Relative-Position Content Reproduction Without Real Map Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing services struggle to provide users with a consistent and immersive experience of content, such as images and audio sounds, across different locations, including places of residence and facilities, due to limitations in content arrangement and privacy concerns.
Innovation Solution
An information processing device and method that allows users to set and reproduce content based on relative positions between targets and devices, using a user interface and relative position detection methods, enabling content arrangement both indoors and outdoors without relying on precise map data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If content is arranged at specific places using map data, then content can be provided at outdoor locations, but privacy concerns arise and indoor arrangement becomes difficult
Solution Approach 1:
The patent replaces real-world map data with a virtual map that copies the essential spatial relationships. Targets are arranged on this virtual map rather than using actual geographic information, allowing content arrangement while protecting privacy by not exposing real location data.
Solution Approach 2:
The patent introduces a virtual map as an intermediary between the content arrangement system and the real world. This virtual representation mediates the spatial arrangement needs while preventing direct exposure of personal location information, thus resolving the privacy conflict.
2Adaptability or versatility
If creators arrange content for users, then content can be provided at visited places, but user experience at residence or facilities cannot be provided
Solution Approach 1:
The patent enables the content arrangement system to work universally across different environments (outdoor visited places, residence, facilities) by using relative position detection instead of location-specific map data. The same system architecture serves multiple functions and environments.
Solution Approach 2:
Instead of having creators arrange content based on user visit patterns, the patent allows users to independently arrange content themselves using the virtual map interface. This inversion of the arrangement process simplifies the system and enables flexible arrangement at any location.
3Measurement precision
If precise map data is used for content arrangement, then accurate content placement is achieved, but privacy is compromised and indoor use is limited
Solution Approach 1:
The patent creates a virtual map that copies the spatial structure needed for accurate content placement without using real geographic data. This virtual representation maintains measurement precision for relative positions while eliminating privacy concerns associated with actual map data.
4Productivity
If users can independently arrange content, then workload of creators is reduced, but system complexity increases
Solution Approach 1:
The patent enables users to perform content arrangement themselves through an intuitive virtual map interface. Users can drag and drop targets, set reproduction ranges, and arrange content independently without creator intervention,实现ing self-service content arrangement.

AI summary
Provided is an information processing device including a control unit that identifies, with at least one target, a content for each of the targets, and a reproduction range of the content set in advance, a relative position between the target and a device and compare the reproduction range with the relative position. The information processing device further includes a reproduction unit that reproduces the content on the basis of a result of the comparison between the reproduction range and the relative position.
