Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Motion sickness occurs due to the discrepancy between visual and vestibular motion cues, particularly exacerbated by reading on electronic devices during transportation, leading to discomfort and potential severe symptoms.

Innovation Solution

An image display method and system that detects shock and speed information using detection units and adjusts the position of images on a display unit based on thresholds to alleviate motion sickness, utilizing horizontal and vertical shock detection and acceleration data to determine and compensate for motion-induced discomfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If images are displayed on electronic devices during transportation, then reading function is provided, but motion sickness occurs due to discrepancy between visual and vestibular motion cues

Engineering Contradiction:

Improvereading functionVSAvoidmotion sickness

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent detects shock and speed information using detection units, then uses this information to adjust image positioning to compensate for motion effects. The harmful motion cues are converted into useful positioning data that aligns visual display with vestibular perception, thereby eliminating motion sickness while maintaining reading functionality

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The patent dynamically changes the position parameter of displayed images based on detected shock and speed information. By adjusting image position in response to motion parameters, the system maintains visual-vestibular consistency and prevents motion sickness during transportation

Inventive Principle:

Principle #35Parameter changes

2Object-affected harmful factors

If image position is adjusted according to shock and speed information, then motion sickness is alleviated, but device complexity increases

Engineering Contradiction:

Improvemotion sicknessVSAvoiddetection unit and processing system

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical motion compensation systems with electronic detection and software-based image positioning. Detection units measure shock and speed, then processing units calculate and apply position adjustments digitally, simplifying the overall system while effectively alleviating motion sickness

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

The present disclosure provides an image display method and an image display system for alleviating motion sickness. The image display method includes: obtaining a number of shock and speed information of a transportation; comparing at least one of the shock and speed information with one or more than one corresponding threshold to determine whether motion sickness occurs; and in response to the determination that motion sickness occurs, positioning a position of a first image displayed on a display unit according to the shock and speed information.
