Solution Overview

Problem

Motion sickness in vehicle passengers is exacerbated when they look at stationary objects within the vehicle during acceleration, deceleration, or changes in direction, as existing methods fail to provide an effective correlation between vehicle acceleration and displayed information.

Innovation Solution

A method and system that display information related to the status of acceleration or deceleration control devices, such as the accelerator or brake pedal, and a top view representation of the road, using sensors to provide real-time acceleration data, allowing for improved correlation with the displayed content on a display device, including personal mobile devices, to simulate the vehicle's acceleration and anticipate upcoming movements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a display device shows stationary content to passengers, then the display device can provide entertainment or information, but the passenger experiences motion sickness during vehicle acceleration

Engineering Contradiction:
Improvedisplay functionalityVSAvoidmotion sickness
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The displayed content is dynamically adjusted to match the vehicle's acceleration state. The display transitions from static to dynamic content that moves in correlation with vehicle acceleration, maintaining visual stability relative to the passenger's perceived motion and preventing motion sickness while preserving entertainment functionality.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The display parameters (position, speed, orientation of displayed objects) are changed in real-time based on vehicle acceleration data. By modifying these parameters to correlate with actual vehicle motion, the display creates a visually stable experience that prevents motion sickness while maintaining versatile display capabilities.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If the display device shows content that does not correlate with vehicle acceleration, then the display device can show any information, but the correlation between acceleration and displayed information is poor

Engineering Contradiction:
Improvedisplay content flexibilityVSAvoidacceleration correlation
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The system continuously receives feedback from vehicle acceleration sensors and adjusts the displayed content parameters in real-time. This feedback loop ensures that the displayed information accurately correlates with the vehicle's actual acceleration state, improving measurement precision while maintaining content flexibility through dynamic adjustment.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The display content transitions from static to dynamic, with motion parameters that mirror vehicle acceleration. This dynamic correlation ensures that whatever content is displayed (entertainment, information, etc.) maintains accurate acceleration correlation, resolving the contradiction between content flexibility and measurement precision.

Inventive Principle:
Principle #15Dynamics

3Productivity

If the display device uses a delay between acceleration detection and content adjustment, then the system can process information, but the correlation between acceleration and displayed content is reduced

Engineering Contradiction:
Improveinformation processingVSAvoidacceleration correlation
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The system performs preliminary processing of acceleration data and prepares display content adjustments in advance, using buffered sensor data and pre-computed transformation parameters. This allows rapid response with minimal delay, maintaining high acceleration correlation while ensuring thorough information processing through advance preparation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system maintains continuous processing of acceleration data and continuous adjustment of display content without interruption or significant delay. This uninterrupted workflow ensures both high productivity in information processing and high measurement precision in acceleration correlation by keeping the feedback loop continuously active.

Inventive Principle:
Principle #20Continuity of useful action

AI summary

A method of operating a display device in or on a vehicle for road use is disclosed. The display device is a display device which is different from a display device - for providing information to a driver of the vehicle and - which forms part of, or is proprietary to, the vehicle. The method comprises displaying, on the display device, - information relating to, or derived from, a status of an acceleration or deceleration control device, in particular a status of an accelerator pedal or brake pedal, in particular a position of the acceleration or deceleration control device, in particular a position of the accelerator pedal or brake pedal, and/or - a top view representation of a portion of a road on which the vehicle is travelling.
