“…Machino [29,30] proposed a 2 DOF robot on wheels, situated on a worksite and controlled by a remote expert. A video camera was fixed to the top of the robot, allowing it to capture the local environment, while a projector was used to project the expert's instructions to the remote worker.…”

A Review on Methods and Systems for Remote Collaboration

Due to the appearance of COVID-19 in 2019, person-to-person interactions were drastically reduced. The impact of these restrictions on the economic environment was significant. For example, technical assistance for commissioning or adjusting the parameters of some complex machines/installations had to be postponed. Economic operators became interested in the possibility of remote collaboration, depending on the manufactured products and the performance of the production lines that they owned. This bibliographic research was undertaken to address these needs. The purpose of this review was to analyze the current solutions, approaches, and technologies that workers and specialists can implement to obtain a reliable remote collaboration system. This survey focuses on techniques, devices, and tools that are being used in different contexts to provide remote guidance. We present communication cues and methods being employed, the implemented technological support, and the areas that benefit from remote collaboration. We hope that our effort will be useful to those who develop such systems and people who want to learn about the existence of collaborative solutions, and that it will increase awareness about the applications and the importance of the domain. We are convinced that, with the development of communication systems, the advancement of remote support systems will be a goal for many economic operators.

“…A system with an additional projector was also developed. Reference [3] had a projector mounted on a mobile robot so that a description was immediately available and could be used at work. Reference [5] installed a projector and a camera on a robotic arm so that a remote expert could control the motor to view images freely.…”

In this paper, we investigate the requirements for fully asymmetric remote collaboration and present a prototype system. Unlike previously studied asymmetric remote collaboration systems, fully asymmetric remote collaboration handles the cases, where a user of one side is a complete novice having difficulty in explaining his/her problems and unfamiliar with a collaboration system, and thus the remote expert of the other side must locate the local user's problem and teach the local user by having full control of the remote collaboration system. These cases can frequently occur when we collaborate with elderly people. For a fully asymmetric remote collaboration system, there are some requirements which are a little bit different from those of an asymmetric one. We itemize them in the three phases of collaboration: identifying a problem, finding a solution, and showing the solution to a local user. We also design and implement a prototype of a fully asymmetric collaboration system to meet the requirements. Our system consists of a robot with cameras and a projector for a local user and an HMD (head mounted display) with a controller for a remote expert. We also design an efficient HMD-based interaction method for fully asymmetric remote collaboration with our system. We show the efficiency of our prototype system in a fully asymmetric remote collaboration situation by user evaluation.

“…The GestureMan (Kuzuoka et al 2004) and SCOPE (Machino et al 2006) systems both allowed the remote expert to inhabit a robot within the physical workspace. The GestureMan system used a laser pointer that the expert could steer by touching a point on a touch screen.…”

A worker performing a physical task may need to ask for advice and guidance from an expert. This can be a problem if the expert is in some distant location. In this paper, we describe a system which allows the expert to see the workplace from the worker's point of view, and to draw annotations directly into that workplace using a pico-projector. Since the system can be worn by the worker, these projected annotations may move with the worker's movements. We describe a method for sticking these annotations to the original positions thereby compensating for the movement of the worker. We call this 'StickyLight'. We conducted a user study to evaluate the performance and user preference for the system in 'sticky' and freehand ('non-sticky') modes. We also compared the system on two platforms: helmet mounted and tripod mounted. Results indicate that freehand conditions took less time than sticky, and that tripod conditions took less time than helmet. However, participants reported preferences for sticky over non-sticky, likely due to the relative discomfort of keeping the helmet steady. This echoes the findings of several recent similar investigations..
