Max. Acceleration [°/s2] 460 190 90

The minimum velocity is 0.1°/s on all three axes.

Video projector: mounted on the chair, for showing images on the sphere.

3D coil frame: for measuring horizontal, vertical, an torsional eye position with scleral search coils (binocular).

EyeSeeCam video oculography: for measuring horizontal and vertical eye position (binocular).
