In a desktop video conferencing system, a plurality of user stations 2-14 are interconnected to exchange data. Each user station 2-14 stores data defining three-dimensional computer models of the participants in the conference, and displays images of the models to a user. Each user station uses a pair of cameras 26, 28 to record images of the user wearing coloured body markers 70, 72 and a headset 30 on which lights 56-64 are mounted. The image data is processed to determine the movements of the user and the point in the displayed images at which the user is looking. This information is transmitted to the other user stations where it is used to animate the corresponding computer model. Each computer model is animated so that movements of its head correspond to scaled movements of the user's head. Image data is processed in each user station to determine the type of transformation which relates the positions of the camera 26, 28 to be used in determining the user's movements. The sound of the other participants is output to the headset 30 worn by a user. The sound is adjusted in dependence upon the position of the user's head. |
