Vehicular Display Mode Transition Animation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicular display devices do not effectively match mode transitions with the user's sense, making it difficult for users to visually confirm that their operating inputs have been correctly reflected during mode changes.
Innovation Solution
A vehicular display device and method that includes an image display device in front of the driver, displaying information images based on selected modes, with a menu image showing titles in a lateral direction, and performing animation displays to change the active title from the previous mode to the new mode when switching modes, even when the menu image is hidden.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the menu image is hidden to reduce information clutter, then visibility of necessary information is improved, but user confirmation of mode transition becomes difficult
Solution Approach 1:
The display information is segmented into essential information (displayed continuously) and supplementary information (menu image, displayed on demand). This segmentation allows the system to maintain clear visibility of necessary information while providing transition confirmation when needed, resolving the contradiction between information clarity and transition visibility.
Solution Approach 2:
The menu image is displayed in advance before mode transition completes, showing the target mode's information preliminarily. This preliminary display allows users to confirm the transition before it fully executes, addressing the need for transition confirmation without permanently cluttering the display.
2Ease of operation
If animation display is added to show mode transitions, then user sense of mode change is improved, but device complexity increases
Solution Approach 1:
The display system dynamically adjusts between static information display and animated transition display based on operational state. The animation is activated only during mode transitions, providing intuitive visual feedback without requiring permanently complex animation mechanisms, thus improving ease of operation without excessive complexity.
Solution Approach 2:
The animation display operates periodically only during mode transition events rather than continuously. This periodic activation provides necessary transition feedback while minimizing the overall complexity burden, as the animation system remains dormant during normal operation and is activated only when needed.

AI summary
A vehicular display device includes an image display device that is arranged in front of a driver in a vehicle and configured to display an image. The image displayed in an information display area of the image display device includes an information image displaying information according to a mode selected out of a plurality of modes, and a menu image in which a plurality of titles corresponding to the respective modes are arranged in a lateral direction of the image and for which switching is made between display and hidden-display. When an operating input to switch the modes is made while the menu image is hidden, the image display device displays the menu image, and performs animation display that changes a title displayed as active out of the titles from a title corresponding to a mode before change to a title corresponding to a mode after the change.
