we didnít have the TA on/off issue, Iíd happily leave the screen warning to fade; Iíve already decided itís much easier and safer to use the buttons on the steering wheel to change channel and volume, although I canít find them until Iím out of our curvy close onto the straight road.  Our ageing Primera is so much easier and safer, with a volume control knob and physical TA and pre-tuned channel selection buttons on the dashboard!

Our drive slopes up towards the garage.  I check that itís clear behind, start the engine, release the handbrake and let the car roll round the corner, and I think the warning appears shortly after Iíve engaged forward gear, but immediately thereís a branch of the close that comes in from the right, so Iím looking out for other cars on the move at the time.  I tried to estimate the timing when I was a passenger with my son last weekend, and I guess it took between 5 and 10 seconds for the warning to appear.  I really donít want to sit on the drive after starting the engine, wasting fuel and time, waiting while the warning appears and I then take several attempts to clear it before turning on TA!

I, and navigator, both have trouble cancelling the OK message. Swearing, sometimes helps!

The only reliable, canceller, is our little grandaughter. I guess, her fingers are more moist, than ours......

I intend to try a phone, touch screen prodder.

I've not had a huge problem but I occasionally miss the [Ok]. It doesn't seem particularly bad to me. Sounds like the OP has a faulty unit or needs to calibrate it (does it have a calibration function?).

Do tell us what you do with the ten seconds you save, stopping at a red traffic light must be a disaster and as for traffic...  Ten seconds of fuel use, do you really measure your fuel consumption to a tenth of a teaspoon?

Thatís only the time before the message appears.  It usually takes more time to clear it than for it to appear.  And environmentalists seem very keen that we should reduce emissions by not having engines ticking over when stationary.  Of course I wouldnít mind a delay like that if it was for a useful purpose, or necessary such as when clearing misted or frosty windows.  I scorn motorists who canít even wait to do up their seat belts before they get on the move.  But having to clear that same message every time I want to use the car is irritating enough, without having to sit there with the engine running waiting for it to appear, and then trying to remove it through a system that doesnít work properly.

The index finger on my right had was badly scarred through a burn many years ago. It now looks normal but there is little sensitivity due to scar tissue. As a result, touchscreens often refuse to recognise it and a tap usually fails and I have to carefully place my finger on one to activate it.

Applies to Iphone, satnav and others.. I try to avoid touch screens..(my thumb is no better and I lack half  an index finger  on my left hand so am short of options)

It wouldn't be so bad if at least the screen reverted to showing the time if you ignored the warning. Ideally a full-size graphic with the option to choose the way it looked. In fact I think that'd be a big improvement as it would give the vehicle an easily readable clock.

But no. Due to the ineptitude of those who designed the software the screen just goes almost entirely black. Apart from the time. Yes, really, it's there! In the usual position, top right. Far too dim to read except at night. It lights up if the current audio source sends a 'track change' signal.

I despair at some of what passes for UI design these days. It's just thoughtless.

A couple of further thoughts on the original enquiry.

How clean is your screen ? Any dust or fingerprint deposits might make it less sensitive.

An irritation with the RDS TA system implemented on the Jazz is that if you get an announcement that isn't relevant to where you are, you want to get rid of it quickly: the only obvious way  to do that is using the touchscreen so you're back to the prod-several-times-and-hope problem. I went for a long time cursing that until someone in this forum pointed out that you can cancel the announcement quickly using the "Hang-Up" phone button (the centre one of the three on the lower left quadrant of the steering wheel). I don't think that's in the handbook so might not be widely known. Maybe if your son is informed about that he'd be more inclined to leave TA switched on when he has the car ?

I clean my screen regularly, about once a month, with anti static plastic polish. I don't have any problems with screen insensitivity.

Do I detect a little "I want it now!" Impatience? The only problem I have had (once) was prodding the screen after moving off and changing the language instead of clearing the "If you crash the car it's your fault" message.

If only, everyone's fingers, worked to the same parameters! Mine are affected by a lifetime in Engineering......

The prodder, works instantly.....




And now lives, here. For instant access.....




It perfectly, matches the colour of the car, too!  ;)
