Vehicular Display Adaptation to Driver Line of Sight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicular display devices fail to adjust information display based on the driver's line of sight, leading to materialized information in peripheral visual fields and abstracted information in central visual fields, which can increase recognition time and information overload.
Innovation Solution
A method and device that use an integrated or external imaging device to detect the driver's line of sight and adjust the display form of information on a vehicular display device, displaying detailed information in the central visual field and abstracted information in the peripheral visual field, utilizing a processor to analyze images and determine visual field regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If materialized information is displayed on the display device in the peripheral visual field region, then the information can be displayed in detail, but the recognition time increases and information overload occurs
Solution Approach 1:
The patent applies local quality by displaying different types of information in different visual field regions. Specifically, materialized (detailed) information is displayed in the central visual field region where the driver can focus attention, while abstracted (simplified) information is displayed in the peripheral visual field region for quick glances. This spatial differentiation of information density resolves the contradiction between providing complete information and minimizing recognition time.
2Loss of time
If abstracted information is displayed on the display device in the central visual field region, then the recognition time is reduced, but the information needs of the driver are not fully satisfied
Solution Approach 1:
The patent implements local quality by adapting the information display format to the specific visual field region. In the central visual field region, the system displays materialized information with full details to satisfy the driver's information needs when they can dedicate attention. In the peripheral region, abstracted information is displayed for quick recognition during brief glances. This resolves the contradiction by matching information complexity to the driver's visual attention capacity in each region.
3Device complexity
If the display form of information is not changed in relation to the line of sight, then the display system is simple, but the information is not appropriately set in relation to the driver's visual field
Solution Approach 1:
The patent applies dynamics by making the display form adaptive rather than static. The system dynamically changes the display form (materialized vs. abstracted) based on the detected line of sight and the position of the display device within the driver's visual field. This dynamic adaptation enables the system to provide visually appropriate information without requiring multiple physical display devices, resolving the contradiction between system simplicity and visual field adaptability.

AI summary
A method of displaying information on a display unit (101) using a processor (110) configured to control a display device (100) to display the information. The display device (100) comprises the display unit (101). The method comprises imaging a user of the display device (100) using an imaging device (102) integrated with the display device (100), detecting a line of sight of the user from an image captured by the imaging device (102), determining whether the display unit (101) exists within a central visual field region (C) centered on the detected line of sight of the user or within a peripheral visual field region (P) located outside the central visual field region (C), displaying notification information on the display unit (101) in a first display form when the display unit (101) exists within the central visual field region (C), and displaying the notification information on the display unit (101) in a second display form when the display unit (101) exists within the peripheral visual field region (P). The second display form has a higher abstraction level than that in the first display form.
