The headset includes a range of amazing hardware designed to create complete reality in a three-dimensional world, and for that to work, you have to plug it into a computer via a 10-foot long USB connection with the display itself connecting via HDMI, and then there's an optional DVI adapter for laptops and/or newer graphics cards for greater compatibility. Oculus has created the headset to have a different screen for each eye, with OLED displays which are very close to the user's face. You'd think this would cause eye strain or tiredness, but the lenses refocus the light as though it were coming from far away, so it takes some of the potential pain away from the fact the display is only inches away. The lenses also magnify the screen to cover more of your vision, which warps the display too.
