Inept UI (User Interfaces) surround us. We only have to step out anywhere and inhale deeply, and their heady fragrances pervade our consciousness.

In today’s example, I was speaking at a conference in Brussels last week and encountered this bathroom faucet configuration in the hotel room. See anything odd?
Brussels faucets

Take a closer look:
Brussels Handle

That's it. There's no handle, only a gentle, graduated knurling around the side which you can see here if you look closely, focus, and be the faucet. The faucet is stiff to begin with, so with wet or soapy hands (and remember, it’s a bathroom faucet, right?), the knob is unturnable.

Good user interfaces combine ease of use with pleasing visual, tactile and aural designs. Bad ones sacrifice function to appearance. This one is bad.
