Virtual reality recreates a Roman's eye view In AD 79，the ancient Roman city of Pompeii，in southern Italy，was destroyed by a volcanic eruption （火山爆发） that buried many of its buildings.Archaeologists （experts who study man-made objects to understand history）have been observing it for almost 300 years but now they have a new tool for understanding how Pompeii might once have looked-virtual reality （VR） .
   Researchers Danilo Campanaro and Giacomo Landeschi，from Lund University in Sweden，used data collected by drones （无人飞机） flying over the ruined Roman city to create a 3 D computer reconstruction （重建） of one of its most impressive buildings.They then fed the reconstruction into a video game system called Unity （which is used by the smartphone game Pokemon Go） to make a VR model.The idea is not just to recreate the buildings but also to understand a bit more about how Roman people might have experienced them.
   Campanaro and Landeschi asked volunteers to take a virtual tour of the house in both summer and winter light.The researchers used special eye-tracking technology to record exactly which areas people looked at and for how long.From this，the team concluded that the building used clever design to draw attention to objects that showed off the wealth and status（地位） of its owner-perhaps a man called Lucius Valerius Flaccus，whose ring was found in the ruins.
