Behind the Victorian facade of the Dickens World theme park state-of-the-art systems are at work. You might not see them, but without them Dickens World wouldn't have a business. This film explains how the systems work and what they do. TICKETS: It all starts at the front desk with a point of sale terminal. This runs Gamma software specially designed for leisure attractions. More than simply a source of tickets, the system also collects valuable management information. COMPUTER-CONTROLLED: Then when you get inside you find a 4D cinema and real gusts of wind. There's a haunted house complete with ghosts, too - both attractions are controlled by computers. Dickens and other characters make appearances - courtesy of computer-controlled animatronics. SENSORS: But the star attraction is the Great Expectations boat ride where computer-linked sensors make sure the boats are kept far enough part. The theme park's restaurant and shop also depend on computers. A major aim is to collect marketing information - the data it needs to save itself from financial disaster.
