Solution Overview
Problem
Existing display control technologies require cumbersome operations to indicate and interact with objects in a three-dimensional space, involving substantial motion and additional steps to control line segments or touch panels.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple indicator bodies are used to indicate optional points in three-dimensional space, then the ability to operate on multiple points is improved, but the complexity of the operation process increases
Solution Approach 1:
The patent combines multiple indicator bodies (fingers) into a single operational unit by recognizing the intersection point of operating lines from multiple fingers as a unified control point. This allows multiple fingers to work together to indicate a single optional point, improving versatility while maintaining operational simplicity through the unified intersection point recognition mechanism.
Solution Approach 2:
The patent introduces operating lines as intermediary elements that extend from indicator bodies to the object. These operating lines serve as mediators that translate the position and orientation of multiple indicator bodies into a recognized operating position through their intersection, simplifying the operation process by providing a clear geometric relationship between the user's input and the system's interpretation.
2Measurement precision
If the endpoint of a line segment is placed to an optional point by moving the indicator body, then the indication accuracy is improved, but the motion required increases
Solution Approach 1:
The patent transitions from moving the indicator body endpoint directly to the target point to using the intersection point of operating lines as the indication target. This dimensional shift allows the system to recognize the operating position based on the geometric intersection of lines extending from multiple indicator bodies, improving indication accuracy while reducing the motion required since the intersection point is automatically calculated rather than physically moved.
3Measurement precision
If additional operations are performed to control line segment length, then the precision of point indication is improved, but the number of operations increases
Solution Approach 1:
The patent implements a self-service mechanism where the operating lines automatically extend from the indicator bodies to intersect at the target point. The system self-determines the operating position through the intersection of these lines without requiring additional user operations to control line segment length or adjust precision parameters, thereby maintaining point indication precision while reducing the total number of operations required.
4Adaptability or versatility
If multiple operations such as touching and moving on a touch panel are performed, then the flexibility of indication is improved, but the operational complexity increases
Solution Approach 1:
The patent inverts the conventional touch panel approach by not requiring users to touch and move the panel surface to indicate points. Instead, the system recognizes operating positions based on the spatial relationship and intersection of operating lines extending from indicator bodies in three-dimensional space. This inversion maintains indication flexibility by allowing indication from various spatial positions while reducing operational complexity by eliminating the need for touch panel interaction.
