Agree with both of the above answers -- get users right into the interaction and link off for an explanation of "How It Works". Different context, with different constraints, but 23andMe does a pretty good job of minimizing what could be a really complicated explanation, see https://www.23andme.com/.

Apple's word isn't final when it comes to UI design, but they make it a point to talk about this in the iOS Human Interface Guidelines: As much as possible, avoid displaying a splash screen or other startup experience. It’s best when users can begin using your app immediately. The barrier to entry should be as low as possible for first-time users. ...

Where I live in Australia (a place very rarely affected by snow cover), speed limits are painted on the roads only when they change: Image from Teach Yourself Driving in Australia Regular speed limit signs are also posted both at the point where the limit changes and many times along a roadway as a simple reminder or for commuters that have joined a ...

In Phoenix, we don't have the MPH written on the road in our highways, but we do have the highway that this is an exit-only lane for written on the road. For example, you're travelling on the 202W, and there's an exit for the 101N coming up. Before the exit, there's an on-ramp from another street and after that on-ramp (and before the exit) there's an ...

The lines are used with Gatso speed cameras as a secondary check of distance travelled. They are precisely laid in the road surface and the Gatso takes 2 pictures 0.5 sec apart. Whilst the Gatso will register the speed from the radar (and only trigger the camera if the pre-set limit is exceeded) the number of lines uncovered between the two pictures will ...

It facilitates reading the text in moderate traffic. If there are other vehicles on the road and you are following at a safe distance, you will read the closer text first as your view of the farther text will be blocked. This allows you to read the full message incrementally. Obviously this breaks down when there is no traffic and you have decent vision, ...

Extreme Environmental Conditions Similar to conditions in Finland, as shown by @locationunknown, locations in India suffer problems as well. Where monsoon damages roads every year. Imagine speed limits and other markings on road would never be seen on these roads. Other constraints here in India, why speed limits are not on road is the sheer ...

Apparently (I have been unable to locate the research), A UK study showed that in slow, dense traffic drivers would spend more time looking at the road surface directly ahead of their vehicle but in light, fast-moving traffic would spend more time looking further ahead. In the first case this would offer a lower view and the in the second a higher view. As ...

In complete agreement with the other answers, but to provide an alternate viewpoint: If you were driving at night, your headlights will reveal the beginning of the sentence before the end.

You read as you approach. Theoretically. In reality, levels of visual acuity mean that some people (like you and I) can read the whole block at once. Another reason that painting information on the pavement isn't always ideal. Here's a good visual for how this is designed to function in practice: The trick is (as the image above shows) the spacing of ...

I have bad vision. I can see well enough to drive, but if that message is more than a line or two, I won't be able to read the beginning of it before I've passed the end of it. They're written backwards for me.

A more technological solution would be for the speed limit to appear as part of a heads up display for the driver. This could enable the sign to be given extra emphasis when the speed limit is being approached or broken. More simply the car could just be fitted with a speed limiter that adjusts to the local restriction so that no speed limit signs would be ...

Do signs printed on the road offer a significant advantage for the user over signs on a post? Let's make a matrix: ------------------------------------------------------------------------------- | On Road | On Sign ...

Besides the snow-covered roads—a very clear reason but only applicable in a small number of cases—there are several vision-related explanations. The first one is simply geometrical. On an empty road, a traffic sign remains for a long time close to the centre of the driver's field of view (where vision is sharpest) and can be seen from far away. It gets off ...

Also, information printed on the road can only be read when there is little traffic, or at least no cars blocking it (or other obstacles such as weather as already previously stated). In rush hour, for example, your speed limit on the road would likely be missed by everyone. The same would happen even if you were driving at the speed limit and there was a ...

Here in Finland the main reason is this: Image source Road markings are used to denote speed limits but never as a primary mean. And as Jung Lee points out, re-applying road paint is labor intensive, especially here, as studded tyres usually erode most of the paint in one or two winters. Edit: The Finnish law actually states that road markings, such as ...

In addition to the ones mentioned by others, here are additional considerations: Road paint is more labor intensive to install initially. Road paint is more labor intensive to maintain as well because road needs to be repaved every few years and/or potholes filled. But more importantly, road paint is slippery in wet weather. (well known concerns among ...

Couple of reasons: When driving there are often cars ahead, so anything written on the road can be obscured. The same is true with street signs, but it's not nearly as bad. Drivers look forward and straight. Signs are usually off to either side of the road, where both a driver and passenger can see. Thus the signs are a little easier to view for all ...

I would say there are a couple of aspects here Line of sight : Though while driving your line of sight is mainly on the road, the main point of focus is at object ahead of you straight ahead (e.g. a vehicle going ahead). Hence writing the speed signs on the road would have to require the person driving to focus down and assimilate the information which ...

I think you should design both, why not? I think a navigation that works without burger menu is better for visibility, but sometimes it's unavoidable on mobile platforms.

In my experience: Property Grids focus on consistent, simplified programmability, whereas a dialog caters to task-specific UX, leaving more room for "manual UX optimization". Property grids are usually "driven"*) by a generic enumeration of available properties and their types (where type defines valid values and method of input). With such an API in ...

Here are some of my thoughts on login: Only ask the user to login if its absolutely necessary: With this in mind if the user only needs to be logged in to use 10% of your app make sure they can use the other 90% without being logged in. When your app first launches if the user doesn't need to login to start using it don't ask them to do it or if you do ...

Check out this page, it has a lot of login screens. As you can see there, there are many options, including the options you provided. I wouldn't dare to say there is a best practice, given there are tons of options you could consider. What I would say, though, is to consider these things: Is a login/signup really neccessary? Is there nothing the user could ...

In order to show data is related in the same table there is a 3 step process. Put the data next to the related elements (you did) Show some classification of which data fields are related (you did) Tell the user why its related! Because it may not be obvious See my design. You could alternate colors between the related fields and maybe when they hover ...

Your current approach is heading in the right direction. When your users use this data regularly, they will already know the relationship between the groups. Switching background color is one way of creating contrast between groups. Other ways would be to use line separators and white space. One thing you can have do to make it more obvious is by ...

Use grouping horizontal lines and eliminate the verticals one. Horizontal lines helps to lead the eye along the line, while vertical lines become a barrier along the eye path:

It looks fine to me, I believe the terminology "we host a version for you" isn't great, perhaps:
