VR is no longer only for gaming or enjoyment. An American company called Blue Goji is using VR to improve one's health by making exercise more fun. Blue Goji has offices in Austin, the capital of Texas.The company showed its workout machine called the Infinity treadmill (跑步机) at the South by Southwest festival. A person using the treadmill wears a virtual reality headset when exercising. Before starting, the user is connected to a belt to prevent falls. Then, the user plays a VR game while running on the machine. The game can transport the user into the virtual world, where he or she can be racing against virtual people. The cost of the hardware and the computer software program is $12，000. That means much for most people. But Kyra Constam of Blue Goji says the virtual reality treadmill is ideal for places where people go to exercise, like highend gyms or recreation centers. Recently, Leonardo Mattiazzi tested the Infinity treadmill. Mattiazzi said he had a strong feeling to actually get running and do something that pushed his limits. He said the experience was more interesting than running inside the gym without actually going anywhere. Constam noted that a lot of VR experiences cause motion sickness (晕动病) because people are in motion during the game, but not moving in real life. But when the user is moving on the treadmill and in the game, the chances of motion sickness are reduced. She said there is generally a learning curve for VR.The first time users feel lost, but the more you do it, the more you get used to it. After carefully studying the users' experiences, Blue Goji plans to begin selling the Infinity treadmill to the public. 阅读自测 1．What are users most likely to do after running on the Infinity treadmill _____ A.Make more new friends.
