Vehicle Display Area Selection for Motion Sickness Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In autonomously or partially autonomously operable motor vehicles, drivers in non-traditional seating positions face conflicts between visual perception and balance, leading to discomfort and nausea due to inadequate information display.
Innovation Solution
A method for selecting an optimal display area based on the vehicle's configuration, using adjustable seating settings to direct the driver's view towards a headliner display, which can show driving status information from cameras and other sources, allowing contact-free control via gestures and sensors to monitor driver condition and adjust the display accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the driver adopts a non-traditional seating position (leaning back or rotating seat) in autonomous mode, then the driver can relax and create a seating group, but the driver experiences conflict between visual perception and balance leading to discomfort and nausea
Solution Approach 1:
The patent introduces an intermediary display system (head-up display or dashboard display) that mediates between the driver's relaxed seating position and the need for visual balance information. The display provides compensatory visual cues about vehicle motion and orientation, allowing the driver to relax without experiencing motion sickness from sensory conflict.
Solution Approach 2:
The system provides real-time feedback to the driver about vehicle status, position, and motion through the display. This feedback loop allows the driver's relaxed position to be maintained while keeping them informed about the vehicle's state, preventing the sensory disorientation that causes motion sickness.
2Loss of information
If information is displayed on traditional dashboard screens, then the driver can access driving status information, but the display is not optimized for relaxed seating positions where the driver's view is directed away from the front
Solution Approach 1:
The patent transitions from traditional horizontal dashboard displays to a head-up display projected on the windshield or a vertically oriented display, changing the spatial dimension of information presentation. This allows information to be accessible to drivers in relaxed positions where their line of sight is directed away from the traditional dashboard area.
Solution Approach 2:
The display system is designed to serve multiple functions and multiple seating configurations. It can provide driving status information, navigation, entertainment, and vehicle control interfaces in a single unified system that adapts to both traditional and relaxed seating positions, eliminating the need for separate display solutions.
3Adaptability or versatility
If multiple display areas are available for information presentation, then the system can adapt to different seating positions, but the complexity of selecting the optimal display area increases
Solution Approach 1:
The system automatically detects the driver's seating position and autonomously selects the optimal display area without requiring manual input from the driver. Sensors detect seat position, backrest angle, and steering wheel position to determine the best display configuration, eliminating the complexity of manual display selection while maintaining high adaptability.
Solution Approach 2:
The display system dynamically adjusts its configuration based on real-time detection of seating position and driving mode. The display area, orientation, and content are automatically optimized for the current configuration, allowing the system to adapt to different seating positions without requiring complex manual selection procedures.
