Vehicle Camera Cleaning Notification Using Driver Gaze Priority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning notification systems for imaging devices on vehicles may fail to ensure that users comprehend cleaning has been implemented, especially when notifications are limited or coincide with other notifications.
Innovation Solution
A cleaning notification device that detects the user's line of sight and raises the priority level of the notification when the user is looking at a display device, ensuring the notification is easily understood by adjusting priority levels based on user attention and notification conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the display region for notification is limited or notification timing coincides with other notifications, then the notification system can maintain simple display structure and avoid excessive notification frequency, but the user comprehension of cleaning notification deteriorates
Solution Approach 1:
The notification system dynamically adjusts the priority level of cleaning notifications based on real-time detection of user line of sight. When the user is detected to be looking at the display device, the system raises the priority level of cleaning notifications, ensuring they are prominently displayed and not obscured by other notifications. This dynamic adjustment resolves the contradiction by maintaining simple notification structure while ensuring user comprehension through context-aware priority management.
2Loss of information
If the priority level of cleaning notification is raised when user is looking at display device, then user comprehension of cleaning notification is improved, but the notification system complexity increases due to line of sight detection and priority management
Solution Approach 1:
The system introduces a line of sight detection unit as an intermediary component that monitors user attention state and communicates this information to the notification control unit. This intermediary enables the system to adjust notification priorities based on user engagement without requiring complex integrated processing, thereby improving user comprehension while managing system complexity through modular functional separation.
Solution Approach 2:
The notification system changes the priority level parameter of cleaning notifications based on detected user line of sight conditions. When the user is detected to be looking at the display device, the system transitions the notification priority from a normal level to a high priority level, ensuring the notification is prominently displayed. This parameter change approach allows flexible adaptation to user state without restructuring the entire notification system.
3Reliability
If notification timing is adjusted based on user line of sight, then notification delivery effectiveness is improved, but the system complexity increases due to continuous line of sight monitoring
Solution Approach 1:
The system performs preliminary line of sight detection to determine user attention state before delivering the cleaning notification. By detecting whether the user is looking at the display device in advance, the system can proactively adjust the notification priority level, ensuring effective delivery. This preliminary action approach improves notification reliability while avoiding the need for continuous monitoring during the entire notification period.

AI summary
There is provided a cleaning notification device including: a detection unit which, in a case where cleaning of an imaging device that is installed on a vehicle and captures images of the environment external to the vehicle has been performed, detects the line of sight of a user riding in the vehicle; and a processing unit which, in a case where the user is looking at a first display device that displays captured images that have been captured by the imaging device, executes a process relating to an implementation notification indicating that cleaning of the imaging device has been implemented.
