Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Realistic page-turning animations on digital reading devices are often computationally demanding, exceeding the processing ability of many devices, resulting in unrealistic implementations that fail to accurately account for real-time user interactions.
Innovation Solution
A method that generates a virtual cylinder based on page turn input information, projects the digital content page onto the cylinder, and renders it on the device's display, allowing for textured page rendering responsive to the projection, enhancing the realism of page-turning animations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If realistic page-turning animations are implemented using traditional methods, then the visual realism is improved, but the computational demand exceeds the processing ability of many digital reading devices
Solution Approach 1:
The patent segments the page-turning animation into discrete cylindrical segments that can be independently rendered and textured. This allows the complex animation to be broken down into manageable computational units that can be processed efficiently on resource-constrained devices while maintaining visual realism.
Solution Approach 2:
The patent transitions from traditional 2D page representation to a 3D cylindrical model for page-turning animation. This dimensional change enables more realistic curvature and folding effects while providing a mathematical framework that can be efficiently rendered through projection techniques suitable for mobile devices.
2Ease of operation
If traditional page-turning animation methods are used, then the implementation is simpler, but the animations fail to accurately account for real-time user interactions
Solution Approach 1:
The patent incorporates feedback mechanisms that continuously monitor user interaction parameters (such as finger position, swipe velocity, and pressure) and dynamically adjust the cylinder generation and page projection in real-time. This ensures that the animation accurately reflects user intentions while maintaining responsive performance.
Solution Approach 2:
The patent implements dynamic parameters for the virtual cylinder including variable radius, position, and rotation angle that respond to user interaction. The cylinder's geometric properties are continuously adjusted based on real-time input data, enabling realistic page-turning behavior that adapts to user actions without requiring complex pre-computed animation sequences.

AI summary
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.
