However, there is very interesting thing for me that I would like to share and get your guy’s opinion. At page 36, the author argues that “Mechanical-Age representations degrade user interaction.” However, in my opinion, the evolution of technology changed that it may not be the case.
For example, a tangible human-computer interaction can be successful, if it resembles mechanical-age metaphor. An multi-touch interaction, which is common nowadays, is a good example. For example, there is a photo viewing application that adopts an coffee table metaphor. Many photos are displayed in the table. The user rotates or zoom-in using hand gestures. It is successful, because it uses an established metaphor, which don’t need to be learned by user.
Some could argue that this established metaphor is not mechanical-age representation. Though judging whether something is of mechanical-age oriented or not can be quite difficult, I will give another example. In the book, address book is given as an example of mechanical-age thing. However in my opinion the iPhone address app is adopting the physical address book representation in their side tap.
