Dynamic Background Music Control via Track Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Video games face challenges in smoothly transitioning background music (BGM) based on game progress, often causing user discomfort due to abrupt changes.
Innovation Solution
A video game processing apparatus that dynamically controls BGM by updating music reproducing styles based on game point values, allowing for seamless transitions by combining multiple tracks and adjusting volume and tempo, and includes features for special modes and character appearance updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If BGM is switched by selectively reading out BGM in accordance with progress of the video game, then the BGM can be changed according to game status, but a sense of discomfort is given to the user before and after the BGM is switched
Solution Approach 1:
The patent applies dynamics by making the BGM reproducing style adjustable and changeable over time. The system dynamically transitions between different reproducing styles (e.g., from a first style to a second style) based on game progress, allowing smooth evolution of music characteristics rather than abrupt switches. This enables the BGM to adapt continuously to game status while maintaining user comfort through gradual transitions.
Solution Approach 2:
The patent utilizes parameter changes by modifying reproducing style parameters (such as tempo, volume, instrument selection, or melody variations) to transition between different BGM styles. Instead of abruptly switching between completely different tracks, the system changes parameters incrementally to transform the music from one style to another, thereby maintaining continuity and avoiding user discomfort while still adapting to game progress.
2Adaptability or versatility
If multiple tracks are combined to create plural kinds of reproducing styles, then the music can be reproduced in various forms, but the system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the music into multiple separate tracks (e.g., melody track, rhythm track, bass track). Each track can be independently controlled and combined in different reproducing styles. This segmentation allows the system to create variety by selectively activating or modifying individual tracks rather than managing entirely different music compositions, thereby reducing overall system complexity while maintaining versatility.
Solution Approach 2:
The patent utilizes merging by combining multiple segmented tracks to form complete music reproductions. Different tracks are merged in various configurations to create different reproducing styles (e.g., combining all tracks for full version, or selecting specific tracks for simplified versions). This merging approach allows versatile music reproduction from a unified structure, avoiding the need for separate complex systems for each style.
