Vehicle Display Control Device for Driver Interest Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display control systems for vehicles fail to effectively determine whether a driver is interested in information being output, as data is provided regardless of the driver's interest, leading to unclear engagement.
Innovation Solution
A display control device and method that acquires vehicle positional information and driver attribute information to derive relevant supply information, displaying a character on the vehicle's display that directs its sightline towards objects of interest, ensuring information is presented based on estimated driver interest.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If data of features is output regardless of driver interest, then information is provided to the driver, but it is unclear whether the driver is interested in the feature
Solution Approach 1:
The system uses eye tracking technology to detect the driver's gaze direction and determines whether the driver is looking at the same location as the character device. This feedback mechanism allows the system to adjust information output based on actual driver attention, resolving the contradiction by providing information only when the driver is interested.
Solution Approach 2:
The system changes the parameter of information output based on the detected driver gaze state. When conjugate gaze is detected (driver looking at same location as character), the system outputs feature data; when conjugate gaze is not detected, the system suppresses output. This dynamic parameter adjustment resolves the contradiction between information delivery and interest detection.
2Ease of operation
If information is supplied without considering driver attributes, then the system is simple to operate, but information relevance to driver interest is reduced
Solution Approach 1:
The system performs preliminary acquisition of driver attribute information (preferences, habits, characteristics) before information output. This advance preparation allows the system to filter and select features relevant to the specific driver, improving information relevance without complicating the actual operation during driving.
Solution Approach 2:
The system automatically utilizes detected driver attributes and gaze information to select and output relevant features without requiring driver input or configuration. This self-service approach maintains operational simplicity while improving information relevance through automatic adaptation to driver characteristics.

AI summary
A display control device configured to display an image on a display mounted on a vehicle, the display control device includes circuitry configured to: acquire positional information of the vehicle; derive supply information about an object around the vehicle based on attribute information of a driver of the vehicle and the positional information, the supply information being supplied to the driver; display a character on the display; cause an output device to output the supply information; and display the character directing a sightline toward the object on the display.
