Vehicle Screen Mirror Image Activation via Face Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial vehicle drivers lack a convenient and easily usable mirror for tasks like shaving while on the road, as conventional mirrors are difficult to position and require adjustment, and existing solutions do not effectively integrate with vehicle displays.
Innovation Solution
A device with a screen and face detection system that displays a mirror image of the driver's face when predetermined criteria are met, such as facing the screen for a defined period and being in close range, ensuring the mirror image function is activated only when the vehicle is stationary, thereby enhancing the utility of the screen as a mirror without distracting the driver during movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate hand mirror is carried for shaving, then the driver can perform grooming tasks, but the mirror is difficult to position and requires holding with one hand
Solution Approach 1:
The patent combines the mirror function with the existing vehicle display screen by detecting the driver's face and displaying a mirror image on the screen. This eliminates the need for a separate hand mirror and integrates the grooming function into the vehicle's existing display system, making it easier to use while reducing device complexity.
Solution Approach 2:
The display screen is given multiple functions: it serves as both the original information display device and as a mirror when the driver's face is detected. This multi-functionality eliminates the need for additional dedicated mirror devices and maximizes the utility of existing components.
2Ease of operation
If the exterior mirror is used for shaving, then a mirror function is available, but the mirror must be regularly adjusted and the window opened
Solution Approach 1:
The mirror function is merged with the interior display screen, eliminating the need to use exterior mirrors and adjust windows. The driver can perform grooming tasks using the interior screen without any adjustment requirements, saving time and improving convenience.
3Ease of operation
If the mirror image function is always active on the screen, then the driver can use it conveniently, but the driver's attention may be distracted during movement
Solution Approach 1:
The mirror image function dynamically adjusts its availability based on vehicle motion state. The system detects whether the vehicle is stationary or moving and enables or disables the mirror function accordingly, ensuring safety during movement while maintaining convenience when parked.
Solution Approach 2:
The system uses feedback from motion detection to control the mirror image function. When motion is detected, the system provides feedback to disable the mirror function; when stationary, it enables the function. This feedback mechanism ensures safety while maintaining usability.
4Ease of operation
If a face detection device is added to enable automatic mirror image display, then the mirror function becomes more convenient, but the device complexity increases
Solution Approach 1:
The face detection device is integrated into the existing display system, and the same system components are used for multiple purposes: face detection for mirror activation, motion detection for safety control, and information display. This multi-functionality reduces the need for entirely separate systems and minimizes overall device complexity.

AI summary
The invention relates to a device for displaying information in a vehicle, particularly a commercial vehicle, comprising a screen (4) arranged in the vehicle (1), particularly in the driver's cab (3) of a commercial vehicle, by means of which information can be displayed visually. According to the invention, the screen (4) is associated with a device by means of which a face of a viewer looking at the screen (4), captured by at least one camera, can be displayed on the screen (4) in the manner of a mirror image. Particularly preferably, the screen (4) is associated with a face detection device (5) which is configured such that, when defined predefined criteria are met, it displays the face captured by at least one camera of the face detection device (5) on the screen (4) in the manner of a mirror image.
