Ink Annotation Sharing Across E-Book Terminals With Adaptive Rendering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to effectively share ink annotations, such as handwritten notes and illustrations, across different electronic book terminals with varying display settings and pen compatibility, preserving the creative value and pen-based input.
Innovation Solution
A method and system for sharing ink annotations that include stroke data sets and metadata, enabling identification and display of annotations on different terminals by using user and book identifiers, and applying rendering effects to mimic pen-based input, even with differing display settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If ink annotations are shared across different electronic book terminals, then accessibility and collaboration are improved, but compatibility issues arise due to varying display settings and pen types
Solution Approach 1:
The patent introduces an intermediary system that acts as a mediator between different electronic book terminals and pen devices. This intermediary layer translates and adapts annotation data from one terminal's coordinate system and display settings to another terminal's specifications, enabling compatible annotation sharing without direct dependency between different devices.
Solution Approach 2:
The patent applies parameter changes by transforming annotation data according to different display settings such as resolution, font size, and column configuration. The system adjusts parameters like coordinate scaling, stroke width, and positioning to match the target terminal's display characteristics, ensuring consistent visual appearance across diverse devices.
2Ease of operation
If display settings are customized for each terminal, then user experience is improved, but annotation consistency across terminals deteriorates
Solution Approach 1:
The patent implements dynamics by making the annotation rendering adaptive rather than static. The annotation system dynamically adjusts its presentation based on the terminal's display settings while maintaining the original annotation's intent and position. This dynamic adaptation allows consistent user experience across customized displays without compromising annotation stability.
3Ease of manufacture
If pen-based input is preserved for creative annotations, then authenticity and creativity are improved, but compatibility with different pen types deteriorates
Solution Approach 1:
The patent applies universality by creating a unified annotation system that can handle multiple pen types and input methods through a single interface. The system abstracts away the specific pen characteristics and provides universal functionality for receiving, processing, and sharing annotations regardless of the pen type used, thereby preserving creative value while achieving broad compatibility.
Data Source
AI summary
An ink annotation sharing method is carried out in a system, which includes a first terminal operable by a first user, a second terminal operable by a second user, and an ink annotation sharing system. The ink annotation includes a stroke data set indicating an annotation added to an electronic book and metadata. The metadata includes a user identifier, a book identifier, and place data indicating a place of the annotation. The method includes transmitting, by the first terminal, the ink annotation generated by an operation of the first user, to the ink annotation sharing system; identifying, by the ink annotation sharing system, the second user who is a member of a group that relates to the electronic book and that is configured by the first user based on the user and book identifier values; and supplying, by the ink annotation sharing system, the ink annotation to the second terminal.
