Graph Display Control Device with Color-Matched Parameter Sliders
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In graph function electronic calculators, it is difficult to discriminate which graph image corresponds to a parameter being changed when displaying multiple graph images based on different function formulas, making it hard to analyze the changes effectively.
Innovation Solution
A graph display control device and method that uses parameter sliders with colors matching the corresponding function formulas, allowing users to easily identify and change parameter values, with the sliders' colors aligning with the graph images, facilitating discrimination and analysis.

If multiple graph images are displayed based on different function formulas, then the ability to analyze multiple functions simultaneously is improved, but the ability to discriminate which graph image corresponds to a changed parameter deteriorates
Solution Approach 1:
The patent applies color coding to parameter sliders, where each slider is displayed in a color that matches its corresponding function formula and graph image. This visual differentiation allows users to easily identify which graph image will change when a specific parameter is modified, resolving the discrimination difficulty while maintaining multi-function analysis capability
Solution Approach 2:
The parameter slider acts as an intermediary element between the function formulas and graph images. By displaying the slider in a color that matches both the function formula and its corresponding graph image, it serves as a visual mediator that connects and identifies the relationship between parameters, formulas, and their graphical representations
