This video presents the experimental setup of an immersive flight simulation system, which combines body tracking with a head-mounted display. Users are hanging freely in a climbing harness in order to improve the impression to fly. The base system was created by a group of students during one semester as a bachelor project. A study revealed that a high degree of presence is achievable by the combination of body-posture based control and 3D visualization via a head-mounted display while hanging freely in a climbing gear. Furthermore the results of a study that compares two different steering methods are presented. Both control methods seem to be quite interesting and intuitively controllable but show individual preferences among the participants of the study. In our experiments very frequently strong vaction effects were reported when flying turns to one side. The setup very likely causes simulator sickness, especially if a participant was bad in controlling his flight.
