Virtual Space Cell Segmentation for Scalable Avatar Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing VR social networking services face delays and unnaturalness due to increased avatar information processing and transmission, which are not effectively addressed by existing techniques that prioritize transmission rates based on avatar proximity or image substitution.
Innovation Solution
An information processing device that divides a virtual space into reference, peripheral, and distant cells, using different levels of spatial information processing to reduce overall information load, including generating two-dimensional images for distant cells to minimize processing load.

Engineering Contradiction Analysis
1Adaptability or versatility
If the number of participating avatars is increased, then the VR social networking service becomes more popular and engaging, but the amount of avatar information increases resulting in increased information processing time and communication time
Solution Approach 1:
The virtual space is divided into multiple cells, and avatars are categorized into different groups based on their spatial relationships (first other avatars in the same cell, second other avatars in peripheral cells, third other avatars in distant cells). This segmentation allows differential information processing for different avatar groups, reducing overall processing time while maintaining quality for nearby avatars.
Solution Approach 2:
Different information processing qualities are applied to different spatial zones. First other avatars (same cell) receive full positional and action information, second other avatars (peripheral cells) receive simplified information, and third other avatars (distant cells) receive minimal information. This local quality differentiation reduces total information processing load while maintaining immersion for nearby users.
2Loss of time
If transmission rate for distant avatars is increased to reduce delay, then the delay in distant avatar is reduced, but the amount of information to be transmitted remains the same increasing overall data load
Solution Approach 1:
For third other avatars in distant cells, only essential minimal information is transmitted rather than complete positional and action information. This partial action approach reduces the quantity of transmitted information while still providing enough data to prevent noticeable delays, accepting that some detail is lost for distant users.
3Loss of time
If an image of an individual region in which a delay has occurred is substituted with a previous image, then a delay in displaying a high-resolution image is prevented, but an unnatural image may be obtained
Solution Approach 1:
Different image processing strategies are applied to different spatial regions. For first other avatars in the same cell, high-resolution real-time images are displayed. For second and third other avatars in peripheral and distant cells, simplified representations are used. This local quality differentiation prevents delays in critical regions while maintaining overall system performance.

AI summary
An information processing device (1) includes at least one processor, the at least one processor carrying out: an acquisition process for acquiring first spatial information indicating a reference cell serving as a cell in which a user is located in a virtual space, second spatial information indicating the virtual space located around the reference cell, and third spatial information indicating the virtual space located more distantly than a peripheral cell; and a spatial information process including a first process in which the first spatial information is used, a second process in which the second spatial information is used, and a third process in which the third spatial information is used and which involves a smaller processing load than the second process.
