3D User Interface Polyhedron Manipulation on Mobile Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminals lack convenient methods for manipulating and changing the display state of 3D user interfaces, specifically in terms of enlargement, reduction, and rotation, which limits user interaction with 3D objects in virtual spaces.
Innovation Solution
A mobile terminal equipped with a user input unit, display unit, and controller that allows users to select and change the display state of 3D objects by receiving inputs for enlargement, reduction, rotation, and scrolling of polyhedrons within a virtual stereoscopic space, enabling intuitive manipulation of 3D user interfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional 2D display interfaces are used for 3D objects, then device complexity is reduced, but ease of operation deteriorates due to limited manipulation capabilities
Solution Approach 1:
The patent transitions from conventional 2D display interfaces to a 3D stereoscopic display interface, adding a new dimension to the user interface. This allows users to manipulate 3D objects with natural gestures (enlargement, reduction, rotation, scrolling) in a virtual 3D space, significantly improving ease of operation for 3D content while managing the complexity through software-based rendering
2Adaptability or versatility
If basic display functions are provided, then device complexity is minimized, but adaptability deteriorates due to inability to perform enlargement, reduction, and rotation operations
Solution Approach 1:
The patent implements a universal 3D user interface system that can perform multiple operations (enlargement, reduction, rotation, scrolling) on various types of 3D objects (polyhedrons, spheres, cylinders, cones) within a single integrated framework. The controller is designed to handle diverse manipulation requests through a unified set of commands, achieving high adaptability without proportionally increasing device complexity
3Ease of operation
If detailed control of 3D object display states is enabled, then ease of operation improves, but loss of information increases due to complexity of control parameters
Solution Approach 1:
The patent creates a virtual copy of the physical 3D space on the display unit, where users can manipulate objects through intuitive gestures that mirror real-world interactions. The controller translates simple user gestures (touch, drag, pinch) into complex 3D transformations, maintaining ease of operation while preserving complete control information through the virtual environment mapping

AI summary
A mobile terminal and controlling method thereof are disclosed. The present invention includes displaying a 3D user interface including at least one 3D object on a display unit, selecting at least one stereoscopic region from the 3D user interface by a first input via a user input unit, displaying at least one polyhedron corresponding to each of the selected at least one region on the display unit, and changing a display state of each of the at least one polyhedron to correspond to a second input via the user input unit, wherein the step of changing the display state is performed to enlarge, reduce, rotate or scroll the at least one polyhedron according to the second input. Accordingly, the present invention provides a 3D user interface using a 3D object arranged in a virtual 3D space, thereby facilitating a user to manipulate a mobile terminal with a new visual effect.
