This case study explores the role of IMU-based motion capture in assessing comfort and safety in amusement rides, suggesting improvements in evaluation methods.
The design and assessment of amusement rides and devices require consideration of human interaction, movement, and performance throughout the process. Traditional assessment methods for evaluating amusement rides (i.e., roller coasters) involve a single sensor measuring accelerations, aiming to evaluate the instantaneous and sustained accelerations (g) of the rider as indicators of patron safety. In this case study, the authors demonstrate the potential of using IMU-based motion capture techniques to collect not only acceleration data but also joint and body segment positions, as well as global positions. These measurements, combined with other 3D modeling techniques, provide comprehensive information that can be used to assess amusement rides and devices at every stage of the ride.
