XR Notification Display Control for View Obstruction Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increase in virtual objects corresponding to notifications in a virtual space displayed on XR glasses obstructs the user's field of view, deteriorating convenience.
Innovation Solution
A display control apparatus that includes an acquirer, generator, display controller, determiner, and movement controller to manage virtual objects based on distance from the user and recipient information, moving objects closer when within a predetermined distance and maintaining them stationary otherwise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If virtual objects corresponding to notifications are displayed in a virtual space, then information delivery is improved, but the field of view is obstructed and convenience deteriorates
Solution Approach 1:
The patent applies local quality by differentiating the display treatment of virtual objects based on their spatial relationship with the user. Virtual objects within a predetermined distance are moved closer to the user's position, while those beyond the distance remain at their original positions. This selective adjustment ensures that important notifications (those within distance) are prominently displayed without uniformly cluttering the entire virtual space, thus maintaining user convenience while effectively delivering notification information.
2Loss of information
If the number of virtual objects increases to reflect more notifications, then information completeness is improved, but field of view obstruction increases
Solution Approach 1:
The patent utilizes spatial dimensionality in the virtual space to manage the display of multiple virtual objects. By adjusting the position of virtual objects along the depth dimension (closer to or farther from the user), the system can display multiple notifications without them all occupying the same visual plane. This dimensional arrangement allows complete notification display while reducing field of view obstruction by distributing objects in three-dimensional space rather than crowding them in a two-dimensional field.

AI summary
A display control apparatus includes (i) an acquirer configured to acquire a notification, (ii) a generator configured to generate a virtual object corresponding to the notification, (iii) a display controller configured to display the virtual object in a virtual space in which a first user exists, (iv) a determiner configured to determine whether a distance between the virtual object and the first user is equal to or less than a predetermined distance in the virtual space, when the first user is included in recipient information, and (v) a movement controller configured to bring the virtual object closer to the first user, when a determination result of the determiner is affirmative.
