Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If an object is displayed as a two-dimensional video, then the rendering simplicity is improved, but the three-dimensional visual effect deteriorates
Solution Approach 1:
The display area is segmented into multiple depth layers (first depth layer, second depth layer, third depth layer) with different z-coordinate ranges. Objects are assigned to different layers based on their depth information, allowing 2D video objects to be displayed on the first depth layer while 3D model objects are displayed on the second and third depth layers. This segmentation enables simultaneous display of both 2D and 3D content with distinct visual characteristics.
Solution Approach 2:
The patent introduces a depth dimension (z-coordinate) to the traditional two-dimensional display space by creating multiple depth layers. This allows objects to be positioned at different depths along the z-axis, enabling 3D visual effects while maintaining 2D display plane. The depth layers are arranged along the optical axis direction, creating a pseudo-3D space that enhances visual engagement without requiring full 3D display hardware.
2Adaptability or versatility
If an object is rendered as a three-dimensional model, then the visual engagement is improved, but the processing complexity worsens
Solution Approach 1:
The patent dynamically switches between 2D video rendering and 3D model rendering based on the object type and depth layer. The display control unit determines whether to display an object as 2D video or 3D model according to the depth layer and object characteristics. This dynamic adaptation allows the system to use computationally efficient 2D rendering for background objects while applying more intensive 3D rendering only where needed for foreground objects, optimizing processing resources.
Solution Approach 2:
Different rendering qualities are applied to different regions and objects based on their depth layer and importance. Foreground objects on higher depth layers receive 3D model rendering with higher visual quality, while background objects on lower depth layers use 2D video rendering. This local quality differentiation ensures visual engagement for important objects while maintaining overall processing efficiency.
3Device complexity
If multiple objects are displayed in a single depth layer, then the display simplicity is improved, but the depth perception worsens
Solution Approach 1:
The display is segmented into multiple depth layers along the optical axis, with each layer having a specific z-coordinate range. Objects are distributed across different layers based on their depth information, preserving spatial relationships and depth perception. This segmentation allows the system to maintain relatively simple 2D display planes while encoding depth information through layer assignment, preventing loss of depth information.

AI summary
For example, rendering is switchable. There is provided an information processing apparatus including: a first image processing unit that projects a predetermined object onto a two-dimensional plane in a virtual space; and a second image processing unit that renders a three-dimensional model related to a predetermined object at a location that is not the two-dimensional plane in the virtual space, in which at least a first rendering state by the first image processing unit and a second rendering state by the second image processing unit are switchable.
