“…The motion simulation system that provided sensory stimulation, iMose, consisted of a 6DOF position-controlled KUKA-based motion simulator system (KR 500-3 MT adapted by BEC GmbH motion simulators, KUKA Roboter GmbH, Germany) and a local area network of three independent workstations [17], [37], [38]. Figures 3B and 33C show the interior and exterior of the simulation system, data was transferred between the simulator and workstations at 250 Hz using UDP.…”

“…Similarly, continuous heading detection perception was investigated using a compensatory task such that behavioral instruction for SD prevention could be improved for aircraft guidance [16]. Most recently, the individual and interactive influences of optical and gravito-inertial stimuli during simulated low-altitude flight demonstrated the importance of sensory integration effects on height perception using joystick response; results were intended to assist with sensorial solution selection for preventing SD [17]. The control theory approach to motion detection was to model typical human response during use-case stimuli and compare error between predicted and actual human response, making it possible to monitor motion detection in real-time [18].…”

A commonly used definition of spatial disorientation (SD) in aviation is "an erroneous sense of one's position and motion relative to the plane of the earth's surface". There exists a wide range of SD use-cases dictated by situational factors, therefore SD has been predominantly studied using reduced motion detection experimental contexts in isolation. The study of SD by use-case makes it difficult to understand general SD occurrence and thus provide viable solutions. To investigate SD in a generalized manner, a two-part Human Activity Recognition (HAR) study was performed. In Part I, a generalized SD perception dataset was created using whole-body experimental motion detection methods in a naturalistic flight context; joystick response was measured during rotational or translational vestibular stimulation. Results showed that SD occurred less for faster speeds than slower speeds, and specific orientations and axes were more difficult to detect motion. Part II evaluated supervised and unsupervised model parameters, including: model architecture, data use-case, feature-type, feature quantity, ground-truth labeling, unsupervised labeling. Long-Short Term Memory (LSTM), Random Forest (RF), and Transformer Encoder models most accurately predicted SD with mean accuracy of 0.84, 0.82, and 0.77 respectively. Using permutation importance (PIM), a dependency score for time, frequency, and time & frequency feature-types quantified the amount that each model architecture depended on a feature-type. The lenient ground-truth label best characterized features, and K-medoids clustering using position and velocity features most accurately replicated ground-truth labels.

Flight simulator sickness (SS) is a well-known phenomenon in aviation training, which can impact the safety and effectiveness of pilot training programs. Identifying and characterizing which flight maneuvers result in increased SS symptoms could help instructors tailor training to increase pilot retention and potentially improve training. The aim of this study was to explore the impact of different flight maneuvers on SS in a fixed-base simulator (ALSIM AL250). Our results indicate that a flight session with more intense flight maneuvers (landing with wind and taxiing) resulted in an increase in sickness symptoms (Total Sickness [ p = .012] and Oculomotor Disturbance [ p = 0.035] of the SSQ) compared to no changes after a session with less intense flight maneuvers (steep turn). These results demonstrate a need to explore which flight maneuvers are more likely to result in increased sickness symptoms and its effects on training and retention of student pilots.
