The holoviewer or holoviewer screen was a type of hologram technology that linked up to the holo-sensors of probe droids. During the mission to colonize the moon, Ohma-D'un, Obi-Wan and Amidala used the holoviewer screen in the Mantaris-class amphibious medium transport. This particular holoviewer received images from both halves of ER-1C, one half monitored the plants and animals and the other half monitored the new Gungan colony.
