Portable holo-pedestal
From Halopedia, the Halo wiki
The Covenant's Holo-Pedestals are small, cylindrical pedestals that project holograms, similar to Holotanks. They can be used to create holographic maps to find the quickest route to a destination or by AIs to give themselves a holographic "body". AIs can also access the map data from the pedestal's link to the Covenant information network and give directions verbally to anyone near the pedestal. Cortana enters one to gain access to info in High Charity on the level Gravemind, remaining there for the rest of the game. In Halo 3 they are frequently used by the Prophet of Truth to deliver speeches to the Covenant, right up until his death.
Trivia
- In both Halo 2 and Halo 3, the reticule tracks the hologram (though it doesn't turn red) and melee treats it as an enemy.
