History in 3-D - San Francisco

Stephen Smith, executive director of the USC Shoah Foundation, demonstrates how a pre-recorded 3-D image of a real Holocaust survivor answers questions in real time on Tuesday in San Francisco. Called New Dimensions in Technology, the USC project also recorded 100 Chinese survivors of the war atrocities committed by Japan's Imperial Army in the early 1930s, in order to preserve the recollections for history.
