Information Display Terminal Z-Axis Object Scrolling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing graphical user interface (GUI) systems in three-dimensional virtual spaces face challenges in maintaining visibility and operability due to overlapping objects, which hinder intuitive interaction and navigation.
Innovation Solution
The information display terminal employs a touch panel and touch pad with contact sensors to detect location and scroll information, allowing users to scroll and move objects along the z-axis and x-y plane, and adjust the viewpoint, thereby improving visibility and operability by controlling the display of objects based on detected input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple objects are displayed in a three-dimensional virtual space, then the visibility and operability are improved, but objects overlap and hinder intuitive interaction
Solution Approach 1:
The patent introduces a third dimension (depth/z-axis) to the traditional two-dimensional display space. Objects can be positioned at different depths along the z-axis, allowing multiple objects to coexist without overlapping in the same visual plane. This dimensional expansion resolves the contradiction by enabling both multiple objects to be displayed and maintained visibility through depth-based layering.
Solution Approach 2:
The patent implements dynamic viewpoint control where the projection plane and object positions can be adjusted in real-time based on user interaction. The system dynamically changes the projection angle and depth positioning to optimize object visibility and reduce overlap, transforming a static display into a dynamic spatial arrangement that adapts to interaction needs.
2Ease of operation
If objects are arranged in three-dimensional space, then operability is improved, but navigation and control become more complex
Solution Approach 1:
The patent employs a projection plane that serves multiple functions simultaneously: it acts as the display surface, the interaction plane, and the reference frame for depth positioning. This multi-functional design simplifies navigation control by providing a universal interface that handles both 2D plane operations and 3D depth management, reducing the complexity of controlling three-dimensional arrangements.
3Loss of information
If the viewpoint is fixed, then the display is stable, but visibility of multiple objects is reduced
Solution Approach 1:
The patent transforms the fixed viewpoint into a dynamic adjustable viewpoint. The projection plane can be rotated and repositioned along the z-axis based on user input, allowing the system to adapt the viewing angle to optimize visibility of different objects. This dynamic adjustment resolves the contradiction by enabling both improved visibility through viewpoint changes and maintained stability through controlled, user-directed transformations.
