I'm a passionate reader, but I must admit that compared to e-books, I prefer physical books. Of course, we should not let our own prejudices hinder the popularity of e-books. After all, e-books will surely replace the current mainstream physical books in the near future. The reason we may be uncomfortable with e-books is that they lack the texture of physical books, and we are already accustomed to using physical books. Therefore, if we want e-books to become popular as soon as possible, I think they should be designed to provide a reading experience closer to that of physical books. This interactive e-book is a great design. Its biggest feature is that it has a rotatable corner. When we rotate the corner up, the e-book will turn to the next page; and when we rotate it down, it will go back to the previous page, which is very similar to the action of flipping through a physical book. And we can read comfortably on one plane. We can operate it with a positioning pen, and the color electronic paper display is compatible with touch, allowing direct interaction with our fingers.
