Holovision goggles were used to remotely view footage from a holocamera. While the holocam could not be moved, the user could switch between multiple holocams that were set up, expanding their view of an area.
Jacen Solo wore a pair of these goggles while in the Wlesc neighborhood of Pesktda on Garqi. They enabled him, Corran Horn, Ganner Rhysode, and the Resistance to gain intel on the Yuuzhan Vong's Thrall training area there.
