Manipulation of visual information does not
change the accuracy of distance estimation during
a blindfolded walking task.

Abstract
While humans rely on vision during navigation, they are also competent
at navigating non-visually. However, non-visual navigation
over large distances is not very accurate and can accumulate error.
Currently, it is unclear whether this accumulation of error is due to
the visual estimate of the distance or to the locomotor production
of the distance. In a series of experiments, using a blindfolded
walking test, we examine whether enhancing the visual estimate
of the distance to a previously seen target, through environmental
enrichment, visual imagery, or repeated exposure would improve
the accuracy of blindfold navigation across different distances.
We also attempt to decrease the visual estimate in order to see if
the opposite effect would occur. Our results would indicate that
manipulation of the static visual distance estimate did not change
the navigation accuracy to any great extent. The only condition
that improved accuracy was repeated exposure to the environment
through practice. These results suggest that error observed during
blindfold navigation may be due to the locomotor production of
the distance, rather than the visual process.
