Design for Dead Simple Distinction, originally uploaded by edross.

Imagine it is 6am, and you've wondered downstairs to make you and your wife
a cup of tea each. She likes goat's milk, but you have cow's milk. As it is
so early, the parts of your body that are required for reading are not quite
fully functional yet, but your taste buds are, and you don't want to end up
drinking tea that tastes of a Greek salad. How are you supposed to pour the
right milk in the right cup?

In the case of Tesco, they have come up with quite a simple, but effective
way to differentiate between the two types of milk: the bottle of one has
the handle in the middle, and the other has the handle on the edge.

Even at your most blurry eyed moment, you should be able to feel around for
the edge and the middle of the bottle and tell which is which!

And so there you have it: one small way in which the design of an every-day
object has helped increase its usability. Can you think of any other
examples? If so, please let me know in the comments section below.
