We are really at the early days of touchscreen technology. While audio feedback and advances in haptic feedback could make this slightly more viable, I see touchscreens as an interim workaround on the journey towards gestural (+ audio) input. The mistake in this design shown in the video is (in my opinion) using a touchscreen at all - i.e. a 'touch ...

Others have focused on the psychological effect of the practice, primarily with relation to sales. But I'd like to focus on what one should think of with a speedometer that is free of these sort of plots. Different countries different rules In places like Germany or the Isle of Man, there are highways on which there are no speed limits. Different ...

Thought I'd throw my two penneth in as a former Automotive Interaction Designer for a large British car manufacturer in the premium and off-road/footballer market owned by an even larger Indian company. Starts with "Jag", ends with "...nd rover" Anyhow, for those of you familiar with those brands you'll know they use touchscreens. I'm not a fan. The NHSTA ...

My previous car (a Volvo) seemed to solve this problem very well: You turn the car off and the lights turn off automatically. If you need the lights on, you leave the key in position I or II (Intermediate/Accessory and Drive positions). If you have the keys on your person, your car's lights are off.

Driving is complicated for any first timer. That is why you have driving schools teaching you how to do it. The most challenging thing there is not the gear shifting, but dealing with traffic. The gear shifts you propose do exist. They originate from the racing world, and Top Gear's Jeremy Clarkson refers to them as "flappy paddle gearbox". They allow ...

To expand a bit on jamesqf's answer, while the airlines decide much of the interior layout, window placement is driven by structural elements of the aircraft. An airliner fuselage has a series of circular frames, and windows go in the gaps between these frames: You can't really change the window alignment without changing frame spacing, and doing that is ...

I would say it has to do with the following reasons : Contrast : Studies have shown that black or dark backgrounds provide the easiest contrast and can allow users to read discrete information quickly without having to make an effort to discern details when in a dark environment (which is often the environment in cars) Darkness adaptive : Another reason ...

From: http://www.pbs.org/newshour/making-sense/why-do-cars-have-fuel-doors-on/ Putting fuel filler doors on different sides of different cars thus means that some cars can access pumps from the left. And this makes it less likely that drivers will have to wait in line for gas. That benefit greatly outweighs the cost of occasionally pulling up to the ...

I believe it is in part because text in all-caps have a clear, regular rectangular shape to them regardless of the word or language, making them easier to position uniformly on any shape. That is, there are no descenders or ascenders to accommodate as there would be with lower-cased words (the position of which might vary depending on the word or language). ...

I think that wouldn't it make more sense to partition the battery such that even if the lights are left on, by the time they die, that the car still has enough reserve charge to start. This still follows your requirement that the lights must not be switched off by any electronic system as the lights only die when they use up the charge in the partition of ...

The problem is that seat layouts are something that is decided by the airlines, not the aircraft manufacturer. There are a large number of possible seat layouts for any particular model, for instance http://www.airbus.com/aircraftfamilies/passengeraircraft/a330family/a330-300/cabin-layout/ In addition, seat layouts for any particular plane might be ...

I asked my father just this question forty years ago. His answer then was that it was a hangover from early designs, particularly when petrol stations looked like this: Most drivers pulled in at a pump on their side of the road, which means that most arrivals would have the passenger side of the car adjacent to the pumps. It was all attended service, so ...

In summary: Because of mechanical constraints and cost Tradition The interface is optimized for experienced users The interface for a manual transmission is somewhat complex because it's a historical design driven by technological limitations. The shifter in most cars with a stick is still a mechanical linkage pushing around bits of steel inside a very ...

You want a driving simulator that simulates the cognitive, visual, and physical workloads of the primary driving task. A game, unless specifically designed to simulate driving without including other non-driving activities (racing, shooting, collecting point, etc.), will not suffice. Here are several options. CARS An open source project requiring a PC, a ...

I am assuming that people are now comfortable giving control to the car. One model that I would expect to see replicated is railway train pod / "London Hackney carriage" seating. download bmml source – Wireframes created with Balsamiq Mockups Some aspects likely are Primary seats are in the back Sliding door to single compartment Seats face ...

Here are some reasons why they are not more prevelant Users havent demanded it. Its not something users care about enough in surveys or in customer feedback for automobile manufactures to include it. If it was a must have they would all be researching it and developing different concepts to compete in the HUD space. Your speed isnt a primary focus to when ...

As others have mentioned, this is very much a safety issue and very much worth asking! Fortunately, user experience in vehicles has a long history of study and standardization. SAE International, formerly the Society of Automotive Engineers, has published a number of standards and papers related to this issue. Here are some that may be relevant: ...

Car makers have developed various systems to reduce the risk: Beeps when you open the driver's door with the lights on, beeps and alarms when you try to lock the car with the lights on or a door open, inner light switching off after some time or when the keys are out of range. One important detail is even though such systems exist since a long time, not all ...

You say "any electronic system must never switch off headlights", but there are a few cars that have automatic mode for headlights. The cars have a photocell somewhere to detect brightness, and will toggle the headlights accordingly. They typically have a feature that when the driver leaves the car, the lights will remain on for 30 seconds or so, before ...

This is very definitely a safety design. What you will find is a feature known as "auto reverse", this means when the window is going up if a obstruction is detected it will sense it and go back down. In America this feature was/is required with vehicles that have "one touch up" (what you have described). I have found several sources saying this is ...

Speedometers are an good example of UX hierarchy of needs The aspirational speed markings (e.g. above 130mph) are functionally useless for many cars, but they enhance the driver's experience by providing the illusion of performance for drivers who have spent tens or even hundreds of thousands of dollars on their car. Aspirational markers may be ...

Upper case words usually take longer to read, since we are used to most of the letters being lower case, however, since the words in the car are Short Not read like a text, only searched for Small The upper case has an advantage: Since the words are short - there is no need to read them Upper case stands out - better for scanning Upper case makes the ...

As far as a driving simulator, what type of additional resources are you talking about? You can put together a decent simulator using a mid level desktop, usb steering wheel and gas pedal and 42" TV running Need for Speed, or some other game driving game. (Granted, a system like this does not give the user experience of the tactile feel of driving) What ...

With a self-driving car everybody in it will behave like a passenger. What do you do when you're a passenger? Read a book, listen to music, watch a movie, interact with other passengers, do some work, sing a song, make a phone call, watch the scenery, do a power nap, counting cows... The interior will be adjusted to the most important activities. Facing ...

Interesting question. Looking around online, it seems to be a combination of marketing (makes the consumer think the engine is powerful) and manufacturing efficiency (can use the same speedometer in faster cars as well as minivans). http://mentalfloss.com/article/59478/why-do-car-speedometers-list-speeds-are-way-over-legal-limit

Actually, the US is one of the few places to have enforced a limit on the maximum speed shown on a speedometer (reportedly to stop people trying to "speed test" their vehicles). For vehicles produced from 1979 to 1981, you'd only see vehicles showing up to 85mph: *The same law dictated the highlight at 55mph ...

A common affordance which informs users about cars reversing in india is the use of audio tunes to inform the user that the car is currently in reverse. Though its a very good affordance which immediately informs the user and the people around him that the car is in reverse, it does suffer from the issue of contributing the noise pollution and also the ...

Manual transmissions may not be "highly usable" but they are a "highly learnable" interaction. Once you learn a stick, all you have to do is rest your hand on it to know where it is. Also, you learn how a car "feels" so that if you're at 40 miles per hour, you know how the car feels in third and fourth gears respectively. Learnability is better to design ...

A few solutions could be: Color coding on shifter - Forward moving gears could be colored green while reverse is left white. Red wouldn't be ideal since that's so closely related to 'stop'. There are problems with this approach because does white clearly mean reverse? Would a user be looking at the gear when choosing them? Could the graphic on the gear ...
