Dynamic Soft Key Repositioning for Large Vehicle Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large vehicle displays struggle to maintain operability and visibility of soft keys, as they are often not displayed in easily accessible positions, leading to confusion and decreased usability, especially when multiple contents are displayed simultaneously.
Innovation Solution
A display device with integrated touch panel that includes position detection and content layout determination means, allowing for dynamic repositioning of contents based on priority and user intent, ensuring soft keys are displayed in high visibility positions with minimal line of sight movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a large display is used to show multiple contents, then the information display capability is improved, but the soft key operability deteriorates because it cannot be displayed in an easy-to-view position
Solution Approach 1:
The patent implements dynamic layout adjustment where the display controller automatically repositions soft keys based on detected hand positions. The system transitions from static content arrangement to dynamic repositioning, allowing soft keys to move between different display regions (first region for viewing, second region for operation) based on real-time user interaction detection.
Solution Approach 2:
The patent introduces hand detection technology as an intermediary between the user and the display system. The detection unit senses hand position and proximity, serving as a mediator that triggers automatic soft key repositioning. This intermediary enables the system to adapt layout without requiring explicit user commands or physical adjustment of display components.
2Area of stationary object
If the display size is increased, then the content display capacity is improved, but the distance to soft keys increases making them harder to operate
Solution Approach 1:
The system dynamically adjusts soft key positions based on hand detection data. When a hand approaches, the soft key moves from a distant first region to a nearer second region, maintaining accessibility despite the large overall display size. This dynamic repositioning compensates for the increased distance inherent in larger displays.
Solution Approach 2:
The patent creates different display regions with different functional qualities: a first region optimized for content viewing and a second region optimized for operation. The soft key can be displayed in either region depending on the operational context, allowing each region to serve its specific purpose while maintaining overall system effectiveness.
3Adaptability or versatility
If multiple soft keys are displayed simultaneously, then the functionality is improved, but the user becomes confused about which key to press
Solution Approach 1:
The patent assigns different spatial qualities to different soft keys by positioning them in distinct display regions. The active soft key that requires user input is positioned in the second region (easier to access), while other soft keys remain in the first region. This spatial differentiation helps users identify which key to press among multiple available options.
Solution Approach 2:
The system dynamically repositions soft keys based on operational state. When a specific soft key becomes active or requires input, it moves to the second region for emphasis and easier access. This dynamic highlighting through positional change guides user attention and reduces confusion about which key to operate.
4Ease of operation
If the position of armrest switch is adjusted, then soft key visibility is improved, but operability may decrease for some drivers
Solution Approach 1:
The patent replaces fixed physical switch positioning with hand detection technology as an intermediary. The system detects hand position and proximity automatically, eliminating the need for drivers to adjust physical switch positions. This adaptive detection mechanism accommodates different driver body types and positions without requiring manual configuration.
Solution Approach 2:
The system performs automatic soft key repositioning based on hand detection without requiring driver intervention. The display controller autonomously adjusts soft key positions based on detected hand coordinates, eliminating the need for drivers to manually adjust switch positions or configure display settings, thus serving different drivers adaptively.

AI summary
A display device 100 for displaying content on a display 12, integrated with a touch panel 23, includes position detection means 32 for detecting a position indicated on the display; and content layout determination means 33 for determining a layout of a plurality of contents displayed on the display wherein, when the position detection means detects that a predetermined position on the display is indicated or a display position of a predetermined content is indicated, the content layout determination means moves at least one of displayed contents, based on a priority of displayed contents predetermined according to the display contents displayed on the display, and displays a soft key at a position where a line of sight movement amount is smaller than a line of sight movement amount of the content.
