The Influence of the feedback control of the hexapod platform of the SAAM dynamic driving simulator on neuromuscular dynamics of the drivers
2012
Multi sensorial cues (visual, auditory, haptic, inertial, vestibular, neuromuscular) [Ang2] play important roles to represent a proper sensation (objectively) and so a perception (subjectively as cognition) in driving simulators. Driving simulator aims at giving the sensation of driving as in a real case. For a similar situation, the driver has to react in the same way as in reality in terms of ‘self motion’. To enable this behavior, the driving simulator must enhance the virtual immersion of the subject in the driving situation. The subject has to perceive the motion of his own body in the virtual scene of the virtual car as he will have in a real car. For that reason, restituting the iner…
MOTION SICKNESS IN CHILDHOOD MIGRAINE
2017
Background: Migraine is a chronic, progressive, and debilitating disorder that has an impact on the lives of millions of individuals. The origins of the disability can be traced into childhood and adolescence for most adult migraine sufferers. The group of periodic syndromes consists in symptoms related to migraine, thought to be migraine equivalent or precursors. Aim of this study is to assess the role of MS as risk factors for childhood migraine. Materials and methods: 441 subjects (211 Females) aged 6-13 years (mean 9.20; SD 2.42), consecutively referred between October 2007 to March 2009 for primary headaches to pediatric Centers for Headache in Childhood. Control group consisted of 365…
Visually Induced Motion Sickness on the Horizon
2020
Visually induced motion sickness is an unpleasant but common side-effect of many simulations and VR-applications. We investigated whether an earth-fixed reference frame provided in the simulation is able to reduce motion sickness. To do so, we created a moving starfield that did not contain any indicators of the spatial orientation of the observer. As the observer was simulated to move through the randomly oscillating starfield, a time-to-contact task had to be carried out. Two colored stars on collision course with each other had to be spotted, then they disappeared and the time of their collision had to be judged. Eye-movements, task performance, and motion sickness were recorded. This co…

Clinical verification of a unilateral otolith test.
1992
Abstract In a previous study13 we reported promising results for a new test to differentiate in vivo unilateral otolith functions. That study pointed to a need for further validation on known pathological cases. In this presentation we will detail the results gathered on a group of clinically verified vestibular defectives (verum) and a normal (control) group. The subjects in the verum group were former patients of the ENT clinic of the university hospital. These subjects had usually suffered from neurinoma of the VIIth cranial nerve or inner ear infections. All had required surgical intervention including removal of the vestibular system. The patients were contacted usually two or more yea…
