Gaze Detection Visual Feedback for Calibration Transparency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current gaze detection systems for vehicles lack transparency in calibration status and accuracy, leading to driver anxiety due to unclear calibration results and potential false warnings, especially when new drivers are introduced.
Innovation Solution
A gaze detection apparatus and method that includes a display section to show a preset image indicating the gaze detection result at the intersection point between the driver's gaze and the display screen, along with an allowable error indication, allowing drivers to confirm detection accuracy and distinguish between calibration issues and system malfunctions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If calibration is performed automatically without driver awareness, then the calibration process can be completed, but the driver cannot determine whether calibration has been performed or recognize accuracy of gaze detection result
Solution Approach 1:
The patent displays a calibration status indicator on the display screen that provides visual feedback to the driver about whether calibration has been performed and the accuracy of gaze detection. This feedback mechanism resolves the contradiction by maintaining automatic calibration while informing the driver of the calibration status through visual indicators.
Solution Approach 2:
The patent introduces an intermediary visual indicator (calibration status indicator) that mediates between the automatic calibration system and the driver. This indicator serves as a communication bridge, conveying calibration status information without interrupting the automatic calibration process.
2Loss of information
If calibration is performed with driver awareness through displaying gaze image, then the driver can be aware of calibration, but the driver still cannot recognize accuracy of current gaze detection result
Solution Approach 1:
The patent implements a two-level feedback system: first, the calibration status indicator informs the driver whether calibration has been performed; second, the gaze detection accuracy indicator provides feedback on the precision of current gaze detection, allowing the driver to understand both the calibration status and the accuracy level.
Solution Approach 2:
The patent adds a new dimension of information display by introducing separate accuracy indicators that operate independently from the calibration status display. This dimensional separation allows simultaneous presentation of calibration status and accuracy information without confusion.
3Device complexity
If no visual feedback on gaze detection accuracy is provided, then the system remains simple, but the driver experiences anxiety and distrust toward detection results
Solution Approach 1:
The patent introduces visual feedback indicators that provide transparency into the gaze detection system's operation and accuracy. These indicators build driver trust by making the system's performance visible and understandable, resolving the contradiction between simplicity and reliability through informative rather than complex design.
Solution Approach 2:
The patent uses color-coded indicators (e.g., green for high accuracy, yellow for medium accuracy, red for low accuracy) to convey gaze detection accuracy levels. This color-based feedback system provides intuitive reliability information without adding significant complexity to the display interface.

AI summary
A gaze detection apparatus is disclosed. The gaze detection apparatus includes: a gaze detection section that detects gaze of a target person; a display section that includes a display screen for displaying an image; a gaze position determination section that determines, based on a result of detection by the gaze detection section, whether or not the display screen lies in the gaze of the target person; and a first display control section that displays a first detection result image at an intersection point between the gaze of the target person and the display screen when the first gaze position determination section determines that the display screen lies in the gaze of the target person.
