Vehicle Display Touch Lockout Using Signal Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle-mounted display screens can affect driving safety by distracting drivers and causing body inclination during high-speed driving.
Innovation Solution
A display system with signal loading apparatuses and display screens that utilize a signal recognition module to detect specific signals, controlling the touch module's state based on detection results, thereby turning off the touch function when certain signals are detected to prevent driver interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a vehicle-mounted display screen is provided to satisfy user requirements for screen usage, then user convenience is improved, but driving safety deteriorates due to driver distraction and body inclination during high-speed driving
Solution Approach 1:
A signal recognition module is introduced as an intermediary between the touch module and the display screen. This module detects specific signals (such as heartbeat signals) to determine the driver's state, and automatically controls the touch module's working state accordingly. The intermediary mechanism resolves the contradiction by enabling automatic safety control without requiring manual driver intervention, thus maintaining user convenience while improving driving safety.
Solution Approach 2:
The display system performs self-service safety control by automatically detecting the driver's state through signal recognition and autonomously adjusting the touch module's working state. The system monitors physiological signals (e.g., heartbeat) and automatically disables or enables touch functionality based on detected conditions, eliminating the need for continuous manual monitoring and intervention by the driver.
2Ease of operation
If the touch module remains always active to allow user interaction, then ease of operation is improved, but harmful factors increase due to accidental touches during high-speed driving
Solution Approach 1:
The touch module's working state is made dynamic rather than static. The system automatically adjusts between different working states (enabled/disabled) based on real-time detection of specific signals. This dynamic adjustment allows the touch functionality to be available when safe while being automatically disabled when the driver's state indicates potential distraction or high-speed conditions, thus adapting to changing operational contexts.
Solution Approach 2:
A feedback mechanism is implemented where the signal recognition module continuously monitors for specific signals (such as heartbeat patterns) and provides feedback to the control module. Based on this feedback, the system automatically adjusts the touch module's state. The feedback loop enables the system to respond to driver physiological changes and environmental conditions, dynamically controlling touch functionality to prevent distraction while maintaining ease of operation when appropriate.
