Page Difference Presentation for Simulated Texture Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current e-book technologies limit the selection of simulated textures and provide no emotional feedback based on user interactions, and haptic interaction feedback is only available during physical contact with a device.
Innovation Solution
A method and apparatus for differentially presenting a page by acquiring and updating page new-old parameters, including page new-old index, touch direction index, and touch strength level, based on user operations, allowing for dynamic and interactive simulation of page-turning effects without continuous physical contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If haptic interaction device is used to simulate textures, then realism of texture reproduction is improved, but interaction feedback is only available during body contact
Solution Approach 1:
The patent replaces the mechanical haptic feedback system with a visual simulation system that uses image processing and display technology. Instead of requiring physical contact with a haptic device, the system processes images to extract texture features and reproduces them visually on a display screen, allowing interaction feedback without body contact.
Solution Approach 2:
The patent creates a visual copy of the texture surface by extracting height information and friction coefficients from the original image, then reproducing these characteristics as visual patterns on the display. This allows the texture to be copied and presented without requiring the original physical object or haptic device.
2Device complexity
If limited textures are stored at back-end for user selection, then device complexity is reduced, but user experience and emotional feedback are limited
Solution Approach 1:
The patent changes the approach from storing multiple complete texture images to storing and processing a single reference image with extractable parameters. By extracting height maps, friction coefficients, and other texture parameters from the image data, the system can generate varied texture presentations through parameter manipulation rather than requiring multiple stored texture variants.
Solution Approach 2:
The patent makes a single image serve multiple functions by extracting various texture parameters (height, friction, roughness) that can be used to create different visual effects and interaction feedback. The same base image can produce different texture experiences through parameter extraction and processing, eliminating the need to store multiple separate texture files.
