| dc.description.abstract | This paper aims to provide a framework to model human belief and misperception in helicopter overland navigation. Helicopter overland navigation is known to be a challenging cognitive task, and understanding the cognitive processes associated with it is non-trivial. Two sets of human-inthe- loop experiments were conducted to investigate pilot misperception during simulated overland navigation by analyzing actual navigation trajectory, pilots’ alleged location, and corresponding confidence levels. No significant correlation between perceived and actual location of the aircraft was found, indicating that confidence is not a good indicator of performance. There is however some evidence that there is a negative correlation between perceived location and intended route of flight, suggesting that there is a perception bias towards the intended flight route. Observed visual misperception can be summarized into: 1) confusion between inference and evidence, 2) incorrect mutually exclusive assumptions on the data, and 3) biased sampling. Simulation results on two cases observed in the experiments are given. Quantitative differences in dynamic perceptions between a Bayesian agent and misperceiving humans are presented with the suggested modeling framework. | en_US |
