An apparatus for displaying information indicating interaction between a group of users, the apparatus comprising: a fixed microphone array configured to: generate respective outputs corresponding to each actively speaking user of the group of users; and means configured to: receive, from a plurality of steerable microphone arrays, respective spatially filtered outputs corresponding to a respective look direction of each respective user, each steerable microphone array arranged to be worn by a respective user of the group of users a processor configured to: determine a plurality of look directions corresponding to a plurality of users of the group of users based on a comparison between respective spatially filtered outputs of the plurality of steerable microphone arrays and respective outputs of the fixed microphone array, determine, based on the plurality of look directions, that one or more users of the group of users are looking at a particular user of the group of users, the particular user wearing a particular steerable microphone array of the plurality of steerable microphone arrays, and generate a user interface that displays an output based on the plurality of look directions, wherein the user interface is configured for collaboratively zooming into a representation of the particular user. a fixed microphone array configured to: generate respective outputs corresponding to each actively speaking user of the group of users;
