Abstract
In tele-operating an UAV human operators fully rely on
cameras to control the vehicle from a distance. To increase operator situation
awareness and reduce workload, a haptic feedback on the control stick has been
developed which acts as an automatic collision avoidance system. A virtual
force field surrounding the moving vehicle interacts with obstacles surrounding
it, yielding repulsive forces on the stick that lead the vehicle away from them.
Albeit successful in significantly reducing the number of collisions, the haptic
interface received low user acceptance ratings. Operators do not always fully
understand the collision avoidance automation intentions, and they experience
the haptic forces as intrusive. This paper discusses the development and
testing of several visualizations of the underlying automation intentions,
primarily the artificial force field. Results of a human-in-the-loop experiment
show that these visualizations indeed led to higher user acceptance ratings, without
affecting the operator’s safety, performance and workload.
