  Since Automated Driving Systems are not expected to operate flawlessly,
Automated Vehicles will require human assistance in certain situations. For
this reason, teleoperation offers the opportunity for a human to be remotely
connected to the vehicle and assist it. The Remote Operator can provide
extensive support by directly controlling the vehicle, eliminating the need for
Automated Driving functions. However, due to the physical disconnection to the
vehicle, monitoring and controlling is challenging compared to driving in the
vehicle. Therefore, this work follows the approach of simplifying the task for
the Remote Operator by separating the path and velocity input. In a study using
a miniature vehicle, different operator-vehicle interactions and input devices
were compared based on collisions, task completion time, usability and
workload. The evaluation revealed significant differences between the three
implemented prototypes using a steering wheel, mouse and keyboard or a
touchscreen. The separate input of path and velocity via mouse and keyboard or
touchscreen is preferred but is slower compared to parallel input via steering
wheel.
