Rear-Seat Display Positioning Using Facial Area Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current in-vehicle infotainment systems lack precision in adjusting display positions, particularly for rear-seat users, leading to suboptimal viewing angles and decreased user experience due to limited manual adjustment capabilities.
Innovation Solution
A display adjustment method and apparatus that utilizes sensing information, such as data from cameras or radars, to determine the facial area of the target user and adjust the display's position accordingly, ensuring optimal viewing angles by aligning the display with the user's position and reference points, thereby improving adjustment precision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustment methods are used for display position, then the display can be adjusted, but the adjustment precision is low
Solution Approach 1:
The patent replaces manual mechanical adjustment with an automated sensing and control system. Sensors detect user position and facial area, and the system automatically adjusts display position based on detected data, eliminating the need for imprecise manual adjustment while maintaining ease of operation through automated control
Solution Approach 2:
The system performs self-adjustment by automatically detecting user position and facial area through sensors, calculating the optimal display position, and executing the adjustment without user intervention. This enables the system to serve itself in optimizing display positioning based on real-time user data
2Adaptability or versatility
If the display position is fixed, then the system structure is simple, but the viewing angle is not suitable for rear-seat users
Solution Approach 1:
The patent transforms the fixed display position into a dynamic, adjustable position. The display can move to different locations based on detected user position and facial area, allowing the system to adapt to various users and seating arrangements while maintaining a relatively simple overall structure through automated control mechanisms
3Measurement precision
If the display position is adjusted without sensing information, then the adjustment process is simple, but the adjustment precision is low
Solution Approach 1:
The patent introduces sensing information as an intermediary between the user and the display adjustment process. Sensors detect user position and facial area, providing precise data that enables accurate display positioning. This intermediary layer adds measurement precision while keeping the overall system complexity manageable through automated processing
Data Source
AI summary
This application discloses a display adjustment method and apparatus. One example method includes: A display adjustment apparatus may obtain sensing information, where the sensing information is used to determine a facial area of a target user. The display adjustment apparatus may further adjust, based on a position of the facial area, a position of a display corresponding to the target user, so that an adjusted position of the display is suitable for the user to view.
