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...

Desdemona is an advanced motion simulator that was developed in a co-operation between TNO Human Factors and AMST Systemtechnik (Ranshofen, Austria). The main purposes of Desdemona are to facilitate research into motion cueing, simulator training and effectiveness, and the design and evaluation of innovative motion platforms. The simulator will...

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...

Rationale: Due to costs and penalties the ratio between ground based training and flying hours will soon drastically change. Evidence based arguments are needed to support proper decisions on what to train where.

The three Dutch research institutes NLR, TNO and TU Delft are collaborating to perform a multi-simulator follow-up study aimed at investigating the influence of yaw and translational motion cues in helicopter- and general flight-simulation. In this study, new experimental results will be combined with pilot modeling. Two experiments will be...

The goal of this paper is to give an overview and some practical examples of the Motion Perception Toolbox developed by TNO (Netherlands Organization for Applied Research) as a freeware Matlab Simulink library. The MPT library provides a documented set of building blocks that model human perception and are easily coupled to existing simulation...

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...

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 very unique and novel motion platform DESDEMONA was taken into start-up operation early this year. This next generation motion platform allows 6-DoF movement combined with the capability of producing sustained g-forces. These features make the simulator extremely valuable for future flight simulation applications as well as for...

In the spring of 2007 TNO Human Factors together with AMST Systemtechnik GmbH have completed the development of their newest research simulator, the Desdemona, in The Netherlands. The Desdemona research simulator features a unique motion system not seen elsewhere in the world. Its serial design and geometrical dimensions give the motion system a...

Unsuccessful recovery from unusual flight attitudes, or “airplane upset”, is considered an important factor in civil aviation accidents. It is generally recognized that there is a clear need for enhanced training of recovery procedures from unusual flight attitudes, i.e. situations where an aircraft unintentionally exceeds the parameters of the...

In centrifuge simulators pilots experience the G-forces and fast G-onsets encountered in the real fighter aircraft. The motion cueing principle that drives these simulators is based on creating G-forces by increasing the centripetal force of the centrifuge through a rotation of the simulator arm. The centrifuge usually spins at a constant 1.4 G...

In the real world in which we move around, inertial and visual motion are usually equal; what you see is what you feel. In a simulator, however, this is usually not the case. On the contrary, due to the relatively small motion space of even the largest simulators, the inertial motion cues must be filtered and scaled down considerably. Typically,...

The importance of motion perception knowledge for flight simulation is widely recognized. The development and tuning of motion filters relies on understanding the human motion perception mechanisms and its limitations. Particularly interesting for flight simulation is the study of visual-vestibular coherence zones. Coherence zones refer to...

During advanced driving manoeuvres, drivers can be hypothesized to use all the available cues to optimize their performance. Fixed-base simulators are commonly used for training of these advanced driving manoeuvres, despite the fact that motion cues are not present. In this experiment we hypothesize that motion feedback improves driver...

The goal of this study was to assess the effect of an increasing motion space on the fidelity of driving simulation in the Desdemona research simulator. The experimental task was a standardized slalom maneuver where the car velocity was limited to 70 km/h. Subjective measures, which included eight statements on realism and task performance were...
