Robotic proxy brings remote users to life in real time

Robotic proxy brings remote users to life in real time
Two collaborators are reviewing a physical artifact remotely by using the ReMotion system while sharing information on a digital whiteboard. We show both sites (Left and Center). At each site, the system includes (Center): a Kinect Azure to capture body motions, a NeckFace system worn by the local user to capture head and facial expressions, the embodiment robot, and ArUco markers board used by the robot for position feedback. The ReMotion robotic proxy (Right) uses an omnidirectional platform for movement fexibility and an articulated display to render head orientation and facial expressions.

Cornell University researchers have developed a robot, called ReMotion, that occupies physical space on a remote user's behalf, automatically mirroring the user's movements in real time and conveying key body language that is lost in standard virtual environments.

"Pointing gestures, the perception of another's gaze, intuitively knowing where someone's attention is—in remote settings, we lose these nonverbal, implicit cues that are very important for carrying out design activities," said Mose Sakashita, a doctoral student of information science.

Sakashita is the lead author of "ReMotion: Supporting Remote Collaboration in Open Space with Automatic Robotic Embodiment," which he presented at the Association for Computing Machinery CHI Conference on Human Factors in Computing Systems in Hamburg, Germany. "With ReMotion, we show that we can enable rapid, dynamic interactions through the help of a mobile, automated robot."

The lean, nearly six-foot-tall device is outfitted with a monitor for a head, omnidirectional wheels for feet and game-engine software for brains. It automatically mirrors the remote user's movements—thanks to another Cornell-made device, NeckFace, which the remote user wears to track head and . The motion data is then sent remotely to the ReMotion robot in real-time.

Telepresence robots are not new, but remote users generally need to steer them manually, distracting from the task at hand, researchers said. Other options such as and mixed reality collaboration can also require an active role from the user and headsets may limit peripheral awareness, researchers added.

In a small study, nearly all participants reported having a better connection with their remote teammates when using ReMotion compared to an existing telerobotic system. Participants also reported significantly higher shared attention among remote collaborators.

In its current form, ReMotion only works with two users in a one-on-one remote environment, and each user must occupy physical spaces of identical size and layout. In future work, ReMotion developers intend to explore asymmetrical scenarios, like a single remote team member collaborating virtually via ReMotion with multiple teammates in a larger room.

With further development, Sakashita says ReMotion could be deployed in virtual collaborative environments as well as in classrooms and other educational settings.

The paper is also published as part of the Proceedings of the 2023 CHI Conference on Human Factors in Computing Systems.
