Head-Mounted Display Testing With Simulated Ride Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted augmented reality/virtual reality displays used in amusement parks face durability challenges due to repeated use and exposure to ride motion stresses, leading to potential malfunctions and reduced lifespan.
Innovation Solution
A head-mounted display testing system that includes a ride motion simulator with a mount, cameras, and an actuator to simulate ride motion patterns, allowing for the detection of deviations in the display screen's image and assessment of display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If head-mounted displays are used during amusement rides, then the immersive experience for guests is enhanced, but the durability and lifespan of the displays are reduced due to repeated use and ride motion stresses
Solution Approach 1:
The system performs preliminary testing by simulating ride motion patterns on head-mounted displays before actual deployment. The ride motion simulator pre-exposes displays to controlled mechanical stresses, allowing identification of potential failure modes before the displays are used during actual amusement rides, thereby preventing field failures while maintaining ride immersion capabilities
2Measurement precision
If the head-mounted display is subjected to repeated ride motion stresses, then the display may show deviations from expected performance, but continuous monitoring and assessment require complex testing systems
Solution Approach 1:
The system uses cameras to capture images of the display screen during motion simulation, creating visual copies of the display output. These captured images are then analyzed to detect deviations from expected performance, replacing complex direct sensor measurements with simpler optical copying and image analysis techniques
3Reliability
If the ride motion simulator moves according to ride motion patterns, then the operational state of the display can be assessed under realistic conditions, but the testing process requires precise control and coordination of multiple components
Solution Approach 1:
The ride motion simulator serves multiple functions: it acts as both the test subject platform and the testing environment. The same simulator that will eventually carry guests on amusement rides is used to test the head-mounted displays, allowing simultaneous assessment of display durability under realistic ride conditions while using existing infrastructure rather than requiring separate specialized test equipment

AI summary
A head-mounted display testing system may include a ride motion simulator to simulate a movement of an amusement ride and a head-mounted display mounted on the ride motion simulator that displays a virtual image. The ride motion simulator includes one or more outward facing cameras configured to capture the virtual image and a physical marker when the head-mounted display is on the ride motion simulator. The controller is configured to receive the footage of the head-mounted display screen captured by the one or more cameras and to generate an indication of head-mounted display quality based on deviations from an expected display.
