Page Flip Effect Generation Using Lookup Table and Transparent Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices such as e-readers and mobile phones lack a realistic page flip effect when turning digital pages, making the experience less immersive, and existing software solutions require powerful processing units, increasing costs.
Innovation Solution
An electronic device with a processing unit, display unit, storage unit, and touch input unit that uses a flip-page operation table and effect parameters to generate a page flip effect by combining transparent effect pages with current and target pages, simulating the act of turning a physical page through touch input and sensor detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If software is introduced to generate a page flip effect, then the reading experience is improved, but the processing unit power and cost increase
Solution Approach 1:
The patent replaces complex software-based page flip effect generation with a simplified mechanism that uses pre-defined effect pages and basic processing operations. Instead of requiring powerful real-time rendering software, the system uses a lookup table approach where effect pages are selected and combined based on simple touch path analysis, dramatically reducing processing unit requirements while maintaining the visual page flip effect
Solution Approach 2:
The patent creates simplified copies of page flip effects using pre-rendered effect pages that represent different stages of page turning. These effect pages are stored in a lookup table and selectively combined with current and target pages to simulate the page flip effect, avoiding the need for complex real-time software rendering while achieving the desired visual experience
2Reliability
If software capable of generating page flip effect is introduced, then the visual realism is improved, but the device cost increases
Solution Approach 1:
The patent uses lightweight effect pages with simple transparency and positioning data instead of complex software components. These effect pages are stored as simple graphical elements in a lookup table and combined through basic overlay operations, creating a cost-effective solution that achieves visual realism without requiring expensive powerful processing units or complex software licenses
3Power
If direct page changing is used, then the processing requirement is low, but the reading immersion is poor
Solution Approach 1:
The patent introduces effect pages as intermediary elements between the current page and target page during page transitions. These effect pages contain transparency information and positioning data that create the visual illusion of page flipping, serving as a mediator that enhances reading immersion while requiring minimal processing power to select and combine with the actual pages

AI summary
A method for showing page flip effect when use electronic device enjoy electronic document, the method provides a flip-page operation table, the flip-page operation table defines relationships between flip effect parameters and lengths of a first touch path or a second touch path. The method comprising: receiving touch signals, determining the touch path and lengths of the touch path according the touch signals; determining which page will be brought into view (hereinafter target page) according to the touch path; obtaining a flip effect parameter when the touch path increase to lengths defined in flip effect table; combining a combined page according to the current page, the next page and the flip effect parameter. Present invention also providing an electronic device capable of executing said steps.
