I’m going to stick up for him too. Some of his examples are stupid, but some are correct. And some of the concepts are correct, but he could have used better examples.
Take, for example, the door issue. Simple solution - you put a handle on the side that you’re supposed to pull, and a push plate on the side you’re supposed to push. Then no one EVER gets confused. The doors in the picture aren’t too bad, because at least it’s obvious which side they are hinged on. But if you’ve ever seen those glass doors where you can’t even tell which side they are hinged on, and they have those horizontal bars on each side of the door, then you’ve essentially got a one in four chance of getting it right the first time you open the door: You could push or pull on the hinge side, or pull on the side you should push, and all three of those attempts will fail.
His example with the metronome is dead on as well. It would have been much better if the front had had up and down arrow push buttons, and a linear tempo scale on the side. Make sure the scale goes the same direction as the arrow (ie if you push the ‘up’ arrow to go faster, the faster stuff on the scale goes to the top). The functionality is then immediately obvious.
These are trivial things, but good usability design is all about the trivial things. For example, my Escape has a power seat switch which is very good - it’s a long plastic bar sticking out of the side of the seat. Pull up on the front of the bar, and the front of the seat lifts. pull up on the back, and the back lifts. Slide the whole bar back and forth, and the whole seat moves back and forth. Simple, intuitive. No manuals required. On another car I had the seat control was a complex series of buttons, and I could never hit the right button on the first try.
His point about the ticket vending machine is correct as well. We have those machines here in Edmonton. To use them, you have to push a button for the ticket you want. Then the price comes up on a screen. Then you put in your money until the ‘price’ window drops to zero. Once it hits zero, the ticket comes out automatically. What’s wrong with this? EVERY other vending machine I’ve ever used works the other way around. You feed money in, then you pick something to buy. By reversing the order, you force everyone to stop and read the instructions to do something they’ve known how to do since childhood - buy stuff from a vending machine. In this case, the lesson is that standardization is a good thing.
I also liked his point about shampoo and conditioner being in bottles that look the same. More than once I’ve purchased conditioner when I needed shampoo - this is especially likely because often people would pick up conditioner when they wanted shampoo, then seeing their mistake put the conditioner back - with the shampoo. So no you’re forced to stop and read the little bottle to make sure you buy the right stuff. I never have that problem buying, say, Kraft Dinner. And what makes it worse, if you buy shampoo and conditioner from the same manufacturer and have it in your shower, then if you’re almost blind without your glasses it can be almost impossible to tell which is which in the shower when you need to the most.
