Haptic Effect Parameter Modification for Slow Motion Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems inaccurately render haptic effects in slow motion, failing to synchronize these effects with corresponding visual and auditory cues, leading to a disjointed user experience in interactive devices.
Innovation Solution
The system dynamically calculates and modifies haptic parameters such as magnitude, frequency, and duration of haptic effects based on an analysis of the media stream, ensuring accurate rendering of haptic effects in slow motion by adjusting these parameters to match the slowed playback rate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If haptic effects are rendered during slow motion playback, then the duration of haptic effects is extended to match the slowed playback rate, but the synchronization accuracy between haptic effects and media cues deteriorates
Solution Approach 1:
The system dynamically adjusts haptic parameters (magnitude, frequency, duration) based on the playback rate. During slow motion playback, the haptic duration is extended proportionally to match the slowed media playback, while the magnitude and frequency are modified to maintain perceptual accuracy. This parameter adaptation resolves the contradiction by allowing extended duration without sacrificing synchronization quality.
Solution Approach 2:
The haptic rendering system transitions from static parameter rendering to dynamic parameter adjustment based on real-time playback rate analysis. The system continuously monitors media playback speed and adapts haptic effect parameters accordingly, enabling accurate synchronization across varying playback rates including slow motion, fast forward, and normal speed.
2Measurement precision
If haptic parameters are dynamically calculated based on media stream analysis, then the synchronization between haptic effects and media cues is improved, but the computational complexity increases
Solution Approach 1:
The system performs preliminary analysis of the media stream to identify key temporal markers and cue points before rendering haptic effects. By pre-processing the media data to extract timing information and event markers, the system reduces the computational burden during actual haptic rendering while maintaining high synchronization accuracy.
Solution Approach 2:
The system introduces an intermediary processing layer that analyzes media streams and translates them into simplified haptic parameter instructions. This intermediary module acts as a bridge between complex media analysis and straightforward haptic rendering, reducing overall system complexity while preserving synchronization precision.

AI summary
Systems and methods for generating and modifying a haptic effect are provided. Haptic effects are rendered in slow motion by modifying the various parameters associated with each haptic effect of a haptic effect sequence. For example, the magnitude, frequency, and/or duration of each haptic effect may be altered to accurately convey the haptic effect sequence in slow motion.
