Touch Display Control Layout Based on Vehicle User Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch-sensitive display systems in vehicles often fail to optimally arrange control areas for multiple users, leading to discomfort and inefficient use of screen space, as some users may struggle to reach or operate necessary functions.
Innovation Solution
A method that determines the relative position of users in relation to the display device and assigns and arranges control areas based on user position, adapting their size and visibility to user needs and permissions, using existing vehicle sensors like cameras and seat occupancy sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If control areas are arranged in a fixed layout on the display, then the display structure is simple and easy to manufacture, but users at different positions cannot comfortably access all control areas
Solution Approach 1:
The control area arrangement is made dynamic rather than static. The system continuously determines user positions using sensor data (camera, seat sensors) and automatically rearranges control areas on the display in real-time. This dynamic adaptation ensures that control areas are always positioned within comfortable reach of the current user, resolving the contradiction between ease of operation and device complexity.
Solution Approach 2:
Different control areas are assigned to different spatial zones on the display based on user position. The system identifies which user is seated where and presents relevant control areas in their local field of view and reach zone. This local quality approach ensures each user sees and can access the control areas most relevant to their position, improving accessibility without requiring a completely complex system redesign.
2Adaptability or versatility
If the display shows all control areas for all possible functions, then all functions are accessible, but screen space is wasted and energy consumption increases
Solution Approach 1:
The system extracts and displays only the control areas that are relevant to the current user's position and needs, rather than showing all possible control areas. By using sensor data to determine which user is seated where, the system selectively presents only the necessary control functions, reducing screen content while maintaining full functionality. This extraction principle reduces energy consumption by displaying fewer elements while preserving adaptability.
Solution Approach 2:
The system changes the parameter of display content based on user position. When a user is detected in a specific seat, the display parameters (which control areas are shown, their size, and position) are adjusted to match that user's needs. This parameter change approach allows the same display hardware to serve multiple users efficiently, reducing energy waste by not continuously displaying all possible control areas.
3Ease of operation
If control areas are made larger for easier operation, then ease of operation improves, but fewer control areas can be displayed on the screen
Solution Approach 1:
The size of control areas is made dynamic rather than fixed. The system adjusts control area dimensions based on the current user's position, reach capability, and the number of relevant control functions needed. When fewer control areas are needed, they can be displayed larger for easier operation. When more control areas are needed, the system can display them in a grid layout with smaller individual areas. This dynamic sizing resolves the contradiction between operability and screen space utilization.

AI summary
A method operates a touch-sensitive display device designed for displaying at least two control areas. The method includes determining at least one relative position of at least a first user of a set of users comprising one or more users in relation to the display device. The method also includes assigning at least one of the at least two control areas to the first user. The method further includes arranging the at least two control areas on the display device on the basis of the assignment to the first user and the relative position of the first user in relation to the display device.
