Providing the best Third-Person Perspective to a Video-Through HMD

This paper describes a system with several fixed cameras that provide Third-Person Perspective (3PP) to the video-through HMD of the user. Once done, our system uses an algorithm to make intelligent switches between the different cameras in order to provide the best view to the user. User comfort does not suffer from the changes of perspective; some of the users even play at forcing the perspective change during the experiment. Working with an augmented environment larger than a desktop seems to be very promising for future researches in this domain.
