Catching jellies in immersive virtual reality: A comparative teleoperation study of ROVs in underwater capture tasks

Abstract

Remotely Operated Vehicles (ROVs) are essential to human-operated underwater expeditions in the deep sea. However, piloting an ROV to safely interact with live ecosystems is an expensive and cognitively demanding task, requiring extensive maneuvering and situational awareness. Immersive Virtual Reality (VR) Head-Mounted Displays (HMDs) could address some of these challenges. This paper investigates how VR HMDs influence operator performance through a novel telepresence system for piloting ROVs in real-time. We present an empirical user study [N=12] that examines common midwater creature capture tasks, comparing Stereoscopic-VR, Monoscopic-VR, and Desktop teleoperation conditions. Our findings indicate that Stereoscopic-VR can outperform Monoscopic-VR and Desktop ROV capture tasks, effectively doubling the efficacy of operators. We also found significant differences in presence, task load, usability, intrinsic motivation, and cybersickness. Our research points to new opportunities towards VR with ROVs.
