Ego +Ego −Allo +Allo −

Participant 1“I can use it like a white cane”“I’m following the next waypoint but I feel lost”“Ok, I found the waypoint back”“I need to follow the ship for a long time to perceive the heading”
“I have no idea of the trajectory I did on the map”

Participant 2“It’s intuitive: ahead is in front of me”“I need to concentrate a lot to remember the initial layout”“here, I remember the map”“It was hard to identify the heading.”
