We evaluate two methods of signalling abrupt direction changes of a robotic platform using a Mixed Reality avatar. The "Body" method uses gaze, gesture and torso direction to point to upcoming waypoints. The "Path" method visualises the change in direction using an angled path on the ground. We compared these two methods using a controlled user study. Results indicate that each method might excel in different situations. The "path" technique was more accurate in communicating the direction change of the robot but participants overall preferred the "Body" technique.
