Once there, layers of information are added, including animation, videos and fun facts like comparing the whale's weight to 1.6 million slices of pizza. Some are already using the latest 3-D printing technology to make replicas of historical artifacts to give visitors a new way to interact with the object without damaging the original. Museum-goers can peek under the wrappings by manipulating large table-top computer scans placed alongside the delicate specimens to see their clothes, hairstyles and the jewelry they took to their graves. Virtual reality, which utilizes special head gear to create the effects, can transport visitors to places they could never reach, like inside the human body or the bottom of the sea. At a recent special event at the American Museum of Natural History, young visitors tested out virtual reality goggles that "shrank" them to the size of a beetle for a close-up view of the weevil's anatomy. "Telepresence robots" — screens mounted on two long poles on wheels — use videoconferencing technology similar to Skype to connect visitors to expert information not quite available from a tour guide. The American Museum of Natural History tried it out recently at a special event inside its Northwest Coast Indians Hall to beam an indigenous member of the remote Haida Gwaii community into the museum to talk with visitors.
