Bos, J.E. Publication year 2012 Abstract 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 outcome differently. In this study subjects were sinusoidally moved around their naso-occipital axis and their SV was dynamically measured using a joystick. In half the experimental conditions, the joystick was moved with the motion and was kept vertical on other experimental conditions, thus moving against self-motion. Although physically indicating the same angle, the average perceived angle was larger when moving the joystick with the motion than against. The difference can be explained by assuming an idiotropic vector being at issue when measuring the subjective vertical, and not when measuring subjective tilt.We hebben gevonden dat de subjectieve verticaal wat anders is dan een kantelsensatie waarvan het dynamische gedrag beter gemeten kan worden met ene joystick dan met een nieuwe ontwikkelde audio-methode Subject HumanPCS - Perceptual and Cognitive SystemsBSS - Behavioural and Societal SciencesSpaceAviationInformation SocietyMotion perceptionSpatial orientationSubjective verticalSubjective tiltJoystickPhase measurement To reference this document use: http://resolver.tudelft.nl/uuid:bb2719b3-61eb-4b1e-9b6c-77f8883c8b6f DOI https://doi.org/10.3233/ves-2012-0454 TNO identifier 465793 Source Journal of Vestibular Research, 22 (4), 181-189 Document type article Files To receive the publication files, please send an e-mail request to TNO Library.
