The time constant of the somatogravic illusion

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...

Effect of G-cueing on pilot performance in centrifuge-based simulation of unusual attitude recovery

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...

Ground-based Simulation of Upset Recovery in DESDEMONA: Aspects of Motion Cueing and Motion Perception

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...

Motion perception thresholds in flight simulation

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...

Effect of sway and yaw motion on perception and control; A multi-simulator, follow-up study

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...

Development of the motion perception toolbox

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...
