Electronic Mirror Driver Eye Tracking Notification Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic mirror systems in vehicles often display notifications and warnings across multiple displays, which can lead to drivers overlooking important events or being irritated by excessive alerts, as the notifications may not be visible when the driver is not looking at the correct display, and the system's brightness may not adapt to dark environments effectively.
Innovation Solution
An apparatus that combines electronic mirror systems with driver monitoring, using an interface and processor to detect the driver's eye position and adjust content presentation, suppress notifications when the driver is not looking at the relevant display, and adapt brightness based on the driver's gaze direction, implementing computer vision for internal and external object detection and alerting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If notifications are displayed on multiple displays simultaneously, then the driver can see notifications on any display, but the driver may overlook important events or be irritated by excessive alerts when not looking at the correct display
Solution Approach 1:
The system continuously monitors driver eye position through capture devices and uses this feedback to dynamically control notification display behavior. The processor detects whether the driver is looking at a specific display and adjusts notification presentation accordingly, creating a closed-loop system that adapts to driver attention state
Solution Approach 2:
The notification display system transitions from a static approach (always displaying on all displays) to a dynamic approach where display selection and notification behavior change based on real-time driver eye position detection. The system adapts its behavior continuously as the driver moves their gaze between displays and the road
2Reliability
If the e-mirror display is active all the time to replace reflective mirrors, then the driver can see through the display, but the display brightness may not adapt to dark environments effectively
Solution Approach 1:
The system uses capture devices to detect driver eye position and environmental conditions, then feeds this information back to adjust display brightness dynamically. The processor monitors whether the driver is looking at the display and adapts brightness levels accordingly, creating adaptive illumination that responds to real-time conditions
Solution Approach 2:
The display brightness parameter is changed dynamically based on detected environmental conditions and driver attention state. The system adjusts illumination intensity to be higher when the driver is looking at the display during daytime, and adapts brightness for dark environments when appropriate, optimizing visibility while reducing glare
3Adaptability or versatility
If multiple displays are used for e-mirror and notifications, then the system provides comprehensive information, but the complexity of the system increases
Solution Approach 1:
The capture devices and processor serve multiple functions: they detect driver eye position for both notification control and brightness adaptation, monitor driver attention for safety purposes, and provide the basis for dynamic display management. This multi-functionality reduces the need for separate dedicated components for each function
Solution Approach 2:
The system merges the electronic mirror display function with notification display capability and driver monitoring function into an integrated system. The same display hardware and processing resources are used for multiple purposes, reducing overall system complexity while maintaining comprehensive functionality

AI summary
An apparatus includes an interface and a processor. The interface may be configured to communicate video data to a display. The processor may be configured to receive video frames from a capture device, generate video data for the display in response to the video frames, perform operations to detect an object in the video frames and determine eye position information. The eye position information may be used to determine whether a driver is looking at the display. The processor may be configured to adjust content presented by the display when the driver is looking at the display.
