In my experiment, I put two strangers in a room where they were separated by a barrier.
在试验中，我把两个陌生人安排在一个被屏障物分隔开来的房间里。

He sets to work, positioning himself in the corner of the room and taking four steps forward along the barrier wall. He turns ninety degrees, and then steps forward three more paces.
他开始行动，先站在墙的角落处，然后沿着墙向前走了4步，做了个90度转身，又向前走了3步。
