Tactile Music Learning Apparatus for Hearing-Impaired Pitch Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hearing-impaired individuals face difficulties in learning music using existing song practice systems that rely on sound and visual cues, as they struggle to match the pitch of songs with their own voices, limiting their ability to independently learn music.
Innovation Solution
A music learning apparatus and method that converts sound data into tactile data, synchronizing it with original music data to provide a tactile pattern through a tactile reproducing apparatus, allowing users to feel the pitch and rhythm through vibrations, enabling pitch matching and music practice without relying on auditory feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If sound and visual information are used for music learning, then music learning effectiveness is improved for hearing persons, but hearing-impaired persons cannot learn music because they cannot hear sound
Solution Approach 1:
The patent introduces tactile sensation as an intermediary medium between sound and the user. A tactile output device converts audio signals into tactile vibrations that can be felt through the skin, allowing hearing-impaired persons to perceive pitch and rhythm information that would normally be transmitted only through sound. This intermediary transformation enables music learning accessibility without relying on auditory perception.
Solution Approach 2:
The patent replaces the acoustic field (sound waves) with a mechanical field (tactile vibrations). By converting sound signals into tactile vibrations that can be felt through the skin, the system substitutes the auditory perception mechanism with a tactile perception mechanism, enabling hearing-impaired persons to perceive musical information through touch rather than sound.
2Adaptability or versatility
If tactile sensation is added to music learning system, then hearing-impaired persons can perceive pitch and rhythm, but system complexity increases
Solution Approach 1:
The patent makes the audio processing system multi-functional by adding tactile output capability to an existing music learning system. The same audio signal processing chain that generates sound output also generates tactile output signals, allowing a single system to serve both hearing persons (auditory feedback) and hearing-impaired persons (tactile feedback). This universal design approach increases adaptability while minimizing additional complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables hearing-impaired individuals to practice and learn music by sensing pitch and rhythm through tactile sensations, enhancing their ability to match pitches and enjoy independent music learning.
Implementation Method 1
The processor may generate the synchronized tactile pattern including a tactile pattern corresponding to the first tactile data to be reproduced at a first position of the tactile reproducing apparatus and a tactile pattern corresponding to the second tactile data to be reproduced at a second position of the tactile reproducing apparatus
Data Source
AI summary
A tactile music learning apparatus converts sound data of a user's voice corresponding to original music into first tactile data including tactile information, generates a synchronized tactile pattern by synchronizing the first tactile data with second tactile data including tactile information corresponding to sound data of the original music, and transfers the synchronized tactile pattern to a tactile reproducing apparatus to allow the tactile reproducing apparatus to reproduce the synchronized tactile pattern.
