Weird Butterfly Ceremony

課文：

Technology companies are working around the clock. Their goal: to use computers to create a 3-D environment that people can interact with. Virtual reality is working to let people go deeper and deeper into a world that exists only inside a computer.

around the clock：日以繼夜（ = 24/7）
interact：互動
inter-：互相
virtual reality：虛擬實境
exist：存在、生活

The display

For users to be fully immersed in this virtual world, watching it on a screen is not enough. The virtual world must be all they see.

To make that happen, companies are developing virtual-reality headsets with two screens, one in front of each eye. The screens display slightly different pictures, which makes objects appear in 3-D.

immerse：沈浸在、埋首於
im-：進入
slightly：稍微地、輕微地

The input

Companies have developed several systems to let users influence the different virtual worlds they create. Some controllers resemble the ones used for video games. Others called data gloves detect hand motions, letting people interact naturally with the virtual environment.

One company, Motion Analysis, developed a suit with markers that let off light, allowing nearby cameras to track the wearer’s motions. The cameras create a computer model of the person, which copies the user’s motions in the virtual world.
