Towards usable underwater virtual reality systems

摘要: The objective of this research is to compare the effectiveness different tracking devices underwater. There have been few works in aquatic virtual reality (VR) — i.e., VR systems that can be used a real underwater environment. Moreover, done noted limitations on accuracy. Our initial test results suggest inertial measurement units work well for orientation but approach needed position tracking. Towards goal, we waterproofed and evaluated several consumer intended gaming determine most effective approaches. First, informally tested infrared fiducial marker based systems, which demonstrated significant optical Next, quantitatively compared (IMU) magnetic system both above water (as baseline) By comparing rotation data, discovered implemented by Razer Hydra more accurate as phone-based IMU. This suggests should further explored applications.
