Touch-Driven Screen Layout Switching in Image Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display devices require complex operations and user burden to switch between single-screen and multiple-screen displays or change layouts, often leading to operating errors due to non-intuitive interface requirements.
Innovation Solution
An image display device with a touch detection system that detects touch operations to generate touch information, allowing users to switch between single-screen and multiple-split screen displays and change layouts by interpreting touch gestures, such as taps, flicks, and swipes, to execute predefined screen switching processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch panel is used to enable direct screen interaction, then ease of operation is improved, but device complexity increases due to the need for touch detection sections and complex operation judgment logic
Solution Approach 1:
The touch panel serves as an intermediary between the user and the display system, translating physical touch gestures into digital commands. The touch detection section and operation judgment section act as mediators that convert user intentions (touch gestures) into system actions (screen switching, layout changes), simplifying the user interface while managing the complexity internally through dedicated processing components.
2Adaptability or versatility
If multiple different operations are required for different display functions, then adaptability is improved, but ease of operation deteriorates due to the need for users to memorize multiple operation patterns
Solution Approach 1:
Instead of requiring users to learn multiple different operations for different functions, the system inverts the approach by making each screen or display region respond to a standard tap gesture in its own way. Each screen position contains embedded information about its function and current state, so that a universal tap operation adapts to the specific context, reducing memorization burden while maintaining versatility.
Solution Approach 2:
The system changes parameters such as the number of screens, their positions, and their functions dynamically based on touch operations. By allowing the display configuration itself to encode operational information (e.g., which screen should be expanded, which layout to switch to), the system adapts its behavior to the current state rather than requiring fixed operation patterns for each function.
3Reliability
If complicated remote control or key operations are required for screen switching, then reliability of precise control is improved, but productivity deteriorates due to the time and steps required for operations
Solution Approach 1:
The system performs preliminary actions by pre-configuring the display screens with embedded operational information and pre-establishing the relationship between touch positions and display regions. When a user taps a screen, the system has already prepared the necessary data and logic to execute the appropriate action immediately, eliminating the need for multiple confirmation steps or menu navigations required by traditional remote control systems.

AI summary
An image display device includes a video signal input section that receives a plurality of video signals, a display section that displays, on one or more display screens, an image(s) corresponding to a predetermined video signal(s), a touch detection section that detects a start position and touch release position of a user's touch operation and generates touch information composed of the touch start position and the touch release position, a storage section storing display screen information, a touched position acquisition section that acquires input detection information with reference to the touch information, an input operation judgment section that judges the user's touch operation with reference to the display screen information and the input detection information and determines a screen switching process associated in advance with the touch operation, and a display screen switching section that executes the screen switching process.
