Hyundai Promises To Keep Buttons In Cars Because Touchscreen Controls Are Dangerous (thedrive.com) 145

Posted by BeauHD from the tried-and-true dept.
An anonymous reader quotes a report from The Drive: Sang Yup Lee, Hyundai's head of design, reiterated the company's commitment to buttons at the introduction of the new Hyundai Kona. As reported by CarsGuide, for the Korean automaker, it's a decision rooted in safety concerns. "We have used the physical buttons quite significantly the last few years. For me, the safety-related buttons have to be a hard key," said Lee. It's a design call that makes a lot of sense. In some modern vehicles, adjusting things like the volume or climate control settings can require diving into menus on a touch screen, or using your eyes to find a touch control on the dash. In comparison, the tactile feedback of real buttons, dials, and switches lets drivers keep their eyes on the road instead.

"When you're driving, it's hard to control it. This is why when it's a hard key it's easy to sense and feel it," said Lee. As far as he is concerned, physical controls are a necessity for anything that could impact safety. Hence the physical buttons and dials for items like the HVAC system and volume control. Lee hinted that while this is a priority for Hyundai today, things may change in future. In particular, the company will likely look at using touch controls more heavily when autonomous driving becomes mainstream. "When it comes to Level 4 autonomous driving, then we'll have everything soft key," said Lee.

Everything you would commonly need while moving was right there. You still needed to pull over to program the sat nav, but still it wasn't bad. On some levels I still miss that car. It was incredible to drive, but it just wasn't a good replacement for my Aston.

        The move to touchscreens was accelerated by Tesla, really, because the Tesla's huge 17" display was so "futuristic" that everyone copied them to show their cars were very advanced.

        Touch controls are nice to provide controls that aren't used often - e.g., if you need to set the clock (like adjust for daylight saving time) - it saves having to overload buttons or provide dedicated buttons for functions that aren't used a lot. Touch controls are also useful where you may need a lot of buttons to avoid having to have a ton of button for functions that don't require such functionality all the time - think on screen keyboards when trying to navigate. Aircraft often have dedicated keyboards because a lot of text is entered prior to and during the flight, but most cars don't have a need for a dedicated text entry system. Especially if the text entry can be done elsewhere and later synced (e.g., contact lists, or destinations which may be pre-programmed in your phone).

        But common features, like headlights, wipers, climate controls are used so often they should have dedicated buttons/switches or stalk controls.

        It also makes design easier - remember on a Tesla things like the defoggers are on the touchscreen, causing a major safety issue if the touchscreen fails that led to a recall. A simple defogger button would eliminate that.

        Heck, you can offer both interfaces - a knob to adjust the volume of the infotainment system, but you can also put a slider on the screen to adjust the volume so if you're messing around with the controls on the touchscreen, the control is right there rather than having to find the knob and rotate it.

        Honestly there are multiple fundamental problems here beyond just the touch screen. Why on earth do you need to play with any heating or cooling at all during driving. It's 2023. We know the conditions that result in people changing a heating or cooling configuration. We have technology that can hold houses within 0.5C of a target temperature and even compensate for radiated "comfort" i.e. sun shining through the window.

        It shouldn't be hard for a car to actually control climate in a way that I set my desired temperature at the start of the trip and then never touch it again.

      More worrisome is what happens when a touchscreen fails and starts sending off false signals in the middle of driving (changing the volume, radio station, or worse yet the environmentals). I've had it happen in the past. In fact these days I keep a small washcloth in the car to ensure I wipe it before starting occasionally, to ensure that the touchscreen doesn't get dust/pollen buildup that can cause this by throwing off the calibration.

      Having the touchscreen start changing things while the car is in motion at random is incredibly distracting and dangerous for the driver.

      There's also the situation where knobs have been inappropriately replaced with buttons: in my MkV VW GTI, a really nice car by most measures, it took about 9 button presses to get the A/C to max cool upon getting in on a hot day. This on the "upgrade" climate controls. I think the stock config had knobs and no degree indicators.

      By contrast, in my (sadly missed) MkV GTI all it took was one good CCW whip of the temp knob to get cold air. Thankfully my current Tacoma is sorta similar in temp controls.

If you look at the cockpit of a modern aircraft, like the Airbus A350 airliner, or the F-35 fighter, you mainly will see large screens, some of them touchscreens, but there are still plenty of physical controls for the important parts, in convenient locations, and recognizable by touch. You can also control what's on the screens with physical buttons.

      The difference is that aircraft manufacturers actually care about ergonomics and safety, that's because people who buy and fly planes are professionals and the plane is their work tool. Car manufacturers mostly care about making their interior look cool because it is what sells, and also cheap, because they have tight margins and everything counts.

  • What about physical buttons that are on the edges of the screen and can even change functions depending on what "mode" you're in? The current usage of the button can be displayed on the screen right next to it. The button could even be transparent and placed over the screen, so its legend can change as needed?

  • Getting in a strange relatively high end car of a different make than you're used to is always an instant learning curve to find the important buttons. With time and practice you can find them without looking but it still takes practice.

    A Touch Screen is arguably a bit more of a radical shift but again with a little practice it gets to feel quite natural for the most part, there are still a few awkward points that are readily bridged with voice commands but even that is uncommon.

    Sure the guy is perfectly right, but why does he even need to state this? Putting anything safety-relevant on a touchscreen in a car should lead to instant, full liability for any and all accidents that causes.

    I don't understand why the automakers keep getting rid of physical buttons for safety critical systems. They save some money up front but the back end liability can be substantial.

    Take for example Tesla. They had to perform recalls because their touchscreen systems eventually wore out the flash memory on the Tegra 3 processors and the screen stopped working. You would think fine-- if the car is under warranty, Tesla needs to fix, otherwise the owners are on the hook. But because the screen controlled safety features such as windshield defrost and back-up camera, Tesla needed to do a recall even on cars well past the warranty period.

    Screens (with or without touchscreen) to control safety features seems like such a bad idea on so many levels. Windshield defrost should be one button press away at all times.

    • ...Windshield defrost should be one button press away at all times.

      I agree! That's why I docked mine on the always availble ribbon at the bottom. One touch.

        Ha ha, I love your confidence in Tesla. My parents had a situation last month where the defrost button somehow undocked itself in a Model Y and they did not know where to find the substitute. They didn't notice until they really needed it in the latest east coast ice storm, Lucky they tried voice control and it worked, but it's not a great feeling when the button you docked somewhere disappears. There can be other issues too, for example I still remember driving across the country in 2016 in my Model S, did a software update just prior to departure, then realizing at the worse possible time that my defrost button turned into a freeze button. Almost caused an accident as my windshield froze amazingly quickly and I had to pull off a highway in the dark with my head out the window. Another update a day later fixed it, but from the forums I was not the only one caught by this bug. Last but now least, Tesla MCU reboots itself periodically even while driving, how do you turn on your defrost when your MCU is rebooting?

        The other problem is that the buttons move over time. When I bought my first 2 Model S, the buttons were at the top, suddenly they moved to the bottom, later got buried into some depth of menus, then at least I was able to "dock it" as you say at the bottom, but had to learn that first. There isn't always time in the morning after receiving an OTA to go learn a whole new UI.

  • I have a 2015 Subaru with what I guess is called a climate control upgrade package. There's a large knob with tactical feedback to change the interior temperature. Some days I want it set at 71F, some days maybe 74F, easy peasy. The only other button I ever touch is the one for the the rear window defroster and then only on those rare days when it's needed. How difficult can this really be?
    • I want to change the air direction as well - sometimes I like it blowing on my feet, sometimes I want it on my face, sometimes I need front defrost. I DON'T want the fucking cum-pooter running the car deciding what's best for me in this respect ... if I want cool air on my face, I don't want to be second-guessed by HAL 900.

      Complex control UIs and stress are well known problems. That should have been addressed at system testing, if not earlier, but that's a whole different subject.
  • I so agree with this!
  • Touch screen avionics (aircraft electronics) makers have shunned touchscreen displays for the same reasons listed here. Of course, that didn't stop the replacement of GPS/Nav systems with Ipads.

  • 4 corners and the middle, active on release. That way you can hit the touchscreen anywhere, slide to a corner and release, or back away from that corner for the 5th "button". The border of the touchscreen needs to have a raised bevel.

    Anything else sucks in a vehicle - you have to be able to use the controls by feel, not by sight.

    In my current car, I can operate most things without taking my eyes off the road. It has voice control but I rarely use it except for navigation where while I can enter destinations without looking (it has a place where you can draw letters with your finger and it'll acknowledge them via voice) it's faster to use the voice control.

    I twice (5 years apart) rejected both Volvo and Tesla in favour of BMW with the physical controls being a major part of the decision.Porsche was my only other consideration and again, they get ergonomics for a driver. Voice controls aren't perfect and frankly when driving I want to control many things WITHOUT needing to devote unnecessary brain power or focus on it.
