Driver Attention Feedback for In-Vehicle Display Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display control methods for vehicles struggle to appropriately display information to drivers, leading to inefficient transmission of driving assistance information.
Innovation Solution
A display control method that acquires a first image of a driver's field of view, generates a second image by adding a display object to a predetermined display area, estimates the driver's attention state using attention estimation models, and adjusts the display form of the display object based on the estimated attention state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a display object is added to the display area in the driver's field of view, then driving assistance information can be transmitted to the driver, but the driver's attention may be excessively focused on the display object, causing distraction
Solution Approach 1:
The system continuously monitors the driver's attention state through image acquisition and attention estimation models, and uses this feedback to dynamically adjust the display form of the display object. When the driver's attention is estimated to be excessively focused on the display object, the system automatically adjusts display parameters such as brightness, size, or position to reduce attention concentration, thereby preventing distraction while maintaining effective information transmission.
2Reliability
If the display form of the display object is adjusted to capture driver's attention, then information transmission effectiveness is improved, but the complexity of the display control system increases
Solution Approach 1:
The system introduces an attention estimation model as an intermediary between the display object and the driver's attention state. This model processes image data and provides estimates of the driver's attention state, which then guides the adjustment of display parameters. By using this intermediary, the system achieves effective information transmission with automated control, reducing the need for complex manual control mechanisms while maintaining reliability.

AI summary
A display control method according to the present disclosure includes: acquiring a first image corresponding to a field of view of a driver in a vehicle interior including a display area; generating a second image by adding, in a first display form, a display object by a display to the display area in the first image; estimating an attention state of the driver by applying one or more attention estimation models to the second image; and controlling a display form of the display object to be displayed by the display in the display area in the vehicle interior, depending on an estimation result of the attention state.
