Advanced driving simulators aim at rendering the motion of a vehicle with maximum fidelity, which requires increased mechanical travel, size, and cost of the system. Motion cueing algorithms reduce the motion envelope by taking advantage of limitations in human motion perception, and the most commonly employed method is just to scale down the...

This study assesses the issue of voluntary training of a standardized online competition (serious gaming) between surgical residents. Surgical residents were invited to join a competition on a virtual reality (VR) simulator for laparoscopic motor skills. A final score was calculated based on the task performance of three exercises and was...

The development and tuning of flight simulator motion filters relies on understanding human motion perception and its limitations. Of particular interest to flight simulation is the study of visual-inertial coherence zones. Coherence zones refer to combinations of visual and inertial cues that, although not being physically coherent, still...

The goal of the present study was to explore how simulator motion cuing affects the driver's control performance of a car. Steering behavior was used as a measure of control performance. The experimental task was a slalom maneuver in which the velocity of the car was limited to 70 km/h. Subjective and objective variables were measured. The paper...

The European research project SUPRA (“Simulation of Upset Recovery in Aviation”) produced an extended aerodynamic model for simulation of a generic transport aircraft, capturing the key aircraft behavior beyond aerodynamic stall. As described in the current paper, a group of 11 test pilots with in-flight experience in stall conditions assessed...

This paper describes two simulator experiments studying how accurately pilots can judge and reproduce specific g loads and how their control behavior depends on the sensation of physical g loads during unusual attitude recovery. Seventeen commercial pilots participated. The first experiment shows that pilots tend to overestimate g loads,...

Without visual feedback, humans perceive tilt when experiencing a sustained linear acceleration. This tilt illusion is commonly referred to as the somatogravic illusion. Although the physiological basis of the illusion seems to be well understood, the dynamic behavior is still subject to discussion. In this study, the dynamic behavior of the...

Research on new automotive systems currently relies on car driving simulators, as they are a cheaper, faster, and safer alternative to tests on real tracks. However, there is increasing concern about the motion cues provided in the simulator and their influence on the validity of these studies. Especially for curve driving, providing large...

Generally, motion simulators present motion and visual cues different from each other due to the physical limitations of the motion platform. Nonetheless, high fidelity motion platforms are capable of simulating some maneuvers one-to-one, i.e., motion cues equal to visual cues. However, one-to-one simulation is normally not preferred by subjects...

Desdemona has a fully gimbaled cabin that can, additionally, move vertically plus or minus 1 meter and slide horizontally along an 8 meter track. The track rotates around a central axis, providing a 4 meter long centrifuge arm that can be used to generate sustained accelerations at the cabin. This unique simulator requires specially designed...

The objective of the European research project SUPRA (Simulation of Upset Recovery in Aviation) is to develop technologies that eventually contribute to a reduction of risk of Loss of control - in flight (LOC-I) accidents, today's major cause of fatal accidents in commercial aviation. To this end the project developed novel concepts to improve...

Desdemona is a moving-base research-simulator that was designed with a special focus on spatial disorientation demonstrations, flight simulation, and driving simulation. The cabin is equipped with a car mock-up that contains force-feedback on pedals and steering wheel, and out-the-window visuals. The cabin is mounted in a fully gimbaled system...

The aim of the collaborative European research project ‘Simulation of UPset Recovery in Aviation’ (SUPRA) is to develop breakthrough simulator technologies for teaching pilots to detect and recover from adverse flight upsets that could lead to unusual attitudes and loss-of-control. In the project, the high-performance research simulator...

Knowledge of thresholds for perception of inertial motion is needed for the design of simulator motion filters. Experiments have generally been done to measure these thresholds in isolation, one motion at the time. In vehicle simulation however, several motions occur concurrently. In a flight simulator, both inertial and visual cues are provided...

Pilot perception models include detailed descriptions of the sensory dynamics involved in human spatial orientation. For example, the TNO Spatial Orientation model contains transfer functions of the visual and vestibular system (semicircular canals and otoliths). In our previous attempts to apply this model for the validation of simulator motion...

In co-operation with TNO Human Factors, AMST Systemtechnik developed an advanced simulator motion system based on a 6 Degrees-of-Freedom (DoFs) centrifuge design. The simulator cabin is suspended in a freely rotating gimbal system (3 DoFs, >360°) which, as a whole, can move vertically along a heave axis (1 DoF, ±1m) and horizontally along a...

Following a previous study in the Simona simulator on perception of coherent visual and inertial cues in a flight simulator, an experiment is performed in the Desdemona simulator to investigate the influence of the frequency of visual and inertial stimuli on the limits of the perceived coherence zone. The coherence zone is defined as the range...
