Dynamic Menu Balloon Indicator for Touch Display Ambiguity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display systems often fail to accurately indicate the clicked icon when a pop-up menu is displayed, especially when the clicked position is near the edge of the screen, leading to ambiguity about which icon triggered the menu, particularly in touch panel interfaces where no pointer is visible.
Innovation Solution
A display apparatus that includes a detection unit to identify the operation position and a controller to dynamically position the menu and a balloon indicator at the operation position, ensuring the entire menu is visible by adjusting its placement based on available screen space, such as displaying it above, to the left, right, or below the click point, and aligning it centrally if necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the menu is displayed at a fixed predetermined position, then the menu display position is determined, but the menu may not be fully visible when clicked near screen edges and it becomes unclear which icon was clicked
Solution Approach 1:
The menu display position is changed from fixed to dynamic, automatically adjusting its position based on the clicked location. The controller calculates the optimal menu position to ensure full visibility while maintaining association with the clicked icon, resolving the contradiction between fixed positioning and adaptive visibility.
Solution Approach 2:
A balloon indicator is introduced as an intermediary element to clearly mark the clicked position. The balloon serves as a visual mediator between the menu and the clicked icon, ensuring users can identify which icon triggered the menu even when the menu is repositioned for optimal visibility.
2Ease of operation
If the menu is repositioned to ensure full visibility, then menu visibility improves, but the association between the menu and clicked icon may become unclear
Solution Approach 1:
The balloon indicator acts as an intermediary that preserves click position information while the menu is repositioned. The balloon remains anchored to or near the clicked icon, providing continuous visual reference that maintains the association between the menu and its trigger, even when the menu moves to an optimal display position.
Solution Approach 2:
The visual indication system is enhanced by replacing reliance on spatial proximity alone with an explicit graphical indicator (balloon). This substitution ensures that the association between menu and clicked icon is maintained through a dedicated visual marker rather than solely through positional relationship.
3Device complexity
If no indicator is displayed, then the interface remains simple, but it is difficult to know which icon is clicked to display the menu
Solution Approach 1:
The balloon indicator is introduced as a minimal intermediary element that provides precise click identification without significantly increasing interface complexity. The balloon serves as a simple visual marker that clearly indicates which icon was clicked, maintaining interface simplicity while resolving the identification ambiguity.

AI summary
A display apparatus includes a display, a detection unit that detects an operation position of a user on the display, and a controller that displays an entire menu corresponding to the detected operation position at a position corresponding to the operation position, and displays a balloon indicating the operation position.
