Wearable Optical Replicas for Driver Alertness Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current alertness monitoring systems in partially or fully automated vehicles are not flexible enough to allow temporary engagement in other activities during operation, leading to potential bypassing of safety measures, and there is a need for a method that does not permanently engage the monitoring systems but rather provides a temporary solution.
Innovation Solution
The method involves providing representations of facial features, such as eyes, that can be detected optically in the visible or infrared spectrum, which are worn like a pair of glasses and can simulate natural eye movements to avoid triggering alertness alarms, allowing the driver to perform other tasks temporarily without being detected as unalert.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If alertness monitoring systems continuously track driver behavior using cameras and sensors, then driver safety is improved, but driver freedom to perform temporary activities is reduced
Solution Approach 1:
The patent introduces an intermediary device (such as a wearable accessory or steering wheel attachment) that simulates alertness signals to the monitoring system. This intermediary acts as a mediator between the driver and the monitoring system, allowing the driver to perform temporary activities while the intermediary maintains the appearance of alertness by reflecting light or maintaining simulated contact patterns.
Solution Approach 2:
The patent employs copying by creating artificial representations of alertness indicators. The intermediary device replicates the optical or mechanical signals that indicate driver alertness, such as simulating eye reflection patterns or maintaining capacitive contact signals, thereby deceiving the monitoring system into believing the driver remains attentive.
2Measurement precision
If monitoring systems use hands-on detection with capacitive sensors, then detection precision is improved, but ease of operation is worsened due to restricted hand movements
Solution Approach 1:
The patent introduces an intermediary device placed between the driver's hand and the steering wheel that maintains continuous capacitive contact with the steering wheel while allowing the driver's hand to move freely. This intermediary acts as a mediator that preserves the electrical connection required for hands-on detection while eliminating the physical constraint on hand movement.
3Measurement precision
If camera systems monitor viewing behavior to detect alertness, then measurement precision is improved, but device complexity is increased
Solution Approach 1:
The patent employs copying by using simple reflective elements (such as colored stickers or coated surfaces) that replicate the optical properties of alert eyes. These reflective elements capture and redirect infrared or visible light in patterns that mimic natural eye reflection, providing a simple optical copy that deceives camera-based monitoring systems without requiring complex mechanical or electronic components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution effectively prevents the monitoring system from detecting genuine viewing behavior, ensuring that alertness alarms are not triggered, even if the driver is not actively looking at the road, thereby allowing temporary engagement in other activities while maintaining safety.
Implementation Method 1
providing representations of features, in particular of facial features, of a human person in a detection range of the system... which are worn like a pair of glasses and can simulate natural eye movements

AI summary
A method for influencing a system for monitoring alertness of an operator when operating a device includes providing one or more representations of features of the operator in a detection region of the system, where each of the one or more representations reproduces at least one feature of the operator and where the influencing is based on the detection of the one or more representations by the system.
