Vehicle Display Adaptation Based on User Action Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems, particularly those using data glasses or helmets, fail to account for the user's surroundings during operations, leading to potential injuries or disturbances due to unaware movements.
Innovation Solution
A display system with a recognition unit to determine the user's sitting position and available action space, adapting output image content and action radius to prevent collisions or disturbances by using input units like joysticks or gestures, and integrating sensors for further occupant, vehicle, and user property recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If AR/VR display systems are used to provide interactive image contents, then the user experience and engagement are improved, but the user may bump into vehicle doors or touch passengers due to uncontrolled movements
Solution Approach 1:
The system performs preliminary detection of the user's sitting position and available action space before allowing interactive operations. The recognition unit identifies the user's location and the processing unit determines safe movement boundaries in advance, preventing harmful movements before they occur.
Solution Approach 2:
The action space is dynamically adjusted based on the user's sitting position, vehicle type, and detected occupants. The processing unit continuously adapts the available action radius to match the current spatial conditions, ensuring safety while maximizing interactive freedom.
2Ease of operation
If the action radius is increased to enhance gaming experience, then the user can perform more operations, but the risk of disturbing or injuring others increases
Solution Approach 1:
The system uses feedback from the recognition unit about user position and vehicle occupancy to continuously adjust the permissible action radius. The processing unit receives real-time information about the user's location and modifies the action space boundaries to prevent harmful operations while allowing safe interactions.
Solution Approach 2:
The system changes the parameter of action radius based on detected conditions such as user sitting position, vehicle type, and presence of other occupants. The processing unit adapts the action space parameters dynamically to balance gaming freedom with safety constraints.
3Reliability
If the display system adapts image content based on sitting position, then safety is improved, but the system complexity increases due to additional recognition and processing requirements
Solution Approach 1:
The recognition unit and processing unit serve multiple functions: detecting user position, identifying vehicle type, determining available action space, and adapting image content. By making these components multi-functional, the system achieves high safety reliability without proportionally increasing overall complexity.
Solution Approach 2:
The display system automatically detects user position and adapts content without requiring manual input from the user. The recognition unit and processing unit work autonomously to ensure safety, reducing the need for additional control interfaces or user actions.

AI summary
A display system for a vehicle includes an output unit for displaying image content for a user, an input unit for inputting operator control actions for the image content, a detection unit which is configured to detect a sitting position of the user in the vehicle, and a processing device which is configured to determine an available action space on the basis of the sitting position and to adapt the image content to be output and/or the action radius of the user on the basis of the available action space.
