Without human guidance or a preprogrammed map , Grace was to find her way to the registration counter of the American Association for Artificial Intelligence 's 2002 conference , sign in , navigate to the elevators leading to the conference rooms , ' schmooze ' with people in the elevator and hallways , take her place behind the podium , and deliver a lecture about herself . They tested the paper , the ink , the glue that bound the book together , the handwriting , the postage stamps and censorship stamps on postcards and letters that Anne and her family sent during their time in hiding . How did the architecture work along with the propaganda to strike fear and obedience into German peoples ? There were two vice presidents : Emil Puhl , and Kurt Lange , who hailed from the Economy Ministry and was the ministry 's expert in monetery , stock , exchange , and insurance matters .... The solution is recognition of the illogic behind the propaganda , and education about this tragic period of our past . The researchers are also working on similar tools that automate the editing of video clips .
