In-Display Hand Position Sensing for Driver Menu Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current autonomous driving technologies require manual driver intervention to respond to road signs, leading to driver distraction and increased unexpected accidents, especially in conditions like freezing weather or falling stones, due to the lack of automated vehicle control systems.
Innovation Solution
An autonomous driving system that uses sensors and cameras to recognize road signs and environmental conditions, automatically adjusting vehicle settings such as transmission gears, sunroof operation, and speed to maintain optimal driving conditions, and includes a sensor unit with light emitting and receiving capabilities to detect user hand positions for intuitive menu selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual driver response to road signs is required, then driver control and vehicle safety are maintained, but driver distraction increases and unexpected accidents occur
Solution Approach 1:
The system enables the vehicle to automatically respond to road signs and environmental hazards without requiring manual driver intervention. The controller autonomously adjusts transmission gears, closes sunroofs, and controls vehicle speed based on sensor inputs, allowing the vehicle to serve itself in hazardous conditions
Solution Approach 2:
The system performs preliminary actions by detecting road signs and environmental conditions in advance and automatically preparing the vehicle for potential hazards. For example, it preemptively adjusts transmission gears when freezing signs are detected, or closes sunroofs when falling stone warnings are received, before the driver can manually respond
2Ease of operation
If traditional sensor placement is used, then manufacturing simplicity is maintained, but user interaction and menu selection convenience are reduced
Solution Approach 1:
The system transitions from traditional horizontal sensor placement to a vertical arrangement where the sensor unit is positioned below the display unit. This dimensional change enables the sensor to detect hand positions from underneath the display, creating intuitive gesture-based menu selection zones without requiring complex lateral sensor configurations
