Method and apparatus for flipping a double-sided graphic image having different sized first and second sides

Abstract

Electronic paper which has two sides, reverse of one another, which can be flipped over in response to user generated flip commands is described. When a piece of electronic paper is flipped over, a number of transition views of the paper are generated to give the user the impression that the paper is actually being turned over to reveal a reverse side. Different information can be stored on either side, and the composition of either side can be linked so that changes made to the graphic information on one side affects the graphic information on the other side. In addition, when the amount of graphic information on the reverse side of the paper exceeds the amount of available space normally available on the reverse side when the paper is flipped over, approximately the same amount of space available on the top side, the reverse side is expanded to fit the quantity of information to be displayed on the reverse side. If the reverse side has been expanded, and the user instructs the page to flip back to the top side, the reverse side shrinks back to its original size and then flips back to the top side.
