Electronic Book Display with Rolling Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic books lack interactive features and fail to effectively display technical and scientific content, with limitations in replicating the classical book experience, including single-screen displays and limited navigation capabilities.
Innovation Solution
An interactive electronic book operating system that provides a classical book-like experience with two-page displays, dynamic indexing, customizable table of contents, bookmarks, and interactive features such as quizzes and tutoring, running on a Java Virtual Machine and supporting various computer platforms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If electronic books use single-screen flat displays, then device simplicity is maintained, but the classical book look and feel is lost
Solution Approach 1:
The patent introduces a scrolling mechanism that adds temporal dimension to the static display, creating a rolling image effect that simulates page turning while maintaining single-screen hardware simplicity
Solution Approach 2:
The display transitions from static flat images to dynamic rolling images that can scroll vertically to show multiple pages, adding motion and interactivity while keeping the physical device simple
2Device complexity
If electronic books display only one or two pages per screen, then device simplicity is maintained, but full page replication is lost
Solution Approach 1:
The patent adds vertical scrolling capability that extends the display in the time dimension, allowing multiple full pages to be accessed through rolling motion while maintaining the physical single-screen constraint
Solution Approach 2:
The content is divided into scrollable segments representing different pages, with the scrolling mechanism allowing users to navigate through these segments to access complete page content
3Device complexity
If electronic books lack interactive features, then device simplicity is maintained, but educational effectiveness for technical topics is reduced
Solution Approach 1:
The patent integrates multiple functions including scrolling display, bookmarking, and interactive elements into the electronic book system, making it versatile for both reading and educational purposes while maintaining hardware simplicity
Data Source
AI summary
A computing device may include a display, a memory to store electronic textbook data comprising a plurality of different images associated with at least one location within the electronic textbook data, a user input device, and a processor coupled to the display, the memory, and the user input device. The processor may be configured to display the electronic textbook data with a primary image from among the plurality of different images at the at least one location on the display, and selectively replace the primary image with at least one secondary image from among the plurality of different images at the at least one location on the display based upon the user input device.
