Guide-Object UI for Precise Wide-Range Parameter Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user interfaces for setting values, such as sliders, require precise and small operations due to large adjustable ranges, often leading to difficulties in intuitively changing values beyond the display resolution, especially when upper and lower limits are not defined.
Innovation Solution
A user interface that utilizes a guide object with two ends to calculate a movement amount based on user operations, allowing for intuitive value setting without relying on absolute limits, by displaying an operation-target object and updating a subject parameter with a change amount corresponding to the movement amount.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a slider is used to control a parameter with a large adjustable range (e.g., 0 to 65535), then the parameter can be controlled, but the operation required becomes very small and imprecise due to display resolution limitations
Solution Approach 1:
The patent changes the parameter mapping from absolute position-based control to movement量-based control. Instead of mapping the slider position directly to the parameter value (which causes precision loss over large ranges), the system calculates the change amount based on the movement distance and applies it to the current value. This allows the same slider operation to produce consistent, precise changes regardless of the current parameter value or display resolution.
2Adaptability or versatility
If the slider range is made large to accommodate wide adjustable ranges, then more values can be controlled, but the minimum operation amount becomes too small to reliably achieve desired changes
Solution Approach 1:
The patent introduces an intermediary calculation layer between the slider operation and the parameter change. The movement amount (calculated from slider position change) serves as an intermediary that translates user input into a standardized change amount. This intermediary layer decouples the slider's visual range from the actual parameter adjustment, allowing the slider to span a wide range while maintaining consistent, easily controllable operation steps.
3Productivity
If the focus height value is increased by a large amount (e.g., 100) due to display resolution limitations, then the parameter changes, but the control becomes less precise and intuitive
Solution Approach 1:
The patent implements feedback by continuously calculating the movement amount based on the current slider position and the previous position, then applying this calculated change amount to update the parameter. This feedback loop ensures that each operation produces the intended precise change, regardless of display resolution or current parameter value. The system monitors and adjusts based on actual movement to maintain both speed and precision.

AI summary
An information processing device includes: an input unit that receives a user operation; an output unit that causes an image to be displayed on a display; and a processing unit. The processing unit calculates a first movement amount in accordance with a first user operation associated with a guide object having two ends, and updates a subject parameter with a first change amount corresponding to the first movement amount.
