This is why I detest touchscreens for most car functions. Specifically AC, with old fashioned knobs I have full control over AC without taking my eyes off the road, but nowadays everyone wants to put it on their infotainment system, hidden beneath 4 other buttons.
The emergency brake. I really need that to be a mechanical lever and not an electrical one. If something is going wrong on the road I need a backup brake that takes me under a second to activate while in a state of panic with my eyes glued to the road and it had better be functional.

Re: US Navy will replace touchscreen with mechanical controls on its destroyers
#272You know, I think touchscreens are not preferable unless you need/want to be able to have controls for many different systems in the same space (e.g. a smartphone with multiple apps). If you are needing a dedicated control for a high-stakes system, the fact that it's a more modern-looking interface should not matter. Touchscreens are inherently inferior to a mechanical interface, if it's a single-system (i.e. doesn't…
What I have: There's one button that toggles A/C on/off; when it's on, a green LED glows in the button (the button is flush at all times). There's an up/down lever that increases/ decreases the fan speed: hold it up, and the fan speed increases by a notch every second or two, and similarly for down. When you let go, the lever reverts to the middle position. The fan speed shows in a series of bars in a tiny display above that switch. There's another up/down lever that controls the temp setting, although exactly what that does depends on whether the A/C is on (I think). Its current setting shows as numbers above that switch. There's another controller that determines whether the air goes to the front seat only, or the front + back; the setting for that appears on the main console screen, but only for a few seconds after you change it--after that, the main console reverts to showing engine status or something, depending on how that's set. Whether it goes to the driver only, or to the driver + front seat passenger, is determined by whether the car thinks there's a passenger (which it determines by weight on the seat). There are two other controls that determine whether the defrosters are on; I can't remember how you tell what they're set for.
What I wish: two knobs to control temp and fan settings; clockwise would be higher/ faster. A lever to determine air to the front/back seats. A toggle switch to turn the A/C on/off; up is on. Toggle switches for the front/rear defrosters.
What I'm glad I don't have: touch screen controls for all this.

Rear fog lights: something more cars should have in the US for this exact situation.
Or fewer. The only time I ever see them on is when it's a clear night and I'm getting blinded by the person in front of me. That said, they are pretty useful for more than fog... They're good for flashing at people behind you who don't have their headlights on.

Manual works just fine. I just drove clear across the Trans-Canadian Highway, east to west, in a car with manual controls and it all worked great. Your eyes stay on the road because sober people can reach out and grab objects, like knobs or buttons, without looking. If the matter of defrosting confuses you then maybe you should sit down in your car for five minutes and learn how the multi-ton machine works before att…
One: I think we can discuss this without condescension for anyone who doesn't agree with you. Two: You are making a false choice: Automatic settings need not replace manual ones. Essentially what we are talking about is a spot on the dial that says "auto" which you are free to not use, much like headlight controls on higher end cars.
Well, they worked fine, but my A/C just went out, so getting dehumidified air is a problem these days.

> I detest touchscreens for most car functions Agreed. I consider them dangerous, a threat to public safety, they should be banned by the NTSB, and some cars that use them should be under recall to retrofit them with mechanical controls. Many states are now passing hands free laws that criminalize the use of phones or any other devices that use your hands while driving. The states provide exceptions for car touch scr…
I had this discussion with my teenage child this week and neither of us are sure. Our state requires handsfree phone use but has the car touchscreen exception. Would operating Android Auto or CarPlay be illegal or does it fall under the allowed exceptions?

You know, when you take your drivers test in the US, you have to demonstrate your ability to know where all those functions are before you even pull away to start your test.
The real question, as I found yesterday, is can you switch on high-speed wipers, rear fog lights, hazard lights, and max-demist, in a few seconds, while you're devoting 99% of your brainpower to not crashing into an unseen vehicle slowing in front, not veering out of the lane that you can't really see, and glancing repeatedly in the mirror in case you're about to be rear-ended. The question is not whether you can ope…
And if it's really, really bad, pull over. Don't be like those idiots who decide to stop in the middle of a highway with 75mph traffic around them, under an overpass to protect themselves from a hailstorm.

Right. For anything dynamic , an interface that can redraw itself in milliseconds has enormous advantages over mechanical knobs and levers. For managing permanent properties, I think mechanical interfaces are the best option, though of course vastly more costly.
You are right, but I think it goes beyond that. Any control interface is by definition acting on something dynamic, so even pushing a physical button, we expect the some status to reflect the result instantly. I think touchscreen could be best used as a step above joysticks, when an action cannot just be summed by a on/off (or +/-) state, or a vector in one direction. Imagine in a military setting if you need to open…
Re: US Navy will replace touchscreen with mechanical controls on its destroyers
#279Wait. Let me get this straight. Touchscreens, which are ideal for representing multiple user unterfaces in an intuitive way, but requiring constant visual contact are being replaced by a physical user interface that can be used by both touch, and memory? Why was touchscreen ever even a consideration for controls you're not looking at? Touchscreen is great for phones. It is awful for keyboards (see macbook pro). And i…
Of _course_ they did.
But nobody listens to the UX/HCI researchers and academics, when the touchscreen vendor's sales team are inviting them to fully catered lunches on a tropical golf course...
Business as usual.

Honest question: Why don't modern cars yet monitor humidity in and outside the car and make the correct decisions to keep your windows clear? Why are we focusing on self-driving cars while our cars are too dumb to do this much on their own?
Why don't cars have 2 batteries? One for starting the car, and the other for all the crap that tends to kill the battery when you most need it? Probably because it costs more money and nobody will pay for it. That's the best guess I have.
