Virtual Space Field of View Rotation for Object Anchoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional virtual space presentation systems fail to simulate real-world rotation effectively, as objects in the virtual space rotate with the device, disrupting the user's experience by not anchoring the virtual space to the real world.
Innovation Solution
A system that dynamically adjusts the field of view in a virtual space based on the device's position, maintaining object positions fixed while simulating rotation about an axis perpendicular to the display, allowing the view to shift accordingly, thereby enhancing the user's interaction experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If objects in virtual space rotate with the device orientation changes, then the virtual space presentation adapts to device orientation, but the user experience deteriorates because objects do not appear anchored to the real world
Solution Approach 1:
Instead of rotating objects with device orientation changes, the patent inverts the approach by keeping objects fixed in the virtual space while rotating the field of view. This inversion resolves the contradiction by maintaining object stability (improving reliability) while still adapting the view to device orientation (maintaining adaptability).
Solution Approach 2:
The patent introduces a new dimension of rotation by rotating the field of view around the vertical axis (Y-axis) rather than rotating objects in the traditional X-Z plane. This dimensional change allows the virtual space to adapt to device orientation while keeping objects anchored, resolving the contradiction between adaptability and reliability.
2Reliability
If the field of view rotates in virtual space to simulate real-world rotation, then user immersion improves, but system complexity increases
Solution Approach 1:
The patent extracts the rotation operation from objects and applies it only to the field of view. By separating the rotation function from object transformation and applying it only to the viewing perspective, the system achieves immersion without the complexity of rotating and repositioning multiple virtual objects.
Solution Approach 2:
The field of view rotation mechanism serves multiple functions: it simulates real-world rotation, maintains object anchoring, and adapts to device orientation. This multi-functionality achieves high immersion quality without requiring separate complex mechanisms for each function, thereby limiting the increase in system complexity.

AI summary
An enhanced system and method presents a view of a virtual space on a display based on a position of the display in one or more degrees of freedom. For such a position of the display, a corresponding field of view in the virtual space may be determined. In some examples, as the display rotates about an axis that runs perpendicular to the display through a centroid of the display, the view of the virtual space may shift such that the field of view varies dynamically with the rotational position of the display and the objects in the field of view are maintained fixed in the virtual space. In some implementations, an object of the virtual space may be controlled by the position change of the display in the degrees of freedom such that the objects may be steered according to the display's position in the degrees of freedom.
