Vehicle Touch Slider Enlargement for Unobstructed Setting Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems face issues with visibility and operability when using sliders and thumbs for setting operations, as they are often obscured by a user's hand or finger, impairing the ability to confirm setting details.
Innovation Solution
A vehicle display apparatus with a display processor that enlarges the display of sliders and thumbs upon continuous touch for a predetermined time and reverts to normal size after a second predetermined time, enhancing visibility and operability by ensuring the user can confirm settings without obstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display shows slider and thumb with normal size, then the display can show more information, but the user cannot confirm setting details due to obstruction by hand or finger
Solution Approach 1:
The display dynamically changes the size of the slider and thumb based on touch detection. When the operation detector detects finger touch on the display region, the display processor enlarges the slider and thumb to improve visibility. When no touch is detected, the display returns to normal size to maintain information density. This dynamic adaptation resolves the contradiction between visibility and information display capacity.
Solution Approach 2:
The display processor changes the display parameter (size) of the slider and thumb based on touch detection state. The system transitions between two size states: normal size for general operation and enlarged size for confirmation phase. This parameter change allows the same display element to serve different functional requirements at different times.
2Loss of information
If the display enlarges slider and thumb continuously, then visibility is improved, but the display cannot return to normal size to show other information
Solution Approach 1:
The display alternates between normal size and enlarged size based on periodic touch detection. The operation detector continuously monitors touch state, and the display processor switches between size states accordingly. This periodic action ensures the display provides enlarged view only when needed for confirmation, while maintaining normal information density at other times.
Solution Approach 2:
The display size is not fixed but dynamically adjusted based on user interaction state. The system transitions from static normal size to dynamic size adaptation, enlarging only when touch is detected and returning to normal size when touch is released. This dynamic behavior resolves the contradiction by making the display area flexible rather than permanently occupied by enlarged elements.
3Area of stationary object
If the display shows all information at normal size, then the display region is efficiently used, but the user cannot confirm settings due to finger obstruction
Solution Approach 1:
The system prepares the enlarged display state in advance when touch is detected, before the user needs to confirm the setting. The operation detector triggers the enlargement action proactively when finger approach or contact is detected, ensuring the visibility improvement is available exactly when the user needs to confirm settings, without waiting for the confirmation moment.

AI summary
A vehicle display apparatus includes a display, a display processor, and an operation detector. The display processor is configured to cause the display to display a slider and a thumb. The operation detector is configured to detect touch of a finger on a display region of the display. When the operation detector continuously detects touch of the finger on a region where the slider is displayed for a first predetermined time or longer, the display processor is configured to cause the display to display an enlarged display image of the slider and the thumb. When the operation detector no longer detects touch of the finger after detecting touch of the finger for the first predetermined time or longer, the display processor is configured to cause the display to stop displaying the enlarged display image after a lapse of a second predetermined time.
