Basic performances. a and b Accuracy assessment using a model eye rotating at a speed of 8.18°/s in the absence or presence of translations made by moving the model eye by ~1 mm in random directions once every three screen oscillations. a Sample time-courses of the estimated pupil azimuth. b The relation of the actual to estimated pupil azimuth. The mean lines are flanked by the ±SD lines (n = 5 for each condition)
