Virtual Reality Object Sharing via Viewpoint Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In virtual reality, it is challenging for a first user to convey their viewing experience of an object to a second user in a way that the second user can witness the object from the same perspective, especially when they are in a different virtual location or time within the virtual reality space, leading to disorientation and disruption of the continuous viewing experience.
Innovation Solution
An apparatus and method that utilize first-user-viewing-experience information to render a 3-dimensional model of the object of interest in the second user's virtual reality space, synchronizing the point of view and appearance changes, allowing the second user to see the object as viewed by the first user, while maintaining continuity of their own virtual reality experience by isolating the object from background imagery and applying visual effects for distinction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the second user is shown the object from their current virtual location, then the second user can see the object, but the viewing perspective differs from the first user's experience, causing disorientation
Solution Approach 1:
The system creates a copy of the first user's viewing experience by capturing their point of view data (coordinates, orientation, timing) and reproducing it in the second user's virtual reality environment. This allows the second user to see exactly what the first user saw, maintaining perspective accuracy while preserving their own virtual location and experience continuity.
Solution Approach 2:
The system introduces an intermediary layer that translates the first user's viewing data into visual representations within the second user's virtual space. This intermediary mechanism reconciles the conflicting requirements by mediating between the original viewpoint and the second user's perspective, allowing both accuracy and continuity to coexist.
2Measurement precision
If the first user's viewpoint is reproduced in the second user's virtual space, then the viewing experience is accurate, but it disrupts the second user's continuous virtual reality experience
Solution Approach 1:
The system segments the virtual reality experience into distinct layers: the second user's base virtual environment and the overlaid first user's viewpoint representation. This segmentation allows the accurate reproduction of the first user's experience without disrupting the stability and continuity of the second user's primary virtual reality experience.
Solution Approach 2:
The system adds another dimension to the second user's virtual space by superimposing the first user's viewpoint data as an additional visual layer. This dimensional addition allows the first user's experience to be reproduced accurately while maintaining the second user's original virtual environment intact, preventing disruption to experience continuity.
3Manufacturing precision
If background imagery is removed to isolate the object, then the object is clearly visible, but the context and surroundings are lost
Solution Approach 1:
Instead of removing or altering the background imagery, the system creates a copy of the first user's complete viewpoint including both the object of interest and its surrounding context. This copying approach preserves all contextual information while still allowing the object to be clearly visible, as it appears exactly as it did in the original viewing experience.
Solution Approach 2:
The system performs preliminary capture of the complete viewing context before any display to the second user. By recording the full viewpoint data (coordinates, orientation, timing) in advance, the system ensures that contextual information is preserved and can be accurately reproduced, preventing any loss of context while maintaining clear object visibility.

AI summary
An apparatus configured to, in respect of first and second virtual reality content each configured to provide imagery for a respective first (206) and second (203) virtual reality space for viewing in virtual reality; and based on first-user-viewing-experience information defining an appearance of an object of interest (205) that appears in the first virtual reality content (206) as viewed, in virtual reality, by a first user (201), and defining a time-variant point of view from which the first user (201) viewed the object of interest (205); providing for display to a second user (202), the second user (202) provided with a virtual reality view of the second virtual reality content (203), of imagery of the object of interest (204) superimposed into the virtual reality space of the second virtual reality content (203) such that the second user (202) is able, while viewing the second virtual reality content (203), to witness the object of interest (204) as it was viewed by the first user.
