The FXPAL robotics research group has recently explored technologies for improving the usability of mobile telepresence robots. We evaluated a prototype head-tracked stereoscopic (HTS) teleoperation interface for a remote collaboration task. The results of this study indicate that using a HTS systems reduces task errors and improves the perceived collaboration success and
We also developed a new focus plus context viewing technique for mobile robot teleoperation. This allows us to use wide-angle camera images
that proved rich contextual visual awareness of the robot’s surroundings while at the same time preserving a distortion-free region
in the middle of the camera view.
To this, we added a semi-automatic robot control method that allows operators to navigate the telepresence robot via a pointing and clicking directly on
the camera image feed. This through-the-screen interaction paradigm has the advantage of decoupling operators from the robot control loop, freeing them for
other tasks besides driving the robot.
As a result of this work, we presented two papers at the IEEE International Symposium on Robot and Human Interactive Communication (RO-MAN). We obtained a best paper award for the paper “Look Where You’re Going: Visual Interfaces for Robot Teleoperation” in the Design category.
