Dynamic Playlist Generation via Proximity-Based Media Preference Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In group settings, it is challenging to play media that multiple people enjoy, as individual media libraries may contain content preferred by only a few, leading to dissatisfaction among attendees.
Innovation Solution
A system and method that determines when multiple mobile computing devices are in proximity, generating a dynamic playlist based on shared media preferences by analyzing historical usage data and metadata from multiple users' media libraries, ensuring that selected media items have a mutual interest score above a defined threshold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual media libraries are used for media playback in group settings, then each user's personal preferences are satisfied, but other attendees become dissatisfied due to lack of shared content
Solution Approach 1:
The patent combines multiple individual media libraries into a unified group media library by detecting proximity between devices and aggregating their media collections. This merging allows the system to access a broader pool of media content that reflects diverse user preferences, thereby satisfying more attendees in a group setting while maintaining ease of operation through automatic playlist generation.
Solution Approach 2:
The system dynamically adjusts the media playback configuration based on real-time conditions. When devices are detected to be in proximity, the system transitions from individual media library usage to a combined group media library mode. This dynamic adaptation enables the system to automatically switch between personal and shared playback modes, optimizing group enjoyment without requiring manual intervention.
2Ease of operation
If a dynamic playlist is generated by analyzing multiple users' media libraries and preferences, then group enjoyment increases, but system complexity increases due to proximity detection and preference analysis
Solution Approach 1:
The system performs self-service by automatically detecting device proximity, analyzing user preferences from media library metadata, and generating appropriate playlists without requiring manual user input. The proximity detection mechanism autonomously determines when to switch to group media library mode, and the preference analysis automatically identifies suitable media content, reducing the perceived complexity for end users while maintaining sophisticated functionality.
Solution Approach 2:
The patent introduces a server system that acts as an intermediary between multiple mobile computing devices. This intermediary handles the complex tasks of proximity detection coordination, preference analysis, and playlist generation, distributing the computational burden and simplifying the architecture. The server mediates the interaction between devices, managing the complexity of combining multiple media libraries while providing a simple user experience.
3Manufacturing precision
If media items are selected based on high mutual interest scores from shared preferences, then playlist quality improves, but processing time increases due to extensive analysis
Solution Approach 1:
The system performs preliminary actions by pre-analyzing media library metadata and establishing user preferences before the actual playback session. By examining media attributes, genres, and historical playback patterns in advance, the system builds a foundation of shared preferences that can be quickly queried during group sessions. This preliminary analysis reduces the processing time required during actual media selection while maintaining high playlist quality through pre-computed mutual interest scores.

AI summary
A method of managing electronic media items includes accessing first geographic information that indicates a first geographic location of a first device; accessing second geographic information that indicates a second geographic location of a second device; determining whether the first device and the second device are within a defined geographic proximity based on the first geographic location and the second geographic location; if the determination indicates that the first device and the second device are within the defined geographic proximity, generating at least one playlist of media items based on a set of media preferences shared between a first user of the first device and a second user of the second device; and sending the playlist to the first device such that the first user is able to select one or more of the media items on the playlist to be output by the first device.
