Unimodal or bimodal distributions across non-visible pointing trials. Target locations are indicated by red dots and numbered by gray circles. Circular histograms indicating pointing directions are shown at corresponding testing locations. A green or dark gray sector plots the 95% confidence interval of the average pointing direction for each modal. For bimodal distributions, errors that were modeled as the higher angular deviations from the correct pointing directions were assumed as systematic errors and indicated by the dark gray sectors
