Visualising Collision Spot Uncertainty with Augmented Reality

When trying to avoid collision in a scene with other persons, one makes an initial guess of a location where the conflict might happen before choosing paths. Then the estimated conflict spot serves as a deciding factor in choosing a safe trajectory to avoid the intruder. However, the predicted collision point is subject to one’s estimate of the other person’s future movement. The prediction is linked to guess made with a degree of uncertainty. In this paper, we summarize on how we use AR visualizations to symbolize different levels of uncertainty of predicted collision spots to study path choice influences
