Walk buttons at pedestrian crossings in Germany

The wide variety of walk buttons inspired this post. I’ll cover the three types I’ve personally come across, but surely there are more.

Let’s start with the worst example. This one here is apparently touch sensitive, but touching the red dot results in absolutely nothing. There is no feedback and no way for you to know if you actually did something (it may as well be a placebo button). It’s so bad that they actually put a large label to explain the usage. And they even messed up the label! It’s written in both German and English, but there’s no separation between the two (and clearly “Touch” is not the direct English translation of “Fußgänger roten Knopf bitte berühren”).

Now this next one’s a bit better. It’s also touch sensitive, but at least once it registers your action it displays a red sign which tells you everything’s fine. It’s certainly better than the previous example. So what’s the problem here? Well I just don’t like this “let’s use touch sensors to seem more technologically advanced” attitude. I’ve seen people (young and old) trying to press it in all kinds of ways – from touching it gently with one finger, through pressing it 3-4 times just to be sure, to slapping it as hard as possible with the whole palm. And of course the only way to be sure you did it right is to look directly at the device and wait for the red sign.

And here’s my favourite – simple, robust and reliable. It has a real button in the form of a large plate that clearly affords pressing. There’s strong haptic feedback and you’ll be sure of your actions. If not – there’s a red lamp on top (just in case). Too bad someone labeled this as outdated technology, because in my opinion it’s still the best.
