Signal Processing Apparatus for Aural Motion Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies do not allow users to aurally feel their own body motion, as they either require a sound source to represent motion or do not convert user motion into sound effectively.
Innovation Solution
A signal processing apparatus that attaches to a body or tool, using a microphone and sensor inputs to process aerodynamic and motion signals, amplifying and applying effects to generate sound signals that exaggerate body or tool motion, enabling users to feel their motion through sound.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If existing sound output technologies are used to represent motion, then sound can be generated, but the user cannot aurally feel the user motion itself
Solution Approach 1:
The patent replaces traditional mechanical sound generation systems with a signal processing system that directly converts motion sensor data into sound signals. The motion detection unit captures user motion, and the sound generation unit transforms this data into audible sound without requiring external sound sources or complex mechanical mechanisms, thereby preserving user motion information while simplifying the device structure.
Solution Approach 2:
The patent introduces a motion detection unit and sound generation unit as intermediary components between the user's body motion and the sound output. These units act as mediators that capture, process, and transform motion information into sound, enabling the user to aurally perceive their own motion without requiring external sound sources.
2Loss of information
If motion is converted to sound through existing technologies, then sound output is achieved, but the motion itself cannot be aurally presented
Solution Approach 1:
The patent substitutes complex sound source requirements with a direct motion-to-sound conversion system. The motion detection unit captures user motion data, and the sound generation unit processes this data into sound signals that directly represent the motion itself, eliminating the need for external sound sources and making the system easier to operate while preserving complete motion information.
Solution Approach 2:
The patent creates an acoustic copy of the user's motion by capturing motion data through the motion detection unit and transforming it into sound signals that replicate the characteristics of the original motion. This copying approach allows the motion itself to be aurally presented without requiring external sound sources, thereby preserving motion information while simplifying operation.
3Reliability
If a sound source is used to present motion, then sound output is achieved, but the user motion itself cannot be felt aurally
Solution Approach 1:
The patent replaces the need for external sound sources with an integrated motion-to-sound conversion system. The motion detection unit directly captures user motion, and the sound generation unit transforms this data into sound signals that accurately represent the motion itself. This substitution improves reliability by eliminating the disconnect between motion and sound while managing device complexity through integrated processing.
Solution Approach 2:
The patent creates a multi-functional system where the motion detection unit and sound generation unit work together to both detect motion and generate corresponding sound signals. This universal approach allows the system to preserve motion information accurately while maintaining manageable complexity through integrated functionality rather than separate sound source requirements.
