Reading on 3D desktop design

Principle used:

• Feedback & communication:

Feedback involves keeping users informed about what's happening by providing appropriate feedback & enabling communication with your app.
Two examples using in the work:
1. When a user clicks to the book, it shows visually that tell user the book has selected.
2. When a user clicks page by page on the right side, the book will response as thin to thick (left pages to right one)

• Perceived stability:

To provide an understandable, familiar, and predictable environment. To give users a visual sense of stability, the interface defines many standard graphical elements.
Some examples using in the work:
menu bar, search box, book outlook

• Metaphors:

Use metaphors that represent concrete, familiar ideas, and make the metaphors obvious, so that users can apply a set of expectations to the computer environment.
Examples using in the work:
the book design, the way to note/tag
