Interactive holograms of Holocaust survivors debut at Illinois museum

A group of young kids is entranced -- all the more so because Sella is not actually there. Her likeness is being beamed in the form of an interactive and moving hologram, part of a first-of-its-kind exhibition debuting this weekend at the Illinois Holocaust Museum, which aims to preserve accounts of a fast-disappearing generation. "She has their undivided attention," said teacher Samantha O'Neill of Chicago's Northside Catholic Academy. "It really does look like she is sitting on the stage in front of you." The exhibit uses voice-recognition technology and machine learning to let visitors ask questions about survivors' World War II ordeals and hear answers that will grow more relevant as the technology learns.
