Graph Color Density Differentiation for Selection Clarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices, such as scientific calculators, lack an efficient method to visually distinguish between multiple graphs displayed on a screen, making it difficult for users to select the intended graph.
Innovation Solution
The electronic device includes a display and at least one processor that shows a selection screen to set a selected graph and unselected graphs, with the selected graph displayed in full color density and unselected graphs displayed with a lower color density, allowing users to easily recognize the selected graph.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple graphs are displayed on the screen without differentiation, then the display shows all graphs with equal visibility, but users cannot easily distinguish which graph is selected and which is not
Solution Approach 1:
The patent applies color density differentiation to visually distinguish between selected and unselected graphs. The selected graph is displayed with higher color density (full color) while unselected graphs are displayed with lower color density (dimmed or grayscale), enabling users to easily identify the selected graph without additional labels or markers.
Solution Approach 2:
The patent applies different display qualities to different graphs based on their selection status. Instead of uniform display treatment, the system applies full color density to the selected graph and reduced color density to unselected graphs, creating local differentiation that conveys selection information effectively.
2Difficulty of detecting and measuring
If all graphs are displayed with the same color density, then the display is simple and uniform, but users experience difficulty in identifying the selected graph among multiple graphs
Solution Approach 1:
The system implements visual differentiation through color density modulation rather than complex graphical overlays or annotations. By adjusting the color density parameter of each graph based on its selection status, the system achieves clear identification of the selected graph with minimal additional processing complexity.
Solution Approach 2:
The patent changes the display parameter of color density to convey selection information. This parameter-based differentiation allows the system to maintain simple display logic while achieving effective graph identification, as the change in color density is perceptually significant but computationally straightforward.
3Ease of operation
If the selected graph is highlighted with high color density, then the selected graph becomes visually distinct and easy to identify, but the overall display complexity increases due to differentiation requirements
Solution Approach 1:
The system uses color density modulation as a simple yet effective differentiation mechanism. The selected graph is rendered with full color density while unselected graphs use reduced color density, creating clear visual distinction without requiring complex highlighting effects, borders, or annotations that would increase processing complexity.
Solution Approach 2:
The patent segments the graph display into two distinct visual categories: selected graphs with high color density and unselected graphs with low color density. This segmentation approach allows the system to treat different graphs differently based on selection status while maintaining simple processing logic through straightforward conditional rendering.

AI summary
Provided is an electronic device including a display and at least one processor. The at least one processor: shows on the display a selection screen for accepting a first selection operation to set, as a selected graph, a graph predetermined first information of which is to be shown among a plurality of graphs shown on the display with coordinate axes, and to set, as an unselected graph, one or more remaining graphs the first information of which is not to be shown; shows on the display a first information display screen on which the first information relating to the selected graph is shown with the coordinate axes and the plurality of graphs when the selected graph is confirmed on the selection screen; and displays the unselected graph among the plurality of graphs with a lower color density than a color density of the selected graph on the selection screen.
