Vehicle Operating Device Dynamic Display State Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In vehicles, existing systems fail to display information in a way that is both intuitive and non-distracting for drivers, making it difficult for them to quickly grasp and operate displayed information without taking their eyes off the road.
Innovation Solution
A method and operating device that automatically change the display state from a non-operational to an operational mode upon detection of an actuation object, converting display elements into buttons by altering their appearance such as brightness, contrast, color, or adding borders, while keeping additional information unchanged, allowing drivers to easily identify and interact with operational elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a large amount of information is displayed on the display area, then the information completeness is improved, but the driver's ability to quickly grasp and operate the information is worsened
Solution Approach 1:
The display area is segmented into different functional zones: a first display area for information requiring driver operation (displaying buttons with higher brightness) and a second display area for information not requiring operation (displaying display elements with lower brightness). This segmentation allows the system to present comprehensive information while guiding the driver's attention to only the interactive elements, thus maintaining both information completeness and operational efficiency
Solution Approach 2:
Different display elements are assigned different visual properties based on their functional requirements. Buttons in the first display area are displayed with higher brightness to indicate interactivity, while display elements in the second area use lower brightness. This local differentiation of visual quality enables drivers to quickly identify operational elements without being overwhelmed by the entire information set
2Ease of operation
If display elements are made visually prominent to improve identifiability, then the ease of operation is improved, but the driver distraction is worsened
Solution Approach 1:
Instead of making the entire display visually prominent, the system applies enhanced visual properties (higher brightness) only to buttons in the first display area that require driver operation. Display elements in the second area maintain lower brightness. This localized visual enhancement improves button identifiability while minimizing overall driver distraction by keeping non-interactive information less conspicuous
Solution Approach 2:
The display is divided into two distinct areas with different visual characteristics. The first display area segments interactive buttons that need to stand out for operational efficiency, while the second area segments non-interactive information that can be less prominent. This segmentation resolves the contradiction by allowing visual prominence only where necessary for operation

AI summary
The present invention relates to a method for producing an operating device (6) in a vehicle (11), wherein graphic data are generated by a control device (3), which actuate a display area (2) such that, in an operating state, control buttons (13b) are displayed that are assigned to an operating step which can be executed by means of the input device (4), and that, in a display state, display elements (13a) that are assigned to the control buttons (13b) are displayed, which are not assigned to an operating step which can be executed by means of the input device (4), and that, in the display and operating state, additional information is displayed separately from the display elements (13a) and the control buttons (13b). Additionally, an approach of an object to the input device (4) is detected and, when an actuation object (12) approaches the input device (4), the control device (3) switches from the display state into the operating state. The method as per the invention is characterised in that, when there is a change from the display state into the operating state, the display mode of the display elements (13a) switches to a display mode of the control buttons (13b), whereas the display of the additional information remains unchanged. The invention further relates to an operating device (6) for executing this method and a vehicle (37) comprising an operating device (6) of this kind.
