Vehicle Display Pivoting for User Position Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle information display systems are not optimized for multiple users, as the same display settings may not be optimal for both the driver and passengers, leading to suboptimal information viewing experiences.
Innovation Solution
A method and device that detect the user's operating intention and relative position to pivot graphical objects in a three-dimensional perspective view, allowing each passenger to view a larger subset of information intuitively and rapidly, with the pivoting angle adjusted based on the user's viewing angle, distinguishing between the driver and passenger positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display shows a fixed subset of information optimized for one user position, then the information is clearly visible for that specific position, but other users at different positions cannot view the information optimally
Solution Approach 1:
The display system dynamically changes the presentation mode of information based on the detected position of the user. The control unit switches between first display mode (for distant viewing) and second display mode (for close interaction), making the display adaptive rather than static. This resolves the contradiction by allowing the same display to optimize for different user positions without requiring multiple physical displays.
Solution Approach 2:
The display system serves multiple functions: it can display information in a first mode optimized for users at a distance and in a second mode optimized for users close to the display. This multi-functionality allows a single display device to cater to different user needs and positions, improving adaptability without increasing the number of display devices.
2Loss of information
If the display area is kept small to reduce distraction for the driver, then driver safety is improved, but the total information quantity visible to passengers is limited
Solution Approach 1:
The information display is segmented into different presentation modes: a first display mode showing a subset of information for distant viewing (reducing driver distraction) and a second display mode showing comprehensive information for close viewing (preventing information loss). The system segments the information presentation based on user position and interaction intent, allowing both safety and information completeness to be achieved.
Solution Approach 2:
The display dynamically adjusts the amount and arrangement of information based on the user's position and operating intention. When the user is far from the display, only essential information is shown to minimize distraction. When the user approaches and interacts with the display, more comprehensive information becomes available, preventing information loss while maintaining safety during normal driving.
3Loss of information
If image scrolling is used to display more list entries, then the quantity of visible information increases, but the operating time required to access specific information increases
Solution Approach 1:
The system performs preliminary action by automatically switching to the second display mode when it detects that the user intends to interact with the display (through proximity detection or operating intention detection). This preliminary switch prepares the comprehensive information view in advance, so when the user wants to access specific information, it is already displayed and ready, eliminating the time loss that would occur with manual scrolling.
Solution Approach 2:
The system uses feedback from sensors to detect user proximity and operating intention, then automatically adjusts the display mode accordingly. This feedback mechanism ensures that the display provides the appropriate amount of information based on actual user needs, allowing quick access to comprehensive information when interaction is intended, while maintaining a simplified view when it is not.

AI summary
In a method for supplying a graphical user interface in a vehicle, at least one object for representing a first subset of total information is graphically displayed on a display area in at least one first display mode. An operating intention of a user is detected. In addition, a relative position of the user with respect to the display area is ascertained. When the operating intention of the user has been detected, the object is transferred into a second display mode, in which the object is displayed perspectively or three-dimensionally pivoted about an axis at a pivoting angle in the direction of the relative position. In addition, a device is adapted for providing a graphical user interface.
