3D Interface Object Rotation Radius Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional interfaces are inadequate for managing and interacting with objects in a three-dimensional space, as they primarily operate in two-dimensional spaces and lack the necessary functionality for rotation and spatial manipulation.
Innovation Solution
A method and apparatus that allow objects to be rotated in a three-dimensional space by determining the radius of rotation based on their distance from a rotation axis and controlling their movement in response to user inputs, such as dragging or touch commands, while also adjusting the disposition of subordinate objects on a screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional two-dimensional interface methods are used, then the interface is simple to implement, but it cannot support rotation and spatial manipulation of objects in three-dimensional space
Solution Approach 1:
The patent extends the conventional two-dimensional interface to three-dimensional space by introducing depth as an additional dimension. Objects are positioned and manipulated in 3D space with coordinates (x, y, z), enabling rotation and spatial manipulation that were impossible in 2D. The interface maintains compatibility with traditional 2D displays while adding 3D interaction capabilities through virtual depth representation.
2Ease of operation
If objects are allowed to rotate in three-dimensional space, then spatial manipulation is enhanced, but the complexity of determining rotation parameters increases
Solution Approach 1:
The patent determines rotation parameters dynamically based on the object's position in 3D space. The radius of rotation is calculated from the distance between the object and the rotation axis, creating a direct relationship between position and rotation behavior. This parameter-based approach simplifies control by automatically adjusting rotation characteristics according to spatial context rather than requiring separate control mechanisms.
Solution Approach 2:
The system automatically determines rotation parameters based on the object's own position and the rotation axis location. The radius of rotation is self-calculated from the geometric relationship between the object and axis, eliminating the need for manual parameter specification. The interface self-adjusts to provide intuitive rotation control without increasing operational complexity.
3Loss of information
If subordinate objects are displayed when dragging a superordinate object, then object relationships are clarified, but the screen space requirement increases
Solution Approach 1:
The patent resolves the screen space conflict by displaying subordinate objects in a virtual three-dimensional space rather than occupying additional two-dimensional screen area. Multiple objects can be positioned at different depth levels, allowing relationship visualization without proportional increases in screen real estate. The 3D spatial arrangement enables information density to be maintained while improving relationship clarity.

AI summary
A method and apparatus for interfacing includes outputting at least one object to a display embodying a three-dimensional space and determining a radius of rotation of the at least one object, based on a distance between the at least one object and a rotation axis in the three-dimensional space. The method and apparatus further include controlling the at least one object to rotate around the rotation axis based on the radius of rotation when a rotation command for the at least one object is received.
