Hoy leo en Smashing Magazine un interesante artículo acerca del diseño funcional, un extracto interesante de un par de puntos:

Obviously there are likely to be several audiences for any given product. Plenty of computer users have the knowledge, experience, and personality types to easily do whatever they choose to do on their computers. If you’re designing a niche product — a website for Linux users, for example — perhaps you can get away with directing yourself towards only one, narrow audience. In most cases, though, a product has to work equally for all its potential users if it’s to accomplish its goal.

Remember in the Bad Old Days of the Web, when you’d make a purchase online and the “Submit” button would say underneath something like:

Please press the “Submit” button only once. Pressing more than once will duplicate your purchase.

We’ve come a ways since then, but it’s surprising how many times you still come across a website feedback form that doesn’t tell you when your message has been sent, or a search form that doesn’t tell you that it’s working on your request.

This problem is by no means limited to the online world. How often do you double-check to see that your alarm clock is set to go off, and at the right time, before you can relax and go to sleep? Or maybe you’ve run into this problem: you hit “Program” on your CD player (assuming you still have one) and key in the tracks you want to hear, but aren’t sure whether to hit “Program” again or just hit “Play” — and if you hit the wrong one, whether your program will be lost and you’ll have to re-do it.
