Palm Recognition System for Vehicle Infotainment Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current infotainment systems in vehicles require drivers and passengers to physically interact with controls, leading to distraction and increased risk of accidents as drivers must look away from the road to operate the system.
Innovation Solution
An electronic system with palm recognition technology, comprising an image capturing unit, sensor unit, and processing unit that captures images, detects a palm within a sensing region, and stimulates applications on a display device without physical contact, allowing for hands-free operation and safer interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical contact controls are used for infotainment system operation, then ease of operation is improved, but driver safety deteriorates due to distraction and road attention loss
Solution Approach 1:
The patent replaces mechanical contact-based control systems with an optical sensing system that uses image capturing units and sensor units to detect palm gestures and features. This substitution eliminates the need for physical contact while maintaining operational capability, thereby improving driver safety without sacrificing ease of operation.
Solution Approach 2:
The patent introduces an intermediary optical sensing system that detects palm features and gestures as a mediator between the driver's intent and the infotainment system control. This intermediary allows the driver to operate the system without direct physical contact, reducing distraction while maintaining operational ease.
2Ease of operation
If physical contact controls are used, then ease of operation is improved, but distraction and road attention loss increase
Solution Approach 1:
The patent replaces mechanical contact-based controls with optical sensing technology that captures images and detects palm features from a distance. This allows drivers to operate the infotainment system without reaching forward or taking their eyes off the road for extended periods, thereby reducing road attention loss while maintaining operational ease.
Solution Approach 2:
The system performs preliminary detection of palm features and gestures before full system interaction is required. The sensor unit continuously monitors for palm presence and features, allowing the driver to initiate control without deliberate physical action, thus minimizing the time the driver's attention is diverted from the road.
3Reliability
If palm recognition technology is implemented, then driver safety is improved through hands-free operation, but device complexity increases
Solution Approach 1:
The patent implements a universal control system where a single palm recognition interface can operate multiple infotainment functions. The image capturing unit and sensor unit serve multiple purposes: detecting palm presence, recognizing palm features, identifying gestures, and triggering various system responses. This multi-functionality reduces the need for separate control mechanisms, thereby limiting the increase in device complexity.
Solution Approach 2:
The patent merges the image capturing unit, sensor unit, and processing functions into an integrated palm recognition system. By combining these elements into a unified control mechanism, the system achieves hands-free operation for improved safety while avoiding the complexity that would result from having separate systems for each function.
4Reliability
If palm recognition technology is implemented, then distraction is reduced through non-contact operation, but manufacturing complexity increases
Solution Approach 1:
The patent employs a universal palm recognition platform that can be integrated into various vehicle models and infotainment systems. The same image capturing unit and sensor unit configuration can serve multiple vehicle platforms, standardizing the manufacturing process and reducing the complexity increase that would otherwise result from custom implementations.
