Notice how the texture of the trim knob | is different than other controls. When cost is no barrier, you | can have mechanical switches, toggles, flip-off guards, various | shapes and sizes of knobs, levers, color coding, hazard markings, | etc. - all made from top notch materials and you bet, the haptics | were totally engineered for best possible way to reduce | ambiguity. Aesthetics take a back seat. | | Also, props to the narrator. She was to the point and well | informed. | | I hope UI/UX designers (even for web design), industrial | designers, architects, ergonomicists, HMI designers be inspired | from this with one major take away - stop putting personal taste, | aesthetics, decoration, marketing, etc. before functionality and | pragmatism. Especially those working in vehicle interior design - | people need to realize we drive a deadly 2-ton machine on our | roads. Make no mistake, modern regression of UI in cars is | because of bean counters - touchscreens are vastly cheaper than | physical encoders/switches/toggles, especially automotive grade | ones. [1] | | Can you imagine if you had to flip a toggle switch to turn | bluetooth on in your car? I know you're smiling from just the | thought of it. People make the case that UI needs to be simple | for people to use at the expense of density, but remember - we | already look at the world which is very messy and navigate it | without a problem. Millions navigate through airports. People | knew how to use Yellow Pages (extreme density) and telephone | books. Making UI more understandable is orthogonal to information | density. | | Unrelated: It is a shame that SpaceX's dragon crew cockpit design | ditched all this in favor of a more sexier (arguable) looking | sci-fi aesthetics. IMO it looks like a cheap movie set including | the space suits. | | [1] | https://www.mouser.com/ALPS/Electromechanical/Encoders/_/N-3... | trynewideas wrote: | > Also, props to the narrator.

Most people doing web design do not have the luxury of | putting a vast area of functionality flat on the page and | knowing that your users will be trained and intimately aware | of each and every function. | starpilot wrote: | SpaceX said Dragon would probably be safer if it were fully | automated, but they added more opportunities for human control | to appease NASA/astronauts. | avalys wrote: | > Especially those working in vehicle interior design - people | need to realize we drive a deadly 2-ton machine on our roads. | | This sounds very smart and serious, which must be why someone | makes the same point in literally every discussion of a control | interface for some kind of vehicle - but I challenge you to | provide evidence that fixable UX problems in modern automobiles | have led to an increase in accident rates. | | In fact, most modern vehicles use touchscreens to solve the | very problem that you are supposedly concerned about. Rather | than a complicated cockpit full of individual buttons and | switches to control every single function, most modern cars | have a few easy-to-find buttons and switches for functions you | might want to access while driving (i.e. radio volume, climate | temperature, fan speed), and use the touchscreen to hide all | the more complicated and lesser-used settings out of the way! | | Do you really think that putting your grandmother into a car | that resembled that F-15 cockpit would be a safer option? What | happens if she forgets where the button is to, say, turn on the | A/C compressor? Is she going to read every single label while | cruising down the highway at 75 mph? | itsoktocry wrote: | > _What happens if she forgets where the button is to, say, | turn on the A /C compressor?

Have you ever seen a 75 year old | use a computer? I think physical switches are more intuitive | to someone that age. | systemvoltage wrote: | I have about 104 physical switches at my disposal that I | use to type this comment. | systemvoltage wrote: | > hide all the more complicated and lesser-used settings out | of the way! | | Why? Just looking at more stuff makes you nervous? Ever been | to a library? Ever cooked a meal? Ever walked outside your | house? The world is full of complex "UI". This is a total | bullshit minimalism case designers make to satiate their own | personal taste. | | I would like to see data that proves that "seeing" more stuff | impedes the ability to operate something. Hiding stuff is | detrimental, I would argue. The hierarchy of menus is equally | as complicated as a dashboard of logically laid out | "containers", each box decidated to a specific group of | functions. It is _exactly_ the same! Your vision system scans | through the top level hierachy (Climate Control, Radio, | Vehicle Settings, Navigation), then focusing in on individual | controls (akin to sub-menu items). The benefits are massive - | immediate control, haptics feedback, muscle memory, etc. | Negatives a minor and can be addressed - cost, reliability | and durability (wearing off labels for example). The problem | is - if you look at ALPS catalog of encoders, they are | rapidly going _up_ in prices because automotive manufacturers | are ditching them and they don 't have enough volume to | sustain production and keep costs down. If we had invested in | this industry, we would have kept the costs down too. The sad | thing is, they are discontinuining a lot of physical | controls. | | > Do you really think that putting your grandmother into a | car that resembled that F-15 cockpit would be a safer option? | What happens if she forgets where the button is to, say, turn | on the A/C compressor? Is she going to read every single | label while cruising down the highway at 75 mph? | | Actually yes. Thank god we have knobs and buttons left for | A/C controls. Why didn't hide that in the menus? Apart from a | few cars, most cars have physical controls for climate and | radio. | | Grandma's kitchen is probably 10x complicated than car UI. | She does just fine. | TeMPOraL wrote: | > _I would like to see data that proves that "seeing" more | stuff impedes the ability to operate something._ | | Edward Tufte made a career out of writing books that | essentially argue this for data design: information density | is _good_. Low information density means you 're wasting | people's time. | | Our visual systems are extremely good at creating and | navigating hierarchies, at rapidly switching between levels | of detail, and at actively filtering irrelevant | information. You don't have to hide stuff, you just have to | make the user determine it's irrelevant for the task at | hand, and their brain will just filter it out. | | (See also: banner blindness.) | avalys wrote: | Quick, look at a picture of the F-15 cockpit, and find | the switch to set the LANTIRN pod from Day mode to Night | mode. Now imagine you're in a car and you can't take your | eyes off the road for more than a few seconds. | | Airplanes are much easier than cars in that regard - once | you're airborne there's not much to hit! | TeMPOraL wrote: | We're comparing it to cars with touchscreens, and I | guarantee you that the first time I find that switch | (parked in the garage), I'll remember where it is later. | With a touchscreen, I'll always have to look. | | Also, neither a car nor a fighter jet assumes an | untrained operator. We can't forget that you get a few | dozen hours of practical training before you're allowed | to drive unsupervised, and that's more than enough to | familiarize yourself with the user interface. | | So the question boils down to: does the interface | facilitate operating without looking at it, or not? | Physical buttons do. Non-shit touchscreen UIs could, but | they don't exist. Touchscreens used in practice don't. | avalys wrote: | "Seeing more stuff" makes it harder to find the one thing | you want without taking your eyes off the road. A | touchscreen or similar interface in a car allows you to | maintain a minimal set of buttons and controls for access | to essential functionality while driving, while keeping the | complex and infrequently-used stuff hidden in the | touchscreen for access while stopped (when you have as much | time as you need to search through the interface finding | the thing you want). | | I agree that putting controls which you need to use while | driving behind a touchscreen is not an optimal choice. | Dahoon wrote: | Excuse me if I misread your post but it sounds to me as if | what you are saying is that touchscreens are safer? Tests | have been made that show that even using Apple carplay with | voice is worse than old buttons. It has also been shown to be | worse than the drunk driving limit. | | Here is one: https://www.driving.co.uk/news/apple-carplay- | android-auto-wo... | avalys wrote: | The point I'm making is that touchscreens can lead to a | safer _system_ because they allow you to optimize and | simplify the layout of the buttons that remain after you've | moved the infrequently-used functionality into the | touchscreen. | zoomablemind wrote: | Physical switches also seem to require more deliberate action, | unlike the touch controls, where the the act of touching is not | much different from an accidental touch. | | It's interesting to learn that F-22 side-stick had to be modded | to add more physical deflection movement vs. a sensitive but | nearly monolith handle. This was requested by the pilots | accustomed to effort feedback common to earlier gen of the | planes. | zokier wrote: | I do point out that the F-15 cockpit is from the 70s and it | shows.

The | operator training part has to do more with the domain of | knowledge (how to back up the trailer, for e.g.) than with | the UI. IMO UI can be "complex" and yet understandable if the | layout is logical, everything is labelled and the _domain is | already understood_. We all know what _Turn on bluetooth_ | means. Whether it is hidden in 4 level deep menu in a | touchscreen or immediately accessible with a toggle switch | makes no difference IMO. In fact, I would argue that a toggle | switch is _easier_ than digging into Menu > Vehicle Settings | > Entertainment > Phone > Bluetooth. More importantly, it is | discoverable. | | Please don't dig too much into the bluetooth thing, it is | just a example that I want to use to make the more general | point. | rzzzt wrote: | Not UI, but you mentioned one part where software could | really shine: instead of getting the feel of the "inverted | pendulum" driving in reverse with a trailer, what if I | could just turn the wheel where I want to go and let the | computer figure out how to keep the back in line without | jackknifing on itself. | | (I am also sure such software exists, and it fares poorly, | otherwise it would be a standard accessory on trucks and | everyone would have forgotten how to do it "by ear" by | now.) | scott_s wrote: | I don't disagree with your response, but I disagree with | what I understand to be your initial point: the primary | reason that the F-15's interface is this particular way is | because cost was not a barrier. While that is part of it, I | don't think it's most of it. I pointed out operator | training time, which is assumed to be huge. | | But there's also a fundamental difference between a fighter | pilot and someone driving a car. For a fighter pilot, | everything they have to be able to do has to be at a hand's | reach in a second. This is an operational requirement for | both the "fighter" and "pilot" sides. Driving a car is | different; there are many tasks that normal car drivers | don't need to do _while driving_. It 's okay for them to do | them parked, after fiddling with a bunch of other stuff. | | My point: it's not just cost which determines the | difference, but training and task requirements. | systemvoltage wrote: | > It's okay for them to do them parked, after fiddling | with a bunch of other stuff. | | Point noted. Commercial airplanes also have that in the | form a FMS: | https://en.wikipedia.org/wiki/Flight_management_system | | A menu system just like cars except no touchscreens, | although I heard that's changing. | technothrasher wrote: | Anybody who enjoyed this would likely enjoy the Fighter Jet | Podcast by ex-Navy pilot Vincent Aiello.

In normal conditions escaping an | aggressor would not be such situation. | | Think it as redline in a car; take away the limit and the | engine can rev higher and possibly get few hp more, but the | engine won't be in any good shape after that. | roelschroeven wrote: | VMAX adds 2% to the max RPM of the engines, giving a bit of | extra performance for when it is really needed. In the process | it increases wear and tear on the engine, necessitating an | expensive very thorough inspection and possibly repair of the | engines. | | If your life depends on it, by all means use it. In all other | circumstances, save the maintenance crew the extra work and the | taxpayer the extra costs. | dpe82 wrote: | A lot of fighters have "emergency power" controls that will | push the engine past its normally rated power band for a short | time at the cost of drastically shortening the life of the | engine. I would guess that's what this is and why pilots are | normally forbidden from using it. | evgen wrote: | As a more historical example of this, a lot of WWII fighters | had a max power setting on the throttle that had a wire | strung across it, but the pilot could break past the wire to | go to 'War Emergency Power' and gain anywhere from 15-50%+ | more horsepower from the engine. The use had to be logged and | after a few hours of this the engine would need to get a | complete tear-down and rebuild. | | It is basically a 'you are trading away this engine to save | your life' setting, but sometimes that was a necessary thing | to do. | jeffbee wrote: | It's very interesting that engineers can compute this | threshold to a 2% error. | kens wrote: | This extra boost of power is also known as "War Emergency | Power", and goes back to World War II planes. In the P51 | Mustang, WEP increased the horsepower by 61%. But after using | WEP, the engines needed to be inspected before flying again, so | it was only used when necessary. | | https://en.wikipedia.org/wiki/War_emergency_power | | Related is the "Battle short" switch on Navy computers, which | shorts the fuses with copper bars and disables over-temperature | faults, so you can keep the computer running during a battle | even if things are going bad. ___________________________________________________________________ (page generated 2020-07-01 23:00 UTC)
