It happened in a New York classroom. Sixteen-year-old Taylor Engler came face to face with a cow. But it was all in her head.
She was trying out a virtual reality (VR，虚拟现实) headset (头戴式眼罩). It took Berkeley Carroll School junior students to a farm 400 kilometers away.
Students across the US are taking VR “trips”. They are swimming in the deep sea. They are watching medical operations (手术). They are even “walking” through the human body. Teachers say this helps students understand their learning materials.
“It attracts (吸引) the students right away,” Colin Jones, a science teacher from Plainview-Old Bethpage Central School District, told AP News. He uses a VR system called zSpace to cut up cells (细胞).“It's something that can be done in 40 minutes,” he said.“But it could take even a week when you're doing this in a lab.”
“It's different than watching videos because you can have more than one perspective (视角). You can actually move,” Taylor said during her “trip” on the farm.
According to the expert Richard Lamb, VR can give people experiences that are similar to the real world. Our bodies even react the same to VR as they do to real-life situations.“Heart rate, brain activity, breathing, everything,” he said.
But there are not many classrooms that can use this technology. VR systems are very expensive. Experts hope that more students can use it in the future, especially for doing dangerous science experiments.
