The mean point of vergence is biased under projection

Wang, Xi ; Holmqvist, Kenneth ; Alexa, Marc (2019-09-09)

The point of interest in three-dimensional space in eye tracking is often computed based on intersecting the lines of sight with geometry, or finding the point closest to the two lines of sight. We first start by theoretical analysis with synthetic simulations. We show that the mean point of vergence is generally biased for centrally symmetric errors and that the bias depends on the horizontal ...
