My campus is the proud home of the McCormick Tribune Campus Center which, despite being incredibly beautiful, has some of the most frustrating bathrooms known to mankind. This is due to the faucets having a totally different interface from every other faucet ever. To turn on the water, one must wave their hand in front of an infrared sensor. To turn it off, one must do the same thing again. The amount of water this building wastes because visitors expect the faucets to turn off automatically is not known to me, but I assume it to be quite large.
Why am I talking about faucets? The faucets in the MTCC break a common user interface that is familiar to people, who respond by being confused. Learning a new way to do a familiar task will never be intuative. This is a basic human limitation based on functional fixedness. I believe that this is why risks are so seldom taken in interface design. Burnout from the pre-standards days of websites, where mystery meat navigation was common practice, may also be a strong contributor.
As rational as the current approaches are, they are also self limiting. Fortunately, I think interface is going in a new place entirely.
Welcome to the new interface
The search bar is quickly becoming the primary interface tool for everything. I launch every application on my computer with quicksilver, which is infinitely faster than anything else. I don’t type URLs anymore, I search google for the name of the site. I’ve stopped meticulously organizing files on my desktop; every month I just throw the entire contents in a zip and move it to an archive folder.
The search bar has moved organizational emphasis away from the filing cabinet/folder system that we are so used to. The emphasis is on having a good idea of what you are looking for, not on knowing where to find it. Good search features have also cut down on our need to meticulously organize everything so that we may later retrieve it.
There is still a lot of work left and creating better and better search algorithms is an extremely difficult task. Nevertheless, organization and interface is moving in the search bar direction.
