| Resumo: | Navigation, in both virtual and real environments, is the process of a deliberated movement
to a specific place that is usually away from the origin point, and that cannot be
perceived from it. Navigation aid techniques (TANs) have as their main objective help
finding a path through a virtual environment to a desired location and, are widely used
because they ease the navigation on these unknown environments. Tools like maps, GPS
(Global Positioning System) or even oral instructions are real world examples of TAN
usage.
Most of the works which propose new TANs for virtual environments aim to analyze
their impact in efficiency gain on navigation tasks from a known place to an unknown
place. However, such papers tend to ignore the effect caused by a TAN usage over the
route knowledge acquisition process, which is important on virtual to real training transfer,
for example.
Based on a user study, it was possible to confirm that TANs with different strategies
affects the performance of search tasks differently and that the efficiency of the help provided
by a TAN is not inversely related to the cognitive load of the technique’s aids. A
technique classification formula was created. This formula utilizes three factors instead
of only efficiency. The experiment’s data were applied to the formula and we obtained a
better refinement of help level provided by TANs. |
