Vibration Motor Frequency Encoding for Musical Tone Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional game systems that provide vibration effects do not consider sound integration, limiting the ability to synchronize vibrations with musical tones.
Innovation Solution
An information processing system that includes a first and second information processing apparatus, where the first apparatus generates and encodes frequency instruction data based on a musical scale, and the second apparatus decodes and vibrates a motor based on this data, using specific encoding and decoding expressions to synchronize vibration with musical notes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional vibration control systems are used, then vibration effects can be provided, but sound synchronization capability is lost
Solution Approach 1:
The patent changes the parameter representation from raw frequency values to encoded values based on musical scale notes. The encoding formula transforms frequency f into an encoded value using the relationship between musical notes and frequencies, allowing the vibration motor to be controlled through musical note references rather than raw frequency data, thereby enabling sound synchronization while managing complexity through mathematical transformation
Solution Approach 2:
The patent introduces an intermediary encoding/decoding mechanism that acts as a mediator between the vibration control system and the audio system. This intermediary layer translates between vibration frequency commands and musical note frequencies, enabling coordination between haptic and auditory outputs without requiring direct integration of complex control algorithms in both systems
2Measurement precision
If frequency instruction data is transmitted without encoding, then transmission is simple, but data precision and synchronization accuracy deteriorate
Solution Approach 1:
The patent transforms the frequency parameter into an encoded parameter based on musical scale relationships. By representing frequencies as encoded values corresponding to musical notes rather than raw frequency numbers, the system achieves more precise synchronization with audio while the encoding complexity is managed through established mathematical relationships between musical intervals and frequencies
3Adaptability or versatility
If vibration frequency is controlled independently of musical scale, then vibration control is simple, but integration with audio feedback is lost
Solution Approach 1:
The patent makes the vibration control system universal by enabling it to operate in conjunction with audio feedback through the musical scale encoding. The same encoding mechanism that handles vibration frequency control also facilitates synchronization with audio notes, allowing the system to serve both vibration control and audio integration functions through a unified approach
