Abstract
Abstract A skydiving simulator combines a vertical air chamber with a video projection system on the interior wall. A virtual reality environment is created as the skydiver, while suspended, sees actual film footage of scenarios descending toward earth. A skydiver backpack houses a transmitter which interactively steps the skydiver through emergency procedures.
