XR Display Collision Alerts Using User-Specific Notification Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing XR technologies fail to accurately notify users of potential collisions when viewing another user's XR image, as users may not recognize the danger due to being immersed in the XR experience.
Innovation Solution
An information processing system that acquires images from both users' displays, determines the possibility of collision, and controls the display devices to notify users using distinct alert forms based on their individual collision risks, differentiating between the users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single notification form is used for all users, then the system is simple to operate, but users cannot correctly recognize their own collision danger when viewing another user's XR image
Solution Approach 1:
The notification system is segmented into distinct notification forms: first notification form for the first user (image acquirer) and second notification form for the second user (image viewer). This segmentation allows each user type to receive appropriately tailored notifications, enabling accurate collision risk recognition for both the user whose image is being viewed and the user whose image is being viewed, while maintaining clear operational distinctions.
2Adaptability or versatility
If XR images are shared between users, then multiple users can view and discuss the same XR content, but the risk of collision increases for the viewing user
Solution Approach 1:
The system performs preliminary collision risk assessment by acquiring attitude information of the second display device before the second user can move into a dangerous position. By detecting the attitude (orientation, position) of the second display device and predicting potential collision paths in advance, the system issues warnings before the harmful collision event occurs, allowing the second user to take preventive action while maintaining the beneficial XR sharing experience.
3Reliability
If collision warnings are displayed on the XR display, then users are alerted to potential dangers, but users immersed in XR experience may not correctly recognize the warning is for themselves
Solution Approach 1:
Different notification forms are applied to different users based on their role in the XR sharing system. The first notification form is specifically designed for the first user (whose image is being acquired), while the second notification form is specifically designed for the second user (who is viewing the first user's image). This localized differentiation ensures that each user receives warnings tailored to their specific situation, eliminating confusion about whether the warning applies to them personally.

AI summary
An information processing device performs acquisition processing to acquire a first image based on an attitude of a first display used by a first user, performs determination processing to determine a possibility of collision of a second user, performs selection processing to select a display mode of a second display, and controls the second display device used by the second user. The second display device displays the first image when a first display mode is selected in the selection processing, and displays a second image based on an attitude of the second display device when a second display mode is selected in the selection processing. When the possibility of collision of the second user is high, the possibility of collision of the second user is notified to the second user using a notification form that is different in accordance with the display mode selected in the selection processing.
