Shared-Space Music Selection from Intention-Respected Users
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing music selection systems fail to adequately consider the intentions of users when selecting musical pieces, leading to unsatisfactory music choices.
Innovation Solution
A music selection device that identifies an 'intention-respected' user by excluding 'intention-unrespected' users based on user state information and music-related data from mobile terminals, allowing for personalized music selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If music selection is made based on information from all users in the space, then the system considers all users' preferences, but the selection becomes conflicted and unsatisfactory when users have different intentions
Solution Approach 1:
The patent extracts and identifies the 'intention-respected user' from among multiple users in the space. By separating the intention-respected user from other users whose intentions are not to be respected, the system focuses music selection on the relevant user's preferences, eliminating conflicts caused by considering all users equally.
Solution Approach 2:
The patent segments the group of users into two categories: 'intention-respected users' whose preferences should guide music selection, and 'intention-unrespected users' whose preferences are excluded. This segmentation allows the system to process user information selectively, improving decision quality by focusing on the appropriate user segment.
2Measurement precision
If the system tries to identify the intention-respected user among multiple users, then music selection accuracy improves, but the complexity of user identification increases
Solution Approach 1:
The patent employs mobile terminals carried by users to automatically provide music-related information and intention data. The system leverages existing user devices and their capabilities to self-report preferences and intention status, eliminating the need for complex external identification hardware or manual surveys.
Solution Approach 2:
The patent utilizes the mobile terminal's existing functions (music playback, information storage, communication) to gather intention data. By making the mobile terminal serve multiple purposes - both as a personal music device and as an intention reporting tool - the system avoids adding separate identification infrastructure.

AI summary
A music selection device includes an identifying unit that identifies an user who is an intention-unrespected user whose intention is not required to be respected when a musical piece is selected, from among a plurality of users located in a predetermined space, and a music selection unit that selects a musical piece to be provided to the users located in the predetermined space based on music-related information of a mobile terminal carried by an intention-respected user excluding the intention-unrespected user from the plurality of users located in the predetermined space.
