       | I applaud the author for putting thought into how to design
       | digital controls, in contrast to the "just put whatever garbage
       | on a touch screen" strategy most carmakers do today.
       | 
       | However, I still question the benefit of this complex, modal
       | control (you have to press a single knob to "cycle between"
       | multiple modes). My ancient, 2016 car features three knobs. This
       | luxury allows me to, without looking, adjust any of three
       | settings (temp, fan, air location), as well as a button which
       | does each seat heater, without any "check what mode it's in, tap,
       | look at the tiny screen, tap again if necessary" step.
       | 
       | True, in this trim, my car does not have a thermostat mode, which
       | in theory is useful, but it is so trivial to modulate the
       | temperature based on "do I feel cold, hot or comfortable right
       | now" and reaching over to twist one of the controls anyway, and
       | even in the other car I have which has this mode, I frequently
       | need to adjust things anyway, except in that car some of the
       | functions require multiple mode changes on the touch screen and
       | looking away from the road.

         | I've changed the channel tuner when I've reached for the volume
         | knob. If the haptic feedback between the two is clearly
         | different, that will help, no?

           | Controls that require a feedback loop have more cognitive

           | includes not having to check for haptic feedback to test what
           | mode it's in) and from pure muscle memory. For example, you
           | learn that your preferred volume when driving on a highway is
           | at (say) the two o'clock position, and with time you'll
           | blindly turn the knob to that position without even
           | consciously thinking about it. If, on the other hand, you
           | "know" that the knob could be in a wrong mode, you'll tend to
           | hesitate when operating it because of that anticipation,
           | having to check back whether the knob is indeed in the
           | correct mode.

             | Right. This "smart" knob is symmetrical, with no pointer
             | that you can feel before turning the knob. So it's hard to
             | use without looking. This is inferior to a simple
             | mechanical knob.

               | rather than absolute, so the physical positioning at
               | power-up is unknown. Thus, the physical knob can't have a
               | physical pointer with consistent behavior.
               | 
               | I have an LG washing machine with a knob like that. After
               | power up, you have to turn it one notch before it lights
               | up to indicate the current position, which is the default
               | Normal cycle. So the knob has to be symmetrical, with no
               | tactile pointer.

           | I've found one good solution to this problem (for AC, at
           | least): go for a car with a good "auto" mode!
           | 
           | I hardly ever touch my AC, I just leave it on auto and the
           | car does the rest to get it to the right temperature as
           | quickly as possible.
           | 
           | I suspect this is what most automakers think the real

               | by providing relatively cool air from the dash vents only
               | on that side. It also knows not to do this on a cloudy

       | 
       | A. Trying to design down to two knobs makes each knob multi-
       | modal. This removes a lot of muscle memory benefits requiring a
       | glance at a screen, a small screen that is now partially covered

       | 
       | B. Haptic feedback... will this work with gloves on? (will you
       | feel it, will it sense your touch)
       | 
       | A lot of manual systems now have 3 knobs, not much more than the
       | 2 presented here, which will always do the same thing each time
       | you reach for them. My concern would be how long it would take

       | really physical controls. They are buttons and dials that are re-
       | programmable. Even the aperture ring on my lens is not physically

       | the body to do the same. There are wheel-button thingies on the
       | front and the back that you can bind to whatever.
       | 
       | Cars basically could use controls like that. Maybe with some
       | sensible defaults; and there's going to be a bunch of things that
       | most people would like to control with a button or a dial. Not
       | that hard to execute and you can sell cars with more and less
       | dials. Or no dials at all. The touch screen is always the cheap
       | fallback. The buttons are a nice up-sell. And with the right APIs
       | and wireless protocols, it wouldn't even be too hard to have
       | third party bluetooth buttons even; or a strip of buttons that
       | plugs in a USB socket. Or similar. You can buy flight simulator
       | hardware that emulate most of a modern cockpit with physical

       | things are pretty affordable even. Throttle compartments, landing
       | gear buttons, buttons with a satisfying click/thunk/etc. Whatever
       | you want.
       | 
       | Like it or not, this stuff is basically cost related. Buttons
       | have lots of wires, components, etc. That increases cost of
       | assembly and bill of materials. They can also break and cause
       | additional cost under warranty. People need training on how to
       | install and repair that stuff. The nice thing with a touch screen
       | is that it's just a handful of components and wires. Installs in
       | no time and if it breaks, it's easy to replace.
       | 
       | So, the question for manufacturers then becomes what is the car
       | with the least buttons that drivers still pay a premium for?
       | Because, that's the most profitable for them. And the reality of
       | course is that what people say what they'll buy mostly doesn't
       | match their behavior in the show room.
       | 
       | It's the same with a lot of products. It doesn't matter whether

       | only think they know and talk themselves into buying crap they
       | definitely are not going to be happy with.
       | 
       | In the end, people mostly just select the thing with the largest
       | feature matrix that still fits their budget. And the nice thing
       | with software features is that there's no assembly or component
       | cost involved. Modern cars are smart phones with wheels.

       |

       | WHAT?!?!!

       | the cabin. Amazing.
       | 
       | So I still hate the controls but I wouldn't give up instant
       | heating to fix them. Obviously I'd rather have instant heating
       | AND sane controls. I just never knew what i valued as a user

       | https://en.wikipedia.org/wiki/Fitts%27s_law
       | 
       | It seems that many synth UI designers have small, thin, bony
       | fingers, and overlook the issues that comes from having knobs
       | placed too close together. They like to design tight, compact,
       | "valuable looking" knob panels, and I like to inform them that
       | these designs are nonsense and some consideration should be given
       | to the spacing of things.
       | 
       | This has an impact on the end user with fat fingers, since moving
       | one knob should not provide the opportunity to accidentally
       | 'bump' or 'jog' another adjacent knob - there simply has to be
       | space to allow for market finger types.
       | 
       | (In spite of the fact that these are mostly German designers,
       | asking them to review their designs in the context of automative
       | controls, has been a herculean effort.)
       | 
       | So one of my favourite toys in my arsenal when confronted with a
       | new, fresh-faced designer full of impactful and dense design
       | ideas, is an Arduino with an LCD display attached to a
       | breadboard, and 4 movable knobs which can be placed in an
       | approximation of the design. I wrote a tool that displays a UI
       | with a fine-tune parameter, and whenever I get a chance I lay out
       | the knobs using the designers intended dimensions, and ask them
       | to fine-tune the parameter.
       | 
       | If they can do it one-handed without bumping other knobs (and
       | thus triggering the :P emoji and siren noise), they get a pass
       | and a check-mark on their design doc.
       | 
       | If, however, their dimensions make it impossible to move only a
       | single knob, they get a little :P mark on their review documents,
       | and my designer-killer tool gets put back in the drawer for
       | another day.
