Abstract

One or more pages are displayed on a touch display. A page-turning gesture directed to a displayed page is recognized. Responsive to such recognition, a virtual page turn is displayed on the touch display. The virtual page turn actively follows the page-turning gesture. The virtual page turn curls a lifted portion of the page to progressively reveal a back side of the page while progressively revealing a front side of a subsequent page. A lifted portion of the page is given an increased transparency that allows the back side of the page to be viewed through the front side of the page. A page-flipping gesture quickly flips two or more pages.

Claims

1. A digital reading device, comprising:

a first touch display region;

a second touch display region;

a logic subsystem operatively coupled to the first touch display region and the second touch display region; and

a data-holding subsystem holding instructions executable by the logic subsystem to;

display a back side of a first page on the first touch display region and a front side of a second page on the second touch display region;

recognize a page-turning gesture directed to an outer corner of the second page;

display, responsive to the page-turning gesture, a virtual page turn that actively follows the page-turning gesture, the virtual page turn curling a lifted portion of the second page to progressively reveal a back side of the second page while progressively revealing a front side of a third page and while progressively covering the back side of the first page;

recognize a page-flipping gesture directed along an outer edge of the second touch display region; and

display, responsive to advancement of the page-flipping gesture, a virtual page flip in which pages quickly flip from the second touch display region to the first touch display region.

2. The digital reading device of claim 1, were the outer corner of the second page tracks an object performing the page-turning gesture as the object moves across the first touch display region and the second touch display region.

3. The digital reading device of claim 1, where the data-holding subsystem further holds instructions executable by the logic subsystem to:

recognize a reversal in the page-turning gesture; and

responsive to the reversal in the page-turning gesture, display a virtual page return that actively follows the page-turning gesture, the virtual page return uncurling a lifted portion of the second page to progressively conceal a back side of the second page while progressively concealing a front side of the third page.

4. The digital reading device of claim 1, where the data-holding subsystem further holds instructions executable by the logic subsystem to:

recognize a shortcut in the page-turning gesture; and

responsive to the shortcut in the page-turning gesture, accelerating the virtual page turn ahead of an object performing the page-turning gesture to quickly complete the virtual page turn.

5. The digital reading device of claim 1, where the first touch display region is located on a first touch display and the second touch display region is located on a second touch display, and where the digital reading device further comprises a spine joint foldably connecting the first touch display to the second touch display.

6. 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;

display a front side of a page on the touch display;

recognize a page-turning gesture directed to the page on the touch display; and

display a virtual page turn that actively follows the page-turning gesture, the virtual page turn curling a lifted portion of the page to progressively reveal a back side of the page while progressively revealing a front side of a subsequent page, the lifted portion of the page having an increased transparency that allows the back side of the page to be viewed through the front side of the page.

7. The digital reading device of claim 6, were a corner of the page tracks an object performing the page-turning gesture as the object moves across the touch display.

8. The digital reading device of claim 6, where the virtual page turn further curls the lifted portion of the page to progressively cover a back side of an opposing page.

9. The digital reading device of claim 8, where the lifted portion of the page progressively covers the back side of the opposing page responsive to an object performing the page-turning gesture moving over a portion of the touch display that was displaying the opposing page.

10. The digital reading device of claim 8, where the virtual page turn substantially fully covers a back side of the opposing page and substantially fully reveals the subsequent page if the page-turning gesture advances to completion.

11. The digital reading device of claim 6, where the data-holding subsystem further holds instructions executable by the logic subsystem to:

recognize a reversal in the page-turning gesture; and

responsive to the reversal in the page-turning gesture, display a virtual page return that actively follows the page-turning gesture, the virtual page return uncurling a lifted portion of the page to progressively conceal a back side of the page while progressively concealing a front side of the subsequent page.

12. The digital reading device of claim 6, where the data-holding subsystem further holds instructions executable by the logic subsystem to:

recognize a page-flipping gesture directed along an outer edge of the touch display; and

display, responsive to advancement of the page-flipping gesture, an accelerated flipping of pages.

13. The digital reading device of claim 6, where the data-holding subsystem further holds instructions executable by the logic subsystem to:

recognize a shortcut in the page-turning gesture; and

responsive to the shortcut in the page-turning gesture, accelerating the virtual page turn ahead of an object performing the page-turning gesture to quickly complete the virtual page turn.

14. The digital reading device of claim 6, where the increased transparency of the lifted portion of the page further allows the front side of the page to be viewed through the back side of the page.

15. A method of operating a computing device having a touch display with a first touch display region and a second touch display region, the method comprising:

displaying a back side of a first page on the first touch display region and a front side of a second page on the second touch display region;

recognizing a page-turning gesture directed to an outer corner of the second page; and

displaying, responsive to the page-turning gesture, a virtual page turn that actively follows the page-turning gesture, the virtual page turn curling a lifted portion of the second page to progressively reveal a back side of the second page while progressively revealing a front side of a third page and while progressively covering the back side of the first page, the lifted portion of the second page having an increased transparency that allows the back side of the second page to be viewed through the front side of the second page.

16. The method of claim 15, were the outer corner of the second page tracks an object performing the page-turning gesture as the object moves across the first touch display region and the second touch display region.

17. The method of claim 15, where the lifted portion of the second page progressively covers the back side of the first page responsive to an object performing the page-turning gesture moving over a portion of the second touch display region that was displaying the first page.

18. The method of claim 15, where the virtual page turn substantially fully covers a back side of the first page with the second page and substantially fully reveals the third page if the page-turning gesture advances to completion.

19. The method of claim 15, further comprising:

recognizing a reversal in the page-turning gesture; and

responsive to the reversal in the page-turning gesture, displaying a virtual page return that actively follows the page-turning gesture, the virtual page return uncurling a lifted portion of the second page to progressively conceal a back side of the second page while progressively concealing a front side of the third page.

20. The method of claim 15, further comprising:

recognizing a shortcut in the page-turning gesture; and

responsive to the shortcut in the page-turning gesture, accelerating the virtual page turn ahead of an object performing the page-turning gesture to quickly complete the virtual page turn.
