From VOA Learning English, this is the Technology Report. Scientists in Switzerland are developing virtual reality technologies to recreate crimes scenes. The scientists say this kind of technology helps police, investigators, judges and lawyers better visualize, or picture, crime scenes. The scientists work at the Institute of Forensic Medicine in Zurich. They developed a special computer software called Forensic Holodeck to create this virtual reality technology. It recreates crime scenes using hand-held three-dimensional, 3-D, scanners. The scientists also use the Oculus Rift headset, equipment used for video games. Investigators use 3-D images to rebuild the crime. The images are based on reports from witnesses and camera recordings. Steffen Ross is a radiologist at the Institute of Forensic Medicine. Mr. Ross explains if there is a dead body involved, they scan it. Then that image is combined with other data and put in a computer, which creates a 3D model. The software can rebuild the bullets’ paths. Red and yellow lines are used to show their movement through the air. The institute also developed a robot named Virtobot. Medical examiners can use Virtobot to perform virtual examinations of bodies in great detail. Robert Breitbeck is a scientist with the Institute of Forensic Medicine. He says the system provides a 3-D model of the human body. Scientists can make colored images of things like injured skin true to the exact sizes. This information is combined with 3-D data. Mr. Breitbeck says the scientists can then reconstruct or recreate images from murder cases or traffic accidents.
