Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users in virtual environments must manually select and arrange music playlists, which is tedious and results in static playlists that do not adapt to changing situational contexts, leading to user fatigue from repetitive music.

Innovation Solution

A method to generate dynamic playlists based on user interactions and situational characteristics within the virtual environment, using stored music preference data indexed by song properties and situational factors like activity, location, and mood, to provide adaptive music playback.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If users manually select and arrange music playlists, then users have control over music selection, but the process is tedious and results in static playlists that do not adapt to changing situational contexts

Engineering Contradiction:

Improveplaylist adaptabilityVSAvoidmanual playlist creation

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system automatically generates and updates playlists by monitoring user interactions with virtual objects and determining situational context, eliminating the need for manual playlist creation and updating while adapting to changing user situations

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system continuously monitors user interactions with virtual objects and uses this feedback to dynamically adjust playlist content, creating playlists that adapt to changing situational contexts without manual intervention

Inventive Principle:

Principle #23Feedback

2Ease of operation

If static playlists are used, then playlist structure is simple, but user fatigue occurs from repetitive music that does not match changing situations

Engineering Contradiction:

Improveplaylist managementVSAvoidsituational adaptation

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system transitions from static playlists to dynamic playlists that automatically update based on real-time monitoring of user interactions and situational context, allowing the music selection to adapt to changing user situations without increasing operational complexity

Inventive Principle:

Principle #15Dynamics

3Adaptability or versatility

If automated playlist generation is implemented, then playlist adaptability to situational context is improved, but system complexity increases

Engineering Contradiction:

Improvecontext-aware playlist generationVSAvoidplaylist generation system

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system uses a multi-functional approach where the virtual object interaction monitoring system serves dual purposes: tracking user gameplay behavior and providing contextual data for playlist generation, thereby achieving context-aware playlists without adding separate dedicated systems

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Embodiments of the invention provide techniques for generating song playlists for use in an immersive virtual environment. Generally, playlists may be generated based on stored music preference data. The music preference data may be generated by storing user interactions with specific songs. The user interactions may be associated with characteristics of the user's situational context within the virtual world. The music preference data may be indexed by song name, and/or by musical properties. Subsequently, the music preference data may be used to generate a playlist adapted to the user's current situation within the virtual world.
