Multi-User AR Position Deviation Weight Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-user augmented reality environments, existing methods fail to address the issue of AR objects being displayed at different positions for each user, leading to a feeling of strangeness due to errors in self-position estimation and map creation, which affects the superimposition accuracy of virtual objects on real space.
Innovation Solution
An information processing device and method that acquires position information from multiple AR devices, calculates a deviation weight indicating the likelihood of position deviation, and adjusts the output method of AR objects to minimize the recognition of such deviations, ensuring a unified AR experience across users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If AR devices independently estimate self position and create maps using SLAM technology, then each user can experience augmented reality, but different errors occur in multiple AR devices causing AR objects to be displayed at different positions for each user
Solution Approach 1:
The patent combines the position estimation results from multiple AR devices by establishing a unified coordinate system that integrates the self-position information and map data from all devices. This merging process ensures that AR objects are displayed at consistent positions across all user views, resolving the contradiction between enabling multi-user AR experiences and maintaining position consistency.
Solution Approach 2:
The patent introduces a server as an intermediary that receives position information from multiple AR devices, calculates the appropriate transformation, and returns adjusted position data. This intermediary coordinates the position information from different devices, ensuring consistent AR object placement without requiring each device to independently handle the complexity of multi-device coordination.
2Ease of operation
If AR objects are displayed at different positions for each user due to estimation errors, then each user sees the AR object in their own coordinate system, but this creates a feeling of strangeness regarding augmented reality
Solution Approach 1:
The patent implements a feedback mechanism where position information from AR devices is continuously transmitted to the server, which calculates transformation results and returns adjusted position data. This closed-loop feedback ensures that AR objects are consistently positioned across all user views, eliminating the feeling of strangeness while maintaining ease of operation.
3Manufacturing precision
If the system adjusts AR object display to compensate for position deviations, then AR object position consistency is improved, but the complexity of position calculation and coordinate transformation increases
Solution Approach 1:
The patent uses a server as an intermediary to handle the complex position calculation and coordinate transformation tasks. Instead of requiring each AR device to independently manage complex multi-device coordination, the server centralizes these calculations, reducing the complexity burden on individual devices while maintaining position consistency.
Solution Approach 2:
The patent creates a universal coordinate system that serves all AR devices, providing a common reference frame for position calculations. This universal system simplifies the complexity by establishing a single coordinate transformation methodology that can be applied across all devices, rather than requiring device-specific complex calculations.

AI summary
Provided is an information processing device, and an information processing method for curbing occurrence of a feeling of strangeness in augmented reality in a use environment for a plurality of people. Position information indicating the self position of an AR device that outputs an AR object that is shown to the user as if the AR object existed in real space is acquired by the AR technology, and a deviation weight which is an evaluation value indicating how easily a plurality of users recognizes that an arrangement position of the AR object is deviated from each other on the basis of position information of a plurality of the AR devices and the arrangement position of the AR object. Then, the output method of the AR object is adjusted according to the deviation weight to make it difficult to recognize occurrence of the deviation.
