Vehicle Display Gaze Control for Safer In-Car Video Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems struggle to effectively manage content playback and user interaction based on occupant behavior, such as gaze direction, voice activity, and seating status, leading to difficulties in meeting various needs related to external object identification.
Innovation Solution
A system that includes a vehicle display, processors recognizing behavioral information related to occupants, and a display controller that analyzes this information to control the display. The system determines when an occupant's gaze deviates from the display screen and adjusts the content playback or display settings accordingly, such as blurring the screen, pausing or lowering video volume, or displaying external interest information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the vehicle display continuously plays video content, then the entertainment function is improved, but the driver's attention may be diverted from the road
Solution Approach 1:
The system continuously monitors the driver's gaze direction using a gaze recognizer and provides feedback by adjusting video playback based on whether the driver is looking at the display or the road. When the driver's gaze is detected on the display, video playback continues; when gaze shifts to the road, playback is paused or stopped, thus adapting entertainment provision to driving safety conditions.
Solution Approach 2:
The video playback state is made dynamic rather than static, automatically transitioning between play, pause, and stop states based on real-time detection of driver behavior. This dynamic adjustment allows the system to adapt to changing driving conditions and driver attention levels, balancing entertainment needs with safety requirements.
2Reliability
If the system monitors driver gaze continuously, then driving safety is improved, but the device complexity increases
Solution Approach 1:
A gaze recognizer module is introduced as an intermediary component that specifically handles the complex task of eye tracking and gaze detection. This specialized module processes visual information and provides simplified gaze state outputs to the display controller, isolating the complexity of gaze monitoring from the overall display control system and making it more manageable and modular.
3Reliability
If the display blurs the screen when gaze deviates, then driving safety is improved, but the user experience deteriorates
Solution Approach 1:
Instead of completely stopping video playback when the driver looks away, the system applies a partial action by blurring the display content. This maintains the video playback state and audio output while reducing visual distraction, providing a compromise that preserves some user experience while still prioritizing driving safety. The blur effect is excessive enough to prevent detailed viewing but not enough to completely interrupt the entertainment flow.

AI summary
Disclosed is a system for controlling a vehicle display. The system includes a vehicle display, processors that recognize behavioral information related to an occupant in a vehicle viewing a display screen of the vehicle display, and a display controller that controls the vehicle display using the behavior information related to viewing the display screen. The display controller analyzes the behavior information related to viewing the display screen, determines when a gaze of the occupant deviates from an area of the display screen, and controls the vehicle display based on the gaze.
