Intelligent switch: An algorithm to provide the best
third-person perspective in augmented reality

Abstract
Augmented reality (AR) environments are suffering from a
limited workspace. In addition, registration issues are
also increased by the use of a mobile camera on the user
that provides a first-person perspective (1PP). Using
several fixed cameras reduces the registration issues
and, depending on their location, the workspace could
also be enlarged. In this case of an extended workspace,
it has been shown that third-person perspective (3PP) is
sometimes preferred by the user. Based on the previous
hypotheses, we developed a system working with several
fixed cameras that can provide 3PP to a user wearing a
video see-through HMD. Our system uses an ``intelligent
switch'' to propose our ``best view'' to the user, i.e.
avoiding markers occlusion and taking into account user
displacements. We present in this paper, such a system,
its decision algorithm, and the discussion of obtained
results that seem to be very promising within the AR
domain.
