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.

Claims

1. A method comprising:

a) displaying a first side of a double-sided graphic image on a display device of a computer system; and

b) flipping the graphic image to display an opposing second side of the graphic image in response to a flip command provided by a flip gesture comprising a line having a loop, wherein the second side is displayed in substantially the same area of the display as the first side, wherein the first side is hidden when the second side is displayed.

2. A method for displaying a double-sided graphic image on a display device of a computer system, the method comprising:

a) recognizing a request to flip a first side of the graphic image, the request provided by a graphic gesture including a line having a loop;

b) flipping the graphic image and displaying an opposing second side, wherein the first and second sides are displayed is substantially a same area of the display device.

3. A method for displaying a double-sided graphic image on a display device of a computer system, the method comprising:

a) recognizing a request to flip a first side of the graphic image, wherein the request is provided by a graphic gesture substantially the same as a proofreader'"'"'s deletion mark and wherein the request is recognized only if entered by the user within a limited area of the display device, the limited area including a first area of the display device occupied by the graphic image and a second area of the display device forming a border extending from the first area;

b) flipping the graphic image and displaying an opposing second side, wherein the first and second sides are displayed is substantially a same area of the display device.

4. A method for displaying a double-sided graphic image on a display device of a computer system, the method comprising:

a) recognizing a request to flip a first side of the graphic image, wherein the request is provided by a graphic gesture complying with a set of pre-defined parameters including a location parameter and a gesture parameter, the gesture parameter specifying the type of gesture to be recognized, and wherein at least one of the pre-defined parameters is defined by the user;

b) flipping the graphic image and displaying an opposing second side, wherein the first and second sides are displayed is substantially a same area of the display device.
