I need (to do the) exercise(s).

I guess I’ve dilly-dallied long enough with these usability exercises, so i’ll try to get something done. Since I’m a fan of doing things the wrong way around I’ll start with the definition thingy.

A tennis ball* is a specialized piece of sporting equipment designed for optimal performance on the tennis court. A tennis ball is manufactured out of the finest natural and/or synthetic rubbers in order to create an optimal amount of inertia, or bounce. The hollow rubber ball encases a bubble of air which, together with the elasticity of the rubber, stores and releases energy whenever the ball is hit, thus making the ball bouncy. The surface of a tennis ball is usually covered with a green or yellow fibre mesh for optimal friction, or grip.

A golf ball* is a specialized piece of sporting equipment designed for optimal performance on a golf course. A golf ball consists of a hard rubber core which is covered with a white or yellow shell of flexible yet tough plastic. The surface of the plastic shell has a uniform dent pattern for optimal grip.

* A ball is usually a round toy or object for playing sporty games.

There, I’ve done it. I didn’t quite know whether to go into too much detail with the definitions, so I made the one about the golf ball a lot simpler. It’s questionable whether end-users of such products understand certain specific physical phenomena, such as inertia. Then again it’s quite hard to come up with a sufficient definition without going into at least some detail with the inner workings of a product.

I’ll try to get the Cognitive Walkthrough thing sorted over the weekend. Over and out.

P.S. You didn’t think I’d forget, did you? Clip ahoy:

I know it has been videotaped with a camcorder off someones shabby telly and I don’t care. It’s still the best show ever!
