“…Other studies also experimented with various virtual environments for teleoperation for industrial purposes, earthwork being no exception [7]. Diverse interfaces and technologies were tested with positive results, like augmented-reality [8], 2D interfaces [9], digital-twins [10], and advanced environments reconstructions [11].…”

Automation and robotics are destined to play a critical role in the Industry 4.0 revolution, as illustrated by the emergence of autonomous machinery in earthwork operations. Despite rapid progress, autonomous agents will always require human supervision to instruct their mission and to guaranty safety when unexpected problems arise. Traditional human supervision requires an operator to physically enter each machine at risk and manually take control. This approach is time-consuming and requires highly qualified personnel capable of operating various machines. This process can be hastened and simplified by means of teleoperated supervision, which itself requires the appropriate interface. In this paper we evaluate a virtual reality (VR)-based interface using hybrid interactions and an immersive digital-twin compared to a real-life control. We compare these interfaces through control tasks performed by expert and non-expert operators, analyzing time and precision, as well as user feedback. The preliminary results show that the VR interface brings equivalent and satisfactory performances for experts and improves the efficiency of apprentices. Therefore, not only does everyone performs well in the virtual environment, but also the training time can be shortened significantly as non-experts can perform similarly under the same conditions.

“…The major challenge of crane teleoperation opens up opportunities for research on how human-machine interface (HMI) could assist crane operators to perform teleoperation in a productive and safe manner. HMI plays an important role due to its role as the instrument for information exchange between operators and their machines [10]. HMI for teleoperation is supposed to help operators observe the remote environment, make correct decisions, and provide necessary inputs, while trying to minimize cognitive and motoric workload [11].…”

Cranes are traditionally controlled by operators who are present on-site. While this operation mode is still common nowadays, a significant amount of progress has been made to move operators away from their cranes, so that they would not be exposed to hazardous situations that may occur in their workplace. Despite its apparent benefits, remote operation has a major challenge that does not exist in on-site operation, i.e., the amount of information that operators could receive remotely is more limited than what they could receive by being on-site. Since operators and their cranes are located separately, human–machine interface plays an important role in facilitating information exchange between operators and their machines. This article examines various kinds of human–machine interfaces for remote crane operation that have been proposed within the scientific community, discusses their possible benefits, and highlights opportunities for future research.
