Abstract:
Many modern professional 3D display systems adopt stereo vision and viewer-dependent rendering in order to
offer an immersive experience and to enable complex interaction models. Within these scenarios, the ability
of the user to effectively perform a task depends both on the correct rendering of the scene and on his ability to
perceive it. These factors, in turn, are affected by several error sources, such as accuracy of the user position
estimation or lags between tracking and rendering. With this paper, we introduce a practical and sound method
to quantitatively assess the accuracy of any view-dependent display approach and the effects of the different
error sources. This is obtained by defining a number of metrics that can be used to analyze the results of a set
of experiments specially crafted to tickle different aspects of the system. This fills a clear shortcoming of the
evaluation methods for 3D displays found in literature, that are, for the most part, qualitative.
