Figure 1: We model the relationship between a primary gaze direction and a social charge via a social saliency field inspired by Coulomb's law. The two social charges (the blue and green points) generate the social saliency saliency field on the left figure. The size of the social charges is proportional to social saliency. In the right figure, we show the probability distribution over gaze direction modeled by a mixture of von-Mises Fisher distributions.
Figure 2: We estimate a social saliency field that reflects the selective gaze behavior. An arrow represents the predicted primary gaze direction at the location.
We present a method to predict primary gaze behavior in a social scene. Inspired by the study of electric fields, we posit ``social charges" - latent quantities that drive the primary gaze behavior of members of a social group. These charges induce a gradient field that defines the relationship between the social charges and the primary gaze direction of members in the scene. This field model is used to predict primary gaze behavior at any location or time in the scene. We present an algorithm to estimate the time-varying behavior of these charges from the primary gaze behavior of measured observers in the scene. We validate the model by evaluating its predictive precision via cross-validation in a variety of social scenes.
