This paper presents a method to simultaneously compute optimal simulator motions and simulator parameters for a predefined set of vehicle motions. The optimization can be performed with a model of human motion perception or sensory dynamics taken into account. The simulator dynamics, sensory dynamics, and optimality criterion are provided by the...

Recent work from several groups has shown that perception of various visual attributes in human observers at a given moment is biased toward what was recently seen. This positive serial dependency is a kind of temporal averaging that exploits short-term correlations in visual scenes to reduce noise and stabilize perception. To date, this...

BACKGROUND: Linear acceleration generally gives rise to translation perception. Centripetal acceleration during centrifugation, however, has never been reported giving rise to a radial, inward translation perception. OBJECTIVE: To study whether centrifugation can induce a radial translation perception in the absence of visual cues. METHODS: To...

In the field of motion-based simulation, it was found that a visual amplitude equal to the inertial amplitude does not always provide the best perceived match between visual and inertial motion. This result is thought to be caused by the "quality" of the motion cues delivered by the simulator motion and visual systems. This paper studies how...

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...

Humans are able to estimate the vertical direction of an Earth fixed reference frame, which estimate is known as the subjective vertical (SV). To identify the SV, a distinction must be made between accelerations due to self-motion and gravity. Previous studies on this topic measured the SV using a variety of methods possibly affecting the...

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...

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...

Tactile displays provide information by applying local vibrations to the user's skin. The research organization TNO has developed a tactile torso display by implementing a number of pager motors, or “tactors” into a vest, allowing for the generation of spatio-temporal patterns. TNO carries out research into the usefulness of this tactile torso...

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...

We used a desktop computer game environment to study the effect Field-of-View (FOV) on cybersickness. In particular, we examined the effect of differences between the internal FOV (iFOV, the FOV which the graphics generator is using to render its images) and the external FOV (eFOV, the FOV of the presented images as seen from the physical...

A set of experiments were conducted on the National Aerospace Laboratory (NLR) GRACE research flight simulation facility to determine the effects of sway, yaw and roll motion on perceived motion fidelity, motion perception, pilot workload and pilot compensation. Fourteen pilots were asked to perform a manual decrab maneuver when the aircraft was...

In this flight simulator study, eleven pilots rated their motion perception during a series of decrab maneuvers of a twin-engine passenger aircraft. Simulator yaw, sway, and roll motion were varied independently to examine their relative contribution to the pilots’ judgments. In one set of conditions, the washout algorithms were bypassed so as...

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...

The visual perception of human movement from sparse point-light walkers is often believed to rely on local motion analysis. We investigated the role of local motion in the perception of human walking, viewed from the side, in different tasks. The motion signal was manipulated by varying point lifetime. We found the task of coherence...

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...

This paper shows that tactile stimulation can override vestibular information regarding spinning sensations and eye movements. However, we conclude that the current data do not support the hypothesis that tactile stimulation controls eye movements directly. To this end, twenty-four subjects were passively disoriented by an abrupt stop after an...

We examined to what extent body tilt may augment the perception of visually simulated linear self acceleration. Fourteen subjects judged visual motion profiles of fore-aft motion at four different frequencies between 0.04-0.33 Hz, and at three different acceleration amplitudes (0.44, 0.88 and 1.76 m/s2). Simultaneously, subjects were tilted...
