  In this paper we present GroupGaze. It is a tool that can be used to
calculate the gaze direction and the gaze position of whole groups. GroupGazer
calculates the gaze direction of every single person in the image and allows to
map these gaze vectors to a projection like a projector. In addition to the
person-specific gaze direction, the person affiliation of each gaze vector is
stored based on the position in the image. Also, it is possible to save the
group attention after a calibration. The software is free to use and requires a
simple webcam as well as an NVIDIA GPU and the operating system Windows or
Linux.
