Animated page turning
First Claim
1. A method of showing a page turn animation in connection with a digital content page displayed by a digital reading device display, comprising:
- receiving page turn input information indicating a location on the display from which a page turn input is received, wherein the page turn input information further indicates a direction and speed of the page turn input on the device display;
selecting, based on the speed of the page turn input, a pre-determined speed that represents the speed of the page turn input;
generating a virtual cylinder having a location and radius that are determined based at least in part on the direction of the page turn input that is indicated by the page turn input information and the pre-determined speed, the virtual cylinder configured to move from a right edge of the digital content page to a left edge of the digital content page during the page turn animation, wherein the radius is based on the location of the virtual cylinder on the digital content page such that the radius increases from a smallest radius associated with a first location of the virtual cylinder at the right edge of the digital content page to a largest radius associated with a second location of the virtual cylinder at the left edge of the digital content page, the virtual cylinder being generated by recomputing the location and radius of the virtual cylinder a quantity of times that is determined based on the pre-determined speed;
projecting the digital content page onto the cylinder;
rendering the generated cylinder on the display of the digital reading device; and
texturing the page onto the rendered cylinder responsive to the projection.

Abstract
A digital reading device includes reader functionality and displays a page turn animation. The digital reading device includes a display displaying a digital content page. The display may include touch-sensitive functionality. Page turn input information including location information is received at the digital reading device. A virtual cylinder is generated based on the information. A corresponding cylinder surface location is determined for each of one or more page locations. The generated cylinder is rendered on the display and the digital content of each of the one or more page locations is textured on the rendered cylinder at the corresponding cylinder surface locations. The digital reading device adaptively tracks the movement of a page input on the display and produces a page turn animation that responds to the movement of the page turn input.

8. A non-transitory computer-readable storage medium storing executable computer program instructions for showing a page turn animation in connection with a digital content page displayed by a digital reading device display, the instructions comprising instructions for:
-
receiving page turn input information indicating a location on the display from which a page turn input is received, wherein the page turn input information further indicates a direction and speed of the page turn input on the device display; selecting, based on the speed of the page turn input, a pre-determined speed that represents the speed of the page turn input; generating a virtual cylinder having a location and radius that are determined based at least in part on the direction of the page turn input that is indicated by the page turn input information and the pre-determined speed, the virtual cylinder configured to move from a right edge of the digital content page to a left edge of the digital content page during the page turn animation, wherein the radius is based on the location of the virtual cylinder on the digital content page such that the radius increases from a smallest radius associated with a first location of the virtual cylinder at the right edge of the digital content page to a largest radius associated with a second location of the virtual cylinder at the left edge of the digital content page, the virtual cylinder being generated by recomputing the location and radius of the virtual cylinder a quantity of times determined based on the pre-determined speed; projecting the digital content page onto the cylinder; rendering the generated cylinder on the display of the digital reading device; and texturing the page onto the rendered cylinder responsive to the projection. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A digital reading device for showing a page turn animation in connection with a digital content page displayed by the digital reading device, comprising:
-
a non-transitory computer-readable storage medium storing executable computer program instructions comprising instructions for; receiving page turn input information indicating a location on the display from which a page turn input is received, wherein the page turn input information further indicates a direction and speed of the page turn input on the device display; selecting, based on the speed of the page turn input, a pre-determined speed that represents the speed of the page turn input; generating a virtual cylinder having a location and radius that are determined based at least in part on the direction of the page turn input that is indicated by the page turn input information and the pre-determined speed, the virtual cylinder configured to move from a right edge of the digital content page to a left edge of the digital content page during the page turn animation, wherein the radius is based on the location of the virtual cylinder on the digital content page such that the radius increases from a smallest radius associated with a first location of the virtual cylinder at the right edge of the digital content page to a largest radius associated with a second location of the virtual cylinder at the left edge of the digital content page, the virtual cylinder being generated by recomputing the location and radius of the virtual cylinder a quantity of times determined based on the pre-determined speed; projecting the digital content page onto the cylinder; rendering the generated cylinder on the display of the digital reading device; and texturing the page onto the rendered cylinder responsive to the projection; and a processor for executing the computer program instructions. - View Dependent Claims (16, 17, 18, 19, 20, 21)
