Vehicle Display Position Estimation Using Driver Face Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicular display devices struggle to adapt to arbitrary locations in front of the driver, as they are typically set relative to a predetermined installation location, limiting their ability to respond to varying positions of the mobile terminal.
Innovation Solution
The system determines the image data to be displayed based on the estimated installation location of the information processing device using a combination of face position detection from a first image and distance information from a second image, allowing for dynamic adjustment of the display content according to the device's location.

1Adaptability or versatility
If the reference position is set with respect to a predetermined installation location of the mobile terminal, then the display control can be simplified, but the system cannot respond to situations where the mobile terminal is disposed at an arbitrary location
Solution Approach 1:
The system performs preliminary actions by capturing images and estimating the installation location before displaying content. The processor captures a first image to detect the driver's face position and captures a second image to detect distance information before determining the final display parameters, allowing the system to adapt to arbitrary locations without requiring complex real-time adjustments during content display
Solution Approach 2:
The patent introduces an intermediary location estimation mechanism that uses face position detection from a first image and distance information from a second image as intermediate steps. This intermediary process translates arbitrary physical locations into standardized display parameters, enabling the system to handle arbitrary installations without directly complex control logic

AI summary
A method of estimating the location of a display device (100) using a processor (110) is provided. The display device (100) includes a display unit (101) configured to display information and is disposed in front of the driver's seat in a vehicle. The method includes imaging the driver's face using a first imaging device (102) provided on a surface of the terminal device on which the display unit (101) of the display device (100) is provided and estimating the location of the display device (100) on the basis of the direction of the driver's face imaged by the first imaging device (102).
