On a typical day at East Shore Middle School in Milford, the library is where students spend time using the computers, working on projects and checking out books. But on a recent Monday morning, about a dozen students sat at tables, each with a virtual reality headset strapped onto their faces and a controller in one hand. Instead of seeing each other, Tino Pavlat and his friends interacted with people at a virtual high school and played Space Cats, a shooter minigame.
