We at the London conference and in the U.K., the cars drive on the left side of the street, whereas in most of the rest of Europe and the rest of the world, the cars drive on the right side of the street. Now, there’s no inherent reason it’s better to drive on the right or better to drive on the left. Just pick one and do it everywhere.
That’s the old useability principle of consistency. But since they don’t do that, it’s really a grave danger when you go to a country that drive on the wrong side of the street, because when you are a pedestrian, you try to cross the street. He was just used to looking in the other the wrong direction and therefore you may well be run over. Now, luckily, they recognize that here in London and Cervetti painted on into the intersections and area says, look left or look right or whatever it may may be. I’m sure that the sign is said a lot of lives over the years. So this is a great example of Just-In-Time help, which is a little message that you get right in the situation where you need that information. This is in great contrast to most other type of health information where users have mainly recognized over the years that help doesn’t most help, does not really help you. It’s just a waste of time. And users don’t go and read online documentation manuals that doesn’t see this as a manual for a website.
But just in time, help is in fact helpful. So if you can find those situations where users are going to be confused about something or need to know a little bit more about something, because it before they can continue right there, you can put the help information. And that’s something people will in fact read, at least if it if it’s written properly. But that’s something that people will read and use and that will be helpful. So just in time, help, just like at the London intersections.
