User Interface Shape Interaction Control via Radius Modification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques for user interaction with shapes in a user interface lack intuitiveness and are difficult for casual users to learn, leading to a frustrating and inefficient trial-and-error process.
Innovation Solution
A method where a shape is displayed using a plurality of points with associated radii, allowing users to modify these radii directly, with the system determining and adjusting neighboring points to prevent intersections, enabling intuitive and natural control of shape manipulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional vector points and handles are used for shape manipulation, then shape editing capability is provided, but user intuitiveness and ease of operation deteriorate
Solution Approach 1:
The patent introduces radius values as intermediary parameters that mediate between user input and shape manipulation. Instead of directly manipulating complex vector handles, users interact with simplified radius values that automatically translate into appropriate shape modifications, making the interface more intuitive while maintaining editing capability
Solution Approach 2:
The system automatically adjusts neighboring points and handles based on the modified radius values without requiring manual intervention. The shape manipulation system self-regulates by determining appropriate adjustments to maintain geometric integrity, reducing the burden on users to understand complex vector relationships
2Productivity
If users manually adjust vector points and handles, then shape modification is achieved, but time consumption and productivity deteriorate
Solution Approach 1:
The system pre-calculates and automatically applies adjustments to neighboring points and handles based on the modified radius. This preliminary action eliminates the need for users to manually adjust multiple vector parameters, significantly reducing trial-and-error time and improving editing efficiency
Solution Approach 2:
The patent implements automatic feedback mechanisms where the system continuously monitors and adjusts shape parameters based on radius modifications. This feedback loop ensures that shape changes are applied correctly without requiring user verification, speeding up the editing process
3Ease of operation
If radius modification causes point intersection, then direct control is achieved, but geometric validity deteriorates
Solution Approach 1:
The system applies preliminary anti-action by automatically adjusting neighboring points and handles before finalizing the shape modification. This preventive measure counteracts potential intersections caused by radius changes, maintaining geometric validity while preserving direct user control
Solution Approach 2:
The patent dynamically changes parameters of neighboring points (such as their positions or handle values) in response to radius modifications. This parameter adjustment ensures that geometric constraints are maintained even when users directly control radius values, preventing invalid geometries

AI summary
Techniques to control shape interaction in a user interface are described. In one or more implementations, a method is described of controlling user interface shape interaction by a computing device. A shape is displayed in a user interface by the computing device, the shape described using a plurality of points, each of the points having an associated radius. An input is detected, by the computing device, involving modification of the associated radius of least one of the plurality of points. A determination is made, by the computing device, whether modification of the associated radius of the at least one point causes an intersection of the associated radius of one or more of the plurality of points neighboring the at least one point. Responsive to the determination that the modification causes the intersection, the associated radius of the one or more points are modified such that the intersection does not occur. The shape is displayed by the computing device as having the modified associated radius of the at least one point.
