VR Parasailing Simulation

Mar 2017 - Oct 2017

In this project, we present a flotation simulation in a cable-driven virtual environment. For this, a virtual parasailing system was developed, where the visual stimulus was provided through a VR headset and the physical stimulus was given by wires. In order to prevent the user from moving out of the limited workspace of the cable-driven system, the visual acceleration was washout-filtered to produce the physical acceleration. In the parasailing trajectory, we focused on the stages of vertical acceleration/deceleration and conducted an experiment to identify how much gain can be applied to the visual acceleration, which makes the user feel the natural self-motion when integrated with physical stimulus. Then, the results were tested using several types of full-course virtual parasailing. The results showed that fairly large differences between visual and physical stimuli would be accepted and different gains could be assigned depending on the user's altitudes.
This research was funded by the National Research Foundation of Koera (NRF).
