“…In our work with this paper, we have not been able to find extensive literature on this subject, and more specific literature concerned with people experiencing disorientation in the outdoors appears to be lacking. We have found literature concerning spatial disorientation, but it is linked to other research areas like the study of neurodegenerative disorders (for example Monacelli et al, 2003;Tu et al, 2015;Cammisuli and Crowe, 2018;Puthusseryppady et al, 2022), other transport contexts like aviation and pilot training (for example Benson, 1973;Pike, 1992;van Erp et al, 2006;Lewkowicz and Biernacki, 2020;Hao et al, 2022), experiments in simulation or controlled laboratory settings (for example Dariusz, 2018;Lewkowicz and Kowaleczko, 2019;Landman et al, 2022) or within specific activities or even animal navigation (for example Walsh and Martland, 1993;Matthews, 1997).…”

This paper presents the findings from a survey conducted in Norway to study the process of recovering from temporary disorientation in outdoor environments. The survey, with 693 respondents, investigated how individuals navigate and regain their bearings after getting disoriented for a short period of time. By collecting data on duration of disorientation and descriptions of participants' recovery experiences, we conducted both qualitative and quantitative analyses to establish a typology of spatial problem-solving [Downs, R. M. and Stea, D. (1977). Maps in Minds: Reflections on Cognitive Mapping. New York: Harper & Row, p. 55] approaches employed in wayfinding after becoming temporarily lost in outdoor settings. The research systematically explores the use of materials and approaches described by respondents when re-establishing their bearings. The existing research literature lacks comprehensive reporting on people's strategies for solving the problem of being disoriented in the outdoors, which motivated us to conduct this study. The resulting typology gives an overview of approaches employed to solve the problem of being lost in the outdoors and contribute additional details and insights to the understanding of individuals' wayfinding behaviours and reorientation processes.

“…For many years, a special type of fl ight simulator has been used in ground-based fl ight training to demonstrate visual and vestibular in-fl ight illusions and the loss of spatial orientation phenomenon [51]. This type of simulator, e.g., an Integrated Physiological Trainer (IPT) -the Gyro (Environmental Tectonics Corp., US) uses complex motion and visual stimuli which, under certain conditions, may provoke symptoms of simulator sickness.…”

Introduction: A previous study conducted in the Gyro-IPT simulator revealed that applied flight scenarios induced minor severity of simulator sickness symptoms in participants. In this study, however, we did not investigate how the severity of symptoms differs between pilots and non-pilots. Therefore, the presented study aimed to examine whether the symptoms of simulator sickness induced in pilots and non-pilots during spatial disorientation (SD) training are significantly different. We were particularly interested in whether the standard flight scenario used in SD training could be a contributing factor in increasing simulator sickness in novice, inexperienced pilots. Method: We used the data from the previous study, where twenty male military pilots (age 31.6 ±8.22) with flight experience (total flight hours 1300 ±1167.4) and 20 non-pilots (age 30.9 ±7.72) were assigned to one of two groups and then exposed to a 1-hour long flight session (12 flight profiles, six involved an SD-conflict) with active control in the Gyro IPT simulator. To measure simulator sickness symptoms, the Simulator Sickness Questionnaire (SSQ) was administered pre and post-simulator exposure. In the presented study, the SSQ scores were analyzed independently for the total SSQ and subscores for nausea, oculomotor, and disorientation, and then were compared between groups. Results: The score of the total severity and for each subscale of SSQ symptoms in the non-pilots‘ group were higher than those in the pilots group, however, these differences were not significant. Despite the observed differences, according to the SSQ scoring criteria the simulator sickness symptoms reported by the participants after exposure to the applied flight scenario were negligible. Conclusion: The flight scenarios used in SD training did not generate significantly different symptoms of simulator sickness between non-pilots and pilots. The low level of severity of simulator sickness symptoms in these two study groups may indicate difficulty in predicting simulator sickness based on SSQ only.

“…Modern combat aircraft are capable of unconventional flight with unusual orientations. Spatial disorientation (SD) is one of the major threats to the pilots of combat aircraft [8][9][10]. According to the most widely used definition, SD refers to: "a failure to sense correctly the position, motion or attitude of the aircraft or of him/her within the fixed coordinate system provided by the surface of the earth and the gravitational vertical" [11].…”

“…According to the most widely used definition, SD refers to: "a failure to sense correctly the position, motion or attitude of the aircraft or of him/her within the fixed coordinate system provided by the surface of the earth and the gravitational vertical" [11]. Training within SD simulators of different levels of complexity is considered the most effective countermeasure to spatial disorientation [10]. The SDT considered herein is a robot manipulator specifically designed to examine the pilot's ability to recognize unusual flight orientations, to train the pilot to adapt to them and to persuade the pilot to believe in the aircraft instruments for orientation, and not into his senses [7].…”

A development of a robot control system is a highly complex task due to nonlinear dynamic coupling between the robot links. Advanced robot control strategies often entail difficulties in implementation, and prospective benefits of their application need to be analyzed using simulation techniques. Computed torque control (CTC) is a feedforward control method used for tracking of robot’s time-varying trajectories in the presence of varying loads. For the implementation of CTC, the inverse dynamics model of the robot manipulator has to be developed. In this paper, the addition of CTC compensator to the feedback controller is considered for a Spatial disorientation trainer (SDT). This pilot training system is modeled as a 4DoF robot manipulator with revolute joints. For the designed mechanical structure, chosen actuators and considered motion of the SDT, CTC-based control system performance is compared with the traditional speed PI controller using the realistic simulation model. The simulation results, which showed significant improvement in the trajectory tracking for the designed SDT, can be used for the control system design purpose as well as within mechanical design verification.
