 Our hypothesis is that timely switching between different LOAs will enable the system to overcome various performance degrading factors and thus enable superior performance compared to systems in which LOAs cannot switch on-the-fly. Statistically validated analyses from the two experiments provide evidence that: a) Human-Initiative (HI) systems outperform purely teleoperated or autonomous systems in navigation tasks;
