Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing technologies struggle to seamlessly integrate and manage haptics data associated with moving image data, leading to discontinuous variations in tactile sensations, which can disrupt the user experience.
Innovation Solution
An image processing device and method that detect discontinuous variations in haptics data between adjacent sections in moving image data and modify the haptics data to suppress these discontinuities, ensuring a smoother and more consistent user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If haptics data is associated with moving image data to provide tactile sensation, then user experience is enhanced, but discontinuous variation in tactile sensation occurs during playback
Solution Approach 1:
The system performs preliminary detection of discontinuous variations in haptics data before playback occurs. By identifying sections where haptics data varies discontinuously between adjacent time sections, the system can prepare and apply smoothing corrections in advance, ensuring continuous tactile sensation during actual playback without interruptions or sudden changes.
Solution Approach 2:
The system continuously monitors and compares haptics data between adjacent time sections to detect discontinuities. When a discontinuous variation is detected, the system applies feedback-based smoothing to correct the haptics data, ensuring that the tactile sensation remains continuous and natural throughout the playback, thereby resolving the contradiction between enhanced user experience and stable tactile sensation continuity.
2Stability of the object's composition
If haptics data is modified to suppress discontinuous variation, then continuity of tactile sensation is improved, but processing complexity increases
Solution Approach 1:
The system divides the moving image data into discrete time sections and processes haptics data for each section independently. By segmenting the haptics data stream and comparing adjacent sections individually, the system can identify and correct discontinuities locally without requiring complex global processing, thus maintaining simplicity while achieving continuous tactile sensation.
Solution Approach 2:
The system modifies haptics data by adjusting specific parameters (such as vibration amplitude, frequency, or duration) in the affected time sections. Instead of fundamentally redesigning the haptics data structure, the system makes targeted parameter changes to suppress discontinuous variations, thereby improving continuity while minimizing processing complexity.

AI summary
An image processing device is provided that edits moving image data with which haptics data for eliciting haptic sensation is associated. The image processing apparatus detects whether or not first and second haptics data respectively associated with first and second sections that are adjacent in a time direction in edited moving image data vary discontinuously. If it is detected that the first and second haptics data vary discontinuously, the first and second haptics data are modified so as to suppress the discontinuous variation.
