Acoustic-Tactile Conversion Using Spatial Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing acoustic-tactile conversion devices fail to accurately convert sound information from large spaces, such as performance halls, into tactile sensations, resulting in a disconnect between tactile and auditory experiences, and do not account for the user's location within the space.
Innovation Solution
A system and method that utilize spatial information to convert acoustic information into tactile information, including an acoustic-tactile conversion device that generates spatial tactile values based on user location, and tactile reproducing devices that provide tailored tactile stimulation, incorporating feedback for enhanced realism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If acoustic information is converted into tactile information without considering spatial information, then the conversion process is simple, but the tactile experience lacks realism and homogeneity between tactile and auditory senses is poor
Solution Approach 1:
The patent introduces spatial dimension to the acoustic-tactile conversion process by incorporating spatial information (position, orientation, distance) as an additional dimension of data processing. The system converts acoustic information into tactile information while maintaining spatial relationships, transforming a 1D/2D conversion problem into a 3D spatial-aware conversion problem, thereby enhancing realism without oversimplifying the process
Solution Approach 2:
The patent applies local quality by generating different tactile signals based on the user's specific location and spatial characteristics. Instead of using a uniform conversion approach, the system tailors the tactile output to match the local acoustic environment at the user's position, creating homogeneous experiences between tactile and auditory senses for each user's specific spatial context
2Reliability
If tactile reproduction does not reflect user location and spatial characteristics, then the system is easier to implement, but there is a sense of heterogeneity between tactile and auditory sense
Solution Approach 1:
The patent incorporates feedback mechanisms where the system receives spatial information about the user's location and uses this feedback to adjust the tactile conversion process. The system continuously monitors spatial characteristics and adjusts the tactile output accordingly, creating a closed-loop system that enhances realism by ensuring the tactile experience matches the user's actual spatial context
Solution Approach 2:
The patent implements dynamics by making the tactile conversion process adaptive rather than static. The system dynamically adjusts conversion parameters based on real-time spatial information, user location, and acoustic environment. This dynamic adaptation allows the system to maintain high realism across different spatial conditions without requiring a completely complex redesign for each scenario
3Ease of operation
If acoustic-tactile conversion does not consider spatial information, then processing is faster and simpler, but the converted tactile sense cannot harmonize with sight, hearing, and spatial sense
Solution Approach 1:
The patent merges multiple types of information processing by combining acoustic information conversion with spatial information processing into a unified system. Instead of treating tactile conversion and spatial processing as separate operations, the system integrates them to simultaneously generate tactile output that reflects both acoustic and spatial characteristics, achieving sensory harmony across multiple modalities

AI summary
Disclosed are a system and method for reproducing tactile content using spatial information, which enhances a users tactile sense of music by converting a sound of music played in a space into tactile sense in real time without any sense of difference between tactile and auditory sense and automatically correcting tactile information by reflecting a user location and spatial characteristics so that performance or image information may be realized as tactile content using spatial information and the user location.
