Haptic Feature Extraction from Image Edges for Vibration Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image content technologies require modification and increased file size when adding high-quality haptic data, limiting the ability to effectively convey visual content through haptic sensations like vibration.
Innovation Solution
A method and apparatus that extract haptic features from image edges to generate vibration pattern signals, allowing for dynamic vibration generation based on user interaction, without modifying the image content, by segmenting image regions and using vibration pattern data to produce haptic feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If haptic data is added to image content to improve haptic quality, then the quality of haptic feedback is improved, but the file size of the image content increases
Solution Approach 1:
The patent extracts haptic features directly from the image content itself by analyzing edge information and texture patterns, rather than adding separate haptic data files. This extraction approach allows the system to generate haptic feedback from the existing image data, avoiding the need to store additional haptic information and thus preventing file size increase while maintaining haptic feedback quality
Solution Approach 2:
The patent creates a simplified representation of haptic information by copying only the essential edge and texture features from the image, rather than storing complete haptic data. This selective copying of critical visual features into haptic feature data structures enables efficient haptic feedback generation with minimal additional storage requirements
2Adaptability or versatility
If haptic data is pre-programmed into image content to enable haptic output, then haptic feedback can be generated, but the existing image content must be modified
Solution Approach 1:
The patent performs preliminary processing of image content by pre-defining haptic feature extraction rules and vibration pattern mappings that can be applied to any image without modifying the image itself. The system prepares extraction algorithms and pattern libraries in advance, enabling haptic feedback generation from standard image formats through direct analysis rather than modification
Solution Approach 2:
The patent creates a universal haptic feedback system that can process various types of image content (photos, graphics, videos) using the same edge detection and feature extraction algorithms. The vibration pattern database serves multiple functions by mapping different haptic features (edge density, texture, material properties) to appropriate vibration patterns, eliminating the need for separate haptic data for each image type
