Help - How do I open this door!
There's no way to intuitively know how to open the doors where I work. The handle--a bar that spans the width of the door--looks like it can be pulled or pushed. What's more, some doors you push to open, and some you pull, and it's completely arbitrary, at least as far as I can tell.
In fact there's one way you can tell what action to take. There's a mechanism at the top of every door. If it's on your side, you push. If it's on the other side you pull. So every time I go to open a door I instinctively look up. I don't break my stride, and it's all very easy. Problem solved.
But I shouldn't have to look up anymore. I mean there are only 4 sets of doors I open on a daily basis. I should know by know which ones I pull and which I push. I should have had that memorized already. Wait...this is leading somewhere design related, read on...
The mechanism at the top of each door was pointed out to me by a coworker. Had he not relayed this useful bit of information I would probably have soon thereafter memorized the door situation, and never have needed to rely on looking upwards. In fact I was on my way towards doing so. I was in the process of constructing a mental model of the pattern of push/pulls that made sense to me; mental models give their owners intuitive understanding of objects and how they are to be interacted with. In this case I was coming up with some sort of construct that rationalized the seeming arbitrariness of the direction the doors swing, a construct that would be intuitive enough to allow me open each door without thinking.
I no longer need to do this, though, because looking up is easier than constructing that mental model, (perhaps because the doors do swing completely arbitrarily, and any model I conceive would be somewhat contrived, and therefore not really that useful). The point is, that I ceased my efforts to find that model, and stuck with what was easy--looking up. And I really never though about that consciously until now. How many other interactions in my day to day life--in all of our day to day lives-- are made up of those same patterns of subconscious thought--finding the easiest way to do something, without ever really thinking about it.
