Mobile Sensor Apparatus for Head-Worn Display Simulator Sickness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of immersive technologies like virtual reality glasses in vehicles can lead to 'simulator sickness' due to inconsistencies between sensory impressions of body movement and visual perception, as the content displayed does not align with the vehicle's movement, causing discomfort or nausea in occupants.
Innovation Solution
A mobile sensor apparatus that detects vehicle movements and transmits this data to a head-worn visual output device, allowing it to display corresponding structures in a peripheral area, thereby aligning visual and sensory inputs and reducing the risk of simulator sickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If immersive technologies like virtual reality glasses are used in vehicles to display media content, then entertainment value and user engagement are improved, but simulator sickness occurs due to inconsistencies between visual perception and body movement sensing
Solution Approach 1:
The patent applies feedback by continuously detecting vehicle movement data via sensors (accelerometers, gyroscopes, GPS) and transmitting this information to the head-worn display device. The display then adjusts the presented content based on this feedback, synchronizing visual elements with actual vehicle motion to eliminate the sensory conflict that causes simulator sickness.
Solution Approach 2:
The patent introduces a mobile sensor apparatus as an intermediary component that bridges the vehicle's movement characteristics and the head-worn display device. This intermediary collects movement data, processes it, and transmits it to the display, enabling the display to adapt its content presentation based on real-world vehicle motion without requiring direct integration with the vehicle's control systems.
2Object-affected harmful factors
If a mobile sensor apparatus is introduced to detect vehicle movements and transmit data to the head-worn device, then simulator sickness is reduced, but device complexity increases
Solution Approach 1:
The mobile sensor apparatus is designed as a universal, multi-functional device that can detect various types of vehicle movements (acceleration, rotation, position) and interface with different head-worn display devices. This universal design reduces overall system complexity by using a single versatile component rather than multiple specialized sensors for each function.
Solution Approach 2:
The mobile sensor apparatus serves as a standalone intermediary that handles all sensor detection, data processing, and transmission functions externally. This approach prevents the complexity of sensor integration from being incorporated into the head-worn display device itself, keeping the wearable device simple while the separate sensor apparatus manages the complexity of movement detection and data management.
