Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a three-dimensional model of a virtual environment is displayed to show multiple user viewpoints and virtual objects, then the immersion and interactivity are improved, but the device complexity and computational resources required increase
Solution Approach 1:
The system creates simplified representations (avatars) of users and their viewpoints within the three-dimensional model. Instead of processing multiple complex camera feeds simultaneously, the system uses avatar-based representations that capture essential viewpoint information in a computationally efficient manner, allowing the display device to render the shared virtual environment with reduced computational overhead while maintaining immersion and interactivity.
Solution Approach 2:
The system introduces an intermediary processing layer that receives viewpoint data from multiple users, processes it through a coordination server, and transforms it into a unified three-dimensional model suitable for display. This intermediary layer abstracts the complexity of managing multiple viewpoints, allowing the display device to work with a pre-processed model rather than raw viewpoint data from all users.
2Adaptability or versatility
If the three-dimensional environment is displayed at full size for immersive viewing, then the user experience is improved, but the ability to show multiple users and objects simultaneously deteriorates
Solution Approach 1:
The system transitions from two-dimensional screen display to three-dimensional spatial representation, allowing multiple users and objects to be positioned in different spatial locations within the virtual environment. This dimensional expansion enables full-size immersive viewing while simultaneously accommodating multiple users and objects by distributing them across the three-dimensional space rather than competing for limited two-dimensional screen real estate.
Solution Approach 2:
The three-dimensional virtual environment is divided into distinct spatial regions where different users and objects can be positioned. Each user's viewpoint and associated objects occupy specific segments of the three-dimensional space, allowing the system to maintain full-size display quality while showing multiple users and objects simultaneously by allocating them to different spatial segments.
3Adaptability or versatility
If multiple user viewpoints are tracked and represented in the model, then the collaboration and interaction between users are improved, but the measurement precision and computational overhead increase
Solution Approach 1:
Instead of tracking and processing the complete high-precision viewpoint data from multiple users simultaneously, the system creates simplified avatar representations that capture the essential positional and orientational information needed for collaboration. These avatar copies maintain sufficient precision for collaborative interactions while reducing the computational overhead of processing multiple high-fidelity viewpoint streams.

AI summary
Some examples of the disclosure are directed to systems and methods for displaying three-dimensional models of virtual three-dimensional environments. In some examples, the three-dimensional model includes representations of the virtual object(s) included in the environment, a representation of a viewpoint of a user of the electronic device in the environment, and a representation of a viewpoint of a second user of a different electronic device in the environment. In some examples, in response to receiving an input requesting to display the virtual three-dimensional environment (e.g., at full size), the electronic device displays the virtual three-dimensional environment from the viewpoint of the user of the electronic device indicated in the model.
