Equilibrium organ — enables spatial orientation.
The human equilibrium organ is located in the middle ear. It perceives angular acceleration as well as vertical and horizontal motion. In conjunction with additional information from the eyes and spi-nal cord, this enables conscious orientation in space for our brains.
Users of VR glasses report occasional feelings of vertigo and nausea.
For instance someone wearing VR glasses indeed experiences that acceleration is involved from visual feedback; however the body doesn't report a positional change without a simulator. This contradiction can lead to feelings of vertigo and nausea.
Simulators can resolve perceptual contradiction.
A tipping motion of the body (backwards) simulated forces of acceleration in simulators. The simu-lator constructor must now succeed for instance in ensuring that increased contact pressure against the back, which arises from the tipping motion, is interpreted as acceleration. The VR glasses con-vincingly represent this. The contradiction between the visual and the somatic impression is mini-mized.
Our patented motion device executes this task well.
The hemispherical motion characteristic creates this convincing overall impression. Placing the hu-man pelvis at the centre of the hollow hemisphere locates the former in the region of least position change. On the other hand the equilibrium organ in the middle ear lies in the region of greatest position change. The maximum achievable positional difference value results from this.
This maximum possible offset leads to an efficiency gain and enables creation of the desired per-ceptions in humans even during slight movements. Plausibility among the three sources of spatial-orientation information is thereby increased. The path of motion obtained by the hemispherical mounting can be used for expanded, sensitive characteristics.
