Do We Really Need This?
Yeah, what was up with that? Was she supposed to be like, from the future or something? And if so, why didn't she just tell us the results?
No, it was just Jessica Yellin, a CNN correspondent. CNN beamed her image from Chicago to the CNN press center in New York City, where Wolf Blitzer and the rest of the team were covering election returns.
Yellin, who claimed she was the first person to be beamed in a "hologram" on live TV, explained for the audience how this was done. (See video below.) She said she was standing in a tent outside of the Obama headquarters in Chicago where the CNN crew had set up 35 high-definition cameras in a ring. She stood in the center of this ring and the cameras picked up her every movement and transmitted the image in 3D to the studio in New York.
While CNN is touting its special effects from election night as a '"hologram," that may not be technically the case. CNN's "hologram" seems to have been done using overlay images and a green screen to virtually put the reporter in the same studio as Wolf Blitzer. But true holography uses a different technique to create a true 3D image of a person standing in the studio. According to Wikipedia, "holography is a technique that allows the light scattered from an object to be recorded and later reconstructed so that it appears as if the object is in the same position relative to the recording medium as it was when recorded. The image changes as the position and orientation of the viewing system changes in exactly the same way as if the object was still present, thus making the recorded image or hologram appear three-dimensional."
