Smart Ring Projection for In-View Driving Condition Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle information systems provide limited information to drivers, often requiring them to take their hands off the wheel or divert their gaze, increasing the risk of hazardous driving.
Innovation Solution
A smart ring device that projects driving conditions, including biometric data and environmental information, directly onto a surface within the driver's field of view, allowing hands-free and gaze-free access to vital vehicle and environmental data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a central console display is used to provide driving information, then information can be presented to the driver, but the driver must shift gaze away from the road, increasing hazardous driving risk
Solution Approach 1:
A camera positioned in the vehicle captures images of the road and surrounding environment, serving as an intermediary to transfer visual information to the driver's field of view without requiring the driver to shift gaze. The camera system mediates between the external environment and the driver's perception, allowing continuous road monitoring while receiving driving condition information.
Solution Approach 2:
The system transitions information delivery from a centralized console location to a distributed projection across the driver's field of view. By projecting information onto surfaces within the driver's natural viewing area (such as the windshield or dashboard surfaces), the system changes the spatial dimension of information presentation, allowing drivers to access driving condition data without altering their gaze direction.
2Loss of information
If a projector module is integrated into the smart ring, then comprehensive driving information can be displayed in the driver's field of view, but the device complexity increases
Solution Approach 1:
The smart ring device integrates multiple functions into a single component: biometric sensing (heart rate, stress detection), communication (receiving driving condition data from external sources), and visual projection (displaying information in the driver's field of view). This multi-functionality reduces the need for separate devices while managing complexity through consolidation of essential features.
Solution Approach 2:
The smart ring acts as an intermediary device that receives driving condition information from external communication sources and biometric data from integrated sensors, then projects this combined information into the driver's field of view. Rather than requiring a complex integrated system in the vehicle, the smart ring mediates between external information sources and the driver, simplifying the overall system architecture.
3Measurement precision
If biometric sensors are integrated into the smart ring, then driver operational state can be monitored, but the device complexity and power requirements increase
Solution Approach 1:
The smart ring utilizes thin-film biometric sensors integrated into the flexible ring structure. These thin-film sensors can detect biometric parameters (such as heart rate and stress levels) through contact with the driver's finger, providing precise monitoring capability while maintaining a compact, low-profile device design that minimizes complexity compared to bulkier sensor arrangements.
