Mobile Display Scaling for Hyperlink Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile terminal devices, the small display area makes it difficult to select and operate buttons, icons, and hyperlinks, especially when viewing web pages designed for PCs, leading to complicated operations and reduced user convenience due to the need for successive specification of display scaling factors for selection and viewing.
Innovation Solution
A terminal apparatus with a display control unit that detects first and second selection operations to change the display mode, allowing for temporary scaling adjustments for easier selection and reverting to the original mode for viewing, using a touch panel to perform double tap operations for scaling changes and single tap operations for hyperlink selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display scaling factor is increased to make buttons and icons larger for easier selection, then the ease of operation is improved, but the display area for viewing content is reduced
Solution Approach 1:
The display scaling factor is made dynamically adjustable based on user interaction. When a user performs a first selection operation (e.g., double-tap) in a given area, the scaling factor is temporarily increased for that area to facilitate selection. After the selection is made, the scaling factor automatically returns to the original value, allowing the full display area to be utilized for viewing content.
Solution Approach 2:
The display scaling is applied locally to the specific area where the user performs the selection operation, rather than globally to the entire screen. This allows other areas of the display to maintain their original scaling and full visibility, thus preserving the overall display area while improving ease of operation in the targeted local region.
2Ease of operation
If the display scaling factor is successively changed for selection operation, then the ease of operation is improved, but the device complexity increases due to multiple scaling states
Solution Approach 1:
The display scaling factor is made dynamically adjustable based on user interaction. When a user performs a first selection operation (e.g., double-tap) in a given area, the scaling factor is temporarily increased for that area to facilitate selection. After the selection is made, the scaling factor automatically returns to the original value, allowing the full display area to be utilized for viewing content.
Solution Approach 2:
The modified display scaling state is temporary and automatically discarded after the selection operation is completed. The system recovers the original display scaling factor, ensuring that only one scaling state needs to be managed at any time. This approach avoids the complexity of managing multiple persistent scaling states while still providing the benefit of temporary scaling enhancement for selection operations.
3Area of stationary object
If the screen is displayed at full size to maximize display area, then the display area is improved, but the ease of operation deteriorates due to smaller button and icon sizes
Solution Approach 1:
The display scaling factor is made dynamically adjustable based on user interaction. When a user performs a first selection operation (e.g., double-tap) in a given area, the scaling factor is temporarily increased for that area to facilitate selection. After the selection is made, the scaling factor automatically returns to the original value, allowing the full display area to be utilized for viewing content.
Solution Approach 2:
The display scaling is applied locally to the specific area where the user performs the selection operation, rather than globally to the entire screen. This allows other areas of the display to maintain their original scaling and full visibility, thus preserving the overall display area while improving ease of operation in the targeted local region.
4Adaptability or versatility
If web pages designed for PC are displayed on mobile phone, then the adaptability is improved, but the ease of operation worsens due to inappropriate hyperlink positioning and size
Solution Approach 1:
The display scaling factor is made dynamically adjustable based on user interaction. When a user performs a first selection operation (e.g., double-tap) in a given area, the scaling factor is temporarily increased for that area to facilitate selection. After the selection is made, the scaling factor automatically returns to the original value, allowing the full display area to be utilized for viewing content.
Solution Approach 2:
The display scaling is applied locally to the specific area where the user performs the selection operation, rather than globally to the entire screen. This allows other areas of the display to maintain their original scaling and full visibility, thus preserving the overall display area while improving ease of operation in the targeted local region.

AI summary
A terminal apparatus includes a display, a display control unit configured to display a screen on the display in a given display mode, a first selection operation detection unit configured to detect that a first selection operation concerning the given display mode has been performed in a given area of the screen, and a second selection operation detection unit configured to detect that a second selection operation concerning given processing has been performed in the given area of the screen. The display control unit displays a screen by changing to a second display mode based on detection of the first selection operation in the screen displayed in a first display mode, performs the given processing based on detection of the second selection operation, and performs display control processing for displaying a screen in the first display mode after the given processing.
