| Resumo: | The correct distance perception is important for executing various interactive tasks
such as navigation, selection and manipulation. It is known, however, that, in general,
there is a significant distance perception compression in virtual environments, mainly
when using Head-Mounted Displays - HMDs. This perceived distance compression may
bring various problems to the applications and even affect in a negative way the utility
of those applications that depends on the correct judgment of distances. The scientific
community, so far, have not been able to determine the causes of the distance perception
compression in virtual environments. For this reason, it was the objective of this work
to investigate, through experiments with users, the influence of both the field-of-view -
FoV - and the distance estimation methods on this perceived compression. For that, an
experimental comparison between the my3D device and a HMD, using 32 participants,
seeking to find information on the causes of the compressed perception, was executed.
The results showed that the my3D has inferior capabilities when compared to the HMD,
resulting in worst estimations, on average, in both the tested estimation methods. The
causes of that are believed to be the incorrect stimulus of the peripheral vision of the user,
the smaller FoV and the smaller immersion sense, as described by the participants of the
experiment. |
