Annual World Usability Day

Yesterday was celebreated the 4th annual world usability day. In Uruguay it was in the ORT University  Artech and other companies from Uruguay were invited to participate in this event.

Yesterday while I was preparing my talk Fabian (a coworker and Mac fan) sent me the perfect sample for usability where the mental model of a 1 year old user match exactly with the program and hardware model

.

And additionally I found this sample where obviously the program model doesn't match the mental model  (From uselog)
