       abstract = {Visual Focus of Attention (VFOA) estimation in conversation is challenging as it relies on difficult to estimate information (gaze) combined with scene features like target positions and other contextual information (speaking status) allowing to disambiguate situations. Previous VFOA models fusing all these features are usually trained for a specific setup and using a fixed number of interacting people, and should be retrained to be applied to another one, which limits their usability. To address these limitations, we propose a novel deep learning method that encodes all input features as a fixed number of 2D maps, which makes the input more naturally processed by a convolutional neural network, provides scene normalization, and allows to consider an arbitrary number of targets. Experiments performed on two publicly available datasets demonstrate that the proposed method can be trained in a cross-dataset fashion without loss in VFOA accuracy compared to intra-dataset training.},
