The form praised on that article is horrific UI. Makes me want to scream and pull out my hair. That someone created this abomenation is one thing but to praise it is the funniest thing of my day (one should have such things)
If you put a form in front of someone with fields like name and address when they are requesting a quote you don't go put "personal info" at the top... in a red font?? If it is important you use a larger font, red is for drama. We have bullshit draining the attention.
The same goes for "Address correction", the user is not to stupid to see the form is returned to them.
It gets worse from there....
"We could not find the address you entered"
If it was an IRL person to person interaction this is all you would say. No screaming or drama required.
Some elaboration would be nice. If you do that properly there is no need to vaguely talk about the address in general.
"Entered street name was not found"
Imagine that, ask yourself, would it be useful to also say you couldn't find the address?
But we have stuff between those two things to further confuse the user. I don't know the situation but if they may continue despite not finding the address you should probably just accept the address.
It gets even worse from here... We've told them we cant find the street name but the house number is also incorrect??? wha how?
I haven't the slightest what "Directional incorrect" means, maybe and/or works differently in the US.
We don't know what St means in a street name?
If one may make changes or continue with the address provided. How will the user know his changes are correct? If they want to continue as~is they cant be presented with "Address correction" again. You would need two submit buttons.
And finally, the truly most terrible part is that the "errors(?)" are not described above or below the form field they apply to.
We get this wall of complicated text where a few lines should have been enough.
As this is page 1 out of 8 the odds people will run away from the computer screaming are greatly improved.
