Dynamic Vehicle Interface Adaptation for Driving Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle-mounted man-machine interfaces, such as CD/MD receivers, are difficult to operate while driving due to the need for precise visual attention, leading to potential mistakes and safety concerns, especially for individuals with poor eyesight or those needing to perform fine operations.
Innovation Solution
A vehicle-mounted man-machine interface device that dynamically adjusts the number and size of operating figures on the screen based on the vehicle's travel status, displaying larger and fewer figures when traveling to facilitate easier operation, and allows for user-specific customization and history-based settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple operating keys are displayed on the screen, then the functionality and versatility of the device is improved, but the visual complexity increases making it difficult to operate while driving
Solution Approach 1:
The operating screen dynamically changes its configuration based on vehicle travel status. When the vehicle is detected to be traveling, the system automatically adjusts the display to show fewer operating keys in larger sizes. When the vehicle is stopped, the system displays more operating keys in smaller sizes. This dynamic adaptation resolves the contradiction by making the interface simple during driving (improving ease of operation) while maintaining full functionality when stopped (improving versatility).
Solution Approach 2:
The system changes key display parameters (number of keys, size of keys) based on vehicle travel status. During travel, the parameters are adjusted to show fewer but larger keys for easy identification and operation. When stopped, the parameters return to showing more keys in smaller sizes. This parameter change strategy allows the same device to satisfy both contradictory requirements under different operating conditions.
2Ease of operation
If the operating keys are made larger, then the ease of operation is improved, but the number of keys that can be displayed simultaneously decreases
Solution Approach 1:
The operating screen dynamically adjusts the size and number of displayed keys based on vehicle travel status. During travel, keys are displayed larger with fewer keys visible to improve ease of operation. When stopped, the system switches to displaying more keys in smaller sizes. This dynamic adjustment resolves the contradiction by making key size adaptable to the operational context rather than fixed.
Solution Approach 2:
The operating interface is segmented into different display configurations based on travel status. The system divides the operating keys into different display groups - during travel, only essential keys are shown in larger sizes, while less critical keys can be accessed through additional screens or menus when stopped. This segmentation allows the interface to prioritize ease of operation during driving while maintaining access to all functions when stationary.
3Device complexity
If the operating keys are arranged in a fixed layout, then the device complexity is reduced, but the adaptability to different user needs and situations is worsened
Solution Approach 1:
The operating screen layout dynamically changes based on vehicle travel status rather than remaining fixed. During travel, the system automatically reconfigures the display to show fewer keys in larger sizes at optimized positions for quick access. When stopped, the system returns to the standard fixed layout with more keys. This dynamic reconfiguration maintains simplicity during driving while adapting to different operational requirements.
Solution Approach 2:
Different regions of the operating screen are assigned different qualities based on travel status. During travel, the interface prioritizes larger key sizes and simplified arrangement in the main display area, while secondary functions can be accessed through different menus or screens when stopped. This local quality adjustment allows the interface to be simple and adaptable during driving without sacrificing overall functionality.

AI summary
A vehicle-mounted man-machine interface device comprises display means for displaying a screen, press position detecting means for detecting the press position on the screen, and control means for displaying an operating screen on which operating figures are arranged on the display means and acquiring the operation content specified by the press on the operating screen from the arrangement positions of the operating figures, the operation on each operating figure, and the output of the press position detecting means. The device further comprises traveling detecting means for detecting whether or not the vehicle having the device is traveling or detecting the traveling speed of the vehicle. The control manes sets or alters one or both of the number of operating figures simultaneously displayed on the operating screen and their sizes according to the output from the traveling detecting means. With this, a man-machine interface technique for easily and reliably performing operation can be provided.
