Avatar Transparency Control for VR Immersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual reality systems face challenges in providing an immersive and clear virtual space experience when multiple users share the same virtual environment, as avatars can obstruct the view of 360-degree panorama videos and hinder communication due to opaque representations.
Innovation Solution
The system sets different transparency rates for parts of the avatars within the virtual space, with the first part (head and hand) being fully opaque and the second part (body and arm) being partially transparent, allowing for clearer recognition of facial expressions and gestures while maintaining a natural appearance and improving visibility of the environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If avatars are displayed as opaque in virtual reality, then user recognition and communication are improved, but the field of view and immersion in the virtual environment are obstructed
Solution Approach 1:
The patent applies local quality by differentiating transparency properties across different parts of the avatar. The head portion is rendered with higher opacity (more opaque) to ensure facial expressions and gestures are clearly recognizable for communication, while the body portion is rendered with lower opacity (more transparent) to reduce obstruction of the virtual environment. This spatial differentiation of transparency properties resolves the contradiction between avatar recognition and field of view.

3Loss of information
If avatars are displayed as fully opaque, then communication and recognition are enhanced, but immersion and natural appearance are reduced

AI summary
A method including defining a virtual space. The virtual space contains a first player character associated with a first user, a second player character associated with a second user, and virtual points of view for defining field-of-view images to be provided to a first HMD associated with the first user and to a second HMD associated with the second user. The method includes identifying first and second parts of the second player character. The method includes moving the first part in synchronization with a detected movement of the second user. The method includes displaying the second part in connection with a detected movement of the first part. The method includes setting a first transparency rate of the first part and a second transparency rate of the second part. A transparency rate of at least a portion of the second part is greater than the transparency rate of the first part.
