At the beginning of 2010, I thought about the aging effect on the page or a product that was emotionally touching and easy to use for marking a clue on every page so that it will make users better usability using skeuomorphism. I was confident that people liked it because it remained an unconscious breadcrumb of using everyday products.
The color density of each mark would represent the frequency of usage. For example, the corner of every page of the book would have a mark of flipping over my fingers. And each photo that would have blurred or burned by sunlight represents how old the photos had been.
The reason why my idea was rejected is that it costs lots of money to realize because to show its aging effect, it needs a quite good resolution to represent. Second, it was really difficult to define how something was aged by some effect. There will be many causes that show age. And third, there was no strong evidence that people like to have aged products because every digital product and each element had everlasting quality and it's the attributes of the digital product itself.
But now I realized that the way that digital things show age is somewhat different from my ideas. The photo below looks so old based on the resolution of the image and the style of fashion. That's the way digital ages...
There would be some sentimental reason, but that's it, and no more... But I still miss some analogue aging effects on digital products. because still I live in a physical world and am a physical person, not a digital human.
