Pressure-Sensitive Touch Panel Display Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch panel operations require multiple touches and long finger movements, making them difficult to understand and tiring, especially when switching to list displays, as they are not easily accessible with simple operations.
Innovation Solution
An electronic device with a touch panel and pressure detection unit that allows users to switch to list display with a small number of intuitive touch operations by varying touch pressure and movement, enabling easy selection of items from multiple images or web pages through scrolling and resizing images based on touch inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a user performs multiple touches to complete an operation on the touch panel, then the operation can be completed, but the operation becomes difficult to understand and the user feels weary
Solution Approach 1:
The patent applies parameter changes by utilizing pressure as an additional control dimension. When pressure exceeding a threshold is detected during a touch operation, the system transitions from single-image display to multi-reproduction display mode. This allows the operation to be completed in one intuitive gesture rather than requiring multiple separate touches, thereby improving ease of operation while maintaining reasonable operation time
Solution Approach 2:
The patent introduces pressure as an additional dimension for touch panel control. By detecting pressure in addition to touch position, the system can distinguish between different types of operations (single display vs. multi-reproduction display) without requiring multiple sequential touches. This dimensional addition enables more complex operations to be performed more efficiently
2Adaptability or versatility
If the procedure of the operation becomes long, then more operations can be performed, but the distance at which the user moves the finger on the touch panel becomes long and the user feels weary
Solution Approach 1:
The patent uses pressure parameter changes to enable versatile operations within a compact interaction space. By detecting pressure thresholds, the system provides access to different display modes (single vs. multiple images) without requiring the user to navigate through multiple screens or perform long finger movements, thus maintaining ease of operation while enhancing adaptability
Solution Approach 2:
The system prepares multiple display modes in advance, with the multi-reproduction display pre-configured to show multiple images simultaneously. When pressure is detected, the transition to this pre-prepared mode occurs instantly, eliminating the need for users to perform sequential operations to access different display configurations
3Adaptability or versatility
If existing touch panel operations are used to switch to list display, then list display can be accessed, but it requires multiple touches and is not easily accessible with simple operations
Solution Approach 1:
The patent simplifies display mode switching by using pressure parameter changes. When pressure exceeding a threshold is detected during a touch operation, the system directly switches to multi-reproduction display mode, which functions as a list display showing multiple images simultaneously. This eliminates the need for multiple touches or complex navigation sequences, reducing operation complexity while maintaining versatile display mode switching capability

AI summary
In a case where a pressing force exceeding a first pressure on a display unit is detected in displaying detailed information about a particular item as a detailed information display screen on the display unit, the display of the display unit is switched to a list screen for displaying a plurality of items, and thereafter, in a case where an operation of moving a touch position is performed with a touch performed before the switching not being released, scrolling display switching at least some of the plurality of items displayed on the list screen is performed.
