Virtual page turn

Abstract

One or more pages are displayed on a display. A page-turning gesture is recognized. Responsive to such recognition, a virtual page turn that lifts a portion of the page is displayed on the display. One side of the lifted portion of the page is visible through the other side of the lifted portion of the page.

1 - 20 . (canceled) 
     
     
         21 . A system comprising:
 at least one processor; and   memory encoding computer executable instructions that, when executed by the at least one processor, perform a method comprising:
 displaying a virtual page on a display; 
 recognizing a page-turning gesture received via a touch interface; and 
 responsive to the page-turning gesture, displaying a virtual page turn progresses with the page-turning gesture as the page-turning gesture traverses the touch interface, wherein the virtual page turn lifts a portion of the virtual page. 
   
     
     
         22 . The system of  claim 21 , wherein the displaying the virtual page on the display comprises:
 determining a configuration of the display;   when the display is in a portrait configuration, displaying a single page from a virtual book; and   when the display is in a landscape configuration, at least two pages from the virtual book.   
     
     
         23 . The system of  claim 21 , wherein the virtual page turn progressively reveals a subsequent virtual page. 
     
     
         24 . The system of  claim 23 , wherein the virtual page turn progressively covers a preceding virtual page. 
     
     
         25 . The system of  claim 21 , wherein the virtual page turn further comprises progressively hiding first content on a front side of the lifted portion of the page while second content is progressively displayed on a back side of the virtual page. 
     
     
         26 . The system of  claim 21 , wherein the virtual page turn further comprises progressively revealing a second front side of a second page, the first backside of the first page having a transparency level that allows the first front side to be viewed through the back side of the first page. 
     
     
         27 . A digital reading device, comprising:
 a touch display;   a logic subsystem operatively coupled to the touch display; and   a data-holding subsystem holding instructions executable by the logic subsystem to:
 recognize a page-turning gesture; and 
 responsive to the page-turning gesture, displaying a virtual page turn progresses with the page-turning gesture as the page-turning gesture traverses the touch interface, wherein the virtual page turn lifts a portion of the virtual page. 
   
     
     
         28 . The digital reading device of  claim 27 , wherein the displaying the virtual page on the display comprises:
 determining a configuration of the display;   when the display is in a portrait configuration, displaying a single page from a virtual book; and   when the display is in a landscape configuration, at least two pages from the virtual book.   
     
     
         29 . The digital reading device of  claim 27 , wherein the virtual page turn further comprises progressively hiding first content on a front side of the lifted portion of the page while second content is progressively displayed on a back side of the virtual page. 
     
     
         30 . The digital reading device of  claim 27 , wherein the virtual page turn further comprises progressively revealing a second front side of a second page, the first backside of the first page having a transparency level that allows the first front side to be viewed through the back side of the first page. 
     
     
         31 . The digital reading device of  claim 27 , wherein the virtual page turn progressively reveals a subsequent virtual page. 
     
     
         32 . The digital reading device of  claim 27 , wherein the virtual page turn progressively conceals a preceding virtual page. 
     
     
         33 . The digital reading device of  claim 27 , wherein the method further comprises responsive to a reversal in the page-turning gesture, displaying a virtual page return that lowers the lifted portion of the page. 
     
     
         34 . The digital reading device of  claim 33 , wherein the virtual page return progressively conceals a subsequent page. 
     
     
         35 . The digital reading device of  claim 33 , wherein the virtual page return progressively uncurls the page. 
     
     
         36 . A method of animating a virtual page turn, comprising:
 displaying a virtual page on a display;   recognizing a page-turning gesture received via a touch interface; and   responsive to the page-turning gesture, displaying a virtual page turn progresses with the page-turning gesture as the page-turning gesture traverses the touch interface, wherein the virtual page turn lifts a portion of the virtual page.   
     
     
         37 . The method of  claim 36 , wherein the displaying the virtual page on the display comprises:
 determining a configuration of the display;   when the display is in a portrait configuration, displaying a single page from a virtual book; and   when the display is in a landscape configuration, at least two pages from the virtual book.   
     
     
         38 . The method of  claim 36 , wherein the virtual page turn further comprises progressively hiding first content on a front side of the lifted portion of the page while second content is progressively displayed on a back side of the virtual page. 
     
     
         39 . The method of  claim 36 , wherein the virtual page turn further comprises progressively revealing a second front side of a second page, the first backside of the first page having a transparency level that allows the first front side to be viewed through the back side of the first page. 
     
     
         40 . The method of  claim 36 , further comprising further comprises responsive to a reversal in the page-turning gesture, displaying a virtual page return that lowers the lifted portion of the page.
