Hierarchy of Needs for Usability: Functional, Reliable, Usable, Pleasurable

There was a great article on Emotional Interface Design on Carsonified.com by Aaron Walter


The interfaces we design must first be functional – they need to solve a problem for us. Next, they need to be reliable – no fail whales please. Our interfaces need to be usable – easy to learn, easy to use, and easy to remember.

The piece we often overlook is the pleasure. It’s at the core of culinary arts, but we find it far too infrequently in the web apps and websites we use daily.

But what I liked best was this image:

Wrongful? Fines at Georgetown Township Public Library

I would like to know if there is anyone else out there who believes that they have been wrongfully fined by the Georgetown Township Public Library, particularly for "scratches" on DVD materials. I have received a $4 and a $6 fine on DVD's that were checked out from the public library in Jenison, and having a considerable number of CD's and DVD's myself, I consider it highly unlikely that the only ones that I have damaged belonged to the public library, after having been played once or twice. If this has happened to you, please comment here, and also make sure that you send a note to the GeorgeTown Township Supervisor, http://www.gtwp.com/board/tb.html Anyway, with Grandville Library so close, shouldn't we shut this one down anyway?

CFL Bulbs on sale at Meijer for $.99, but...

I was excited to see CFL bulbs on sale for .99 for up to 75w replacement bulbs. I had just purchased 4 of the GE Natural 60W Replacement bulbs for the new fixtures in my basement, so I bought some 75W Meijer bulbs to do side by side (you can exceed the watt recommendation in a fixture since it only uses 13-15W, right?) The 60 W GE Natural lights had so much brighter and better light than the "Soft Light" 75W bulbs. When I look into that room, it looks like the sun is shining in there. I have now become a lighting snob. Not everyone likes the bluish natural light, so please don't be discouraged from replacing your regular light bulbs with the .99 bulb, but try the expensive ones to, see if you're not happier. Who'da thunk I'd be excited about lighting?
