Laser mirror galvanometer: used to project a visual target on either a space fixed screen, or on a chair mounted screen, in order to provide targets for fixation, smooth pursuit, or saccades.

Dual video projectors: mounted in front of the hexpod, and back-projected onto a screen in front of the hexpod. Stereo images are possible with anaglyph glasses.

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).
