Touch Panel Display Device with Image-Specific Scroll Direction Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices that simultaneously display information from multiple sensors on a split screen often confuse users due to a lack of unified operation feel, especially when using touch panels, as intuitive operations are not consistent across images.
Innovation Solution
A display device configuration that includes a detector, image acquirer, display unit, gesture detector, operated location detector, divided area identifier, and image processor, which detects touch operations and adjusts scrolling and zooming based on the characteristics of each image displayed in separate areas, ensuring operations align with the image being interacted with.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display screen is divided to simultaneously display multiple sensor images, then information display capability is improved, but operation consistency deteriorates
Solution Approach 1:
The patent applies local quality by assigning different operation characteristics to different divided areas of the display screen. Each sensor image area has its own scroll direction settings - for example, the radar image area allows scrolling in all directions while the sonar image area restricts scrolling to specific directions. This enables each local area to have operation properties optimized for its specific image type, resolving the contradiction between displaying multiple images and maintaining operation consistency.
2Adaptability or versatility
If different operation methods are used for each image, then image-specific characteristics are improved, but user confusion increases
Solution Approach 1:
The patent implements universality through a unified touch panel interface that handles multiple sensor image types (radar, sonar, GPS navigation). The same touch input mechanisms work across all image types, but the system universally applies image-appropriate scroll direction constraints. This allows the interface to be versatile enough to handle different image characteristics while maintaining consistent interaction methods, reducing user confusion.
Solution Approach 2:
Different scroll direction constraints are applied to different image areas based on their characteristics. For instance, radar images may allow 360-degree scrolling while sonar images restrict scrolling to forward-looking directions. This local differentiation enables each image type to display its specific characteristics appropriately while the overall system remains unified.
3Measurement precision
If scroll direction is restricted for certain images, then image interpretation accuracy is improved, but operational flexibility deteriorates
Solution Approach 1:
The patent applies local quality by implementing image-specific scroll direction constraints in different divided areas of the display. For example, sonar images may restrict scrolling to forward directions only to improve interpretation accuracy, while radar images allow full 360-degree scrolling for maximum operational flexibility. Each area's scroll behavior is optimized for its specific image type.
Solution Approach 2:
The system dynamically adjusts scroll behavior based on the type of image being displayed and the direction of user input. The scroll direction constraints are not fixed but adapt to the specific image context, allowing the system to maintain both accuracy and flexibility as needed for different sensor data visualizations.

AI summary
A touch panel device (display device) acquires a first sensor image (31), a second sensor image (32), and a third sensor image (33). The touch panel device displays acquired images in respective divided areas of a display screen. The touch panel device detects a predetermined touch gesture and detects an operated location of the touch gesture. The touch panel device identifies which image the operated location indicates. The touch panel device performing processing corresponding to the identified touch gesture (scrolling or zooming of a display image), and changes a direction or a motion range of the processing according to the identified sensor image.
