ESTIMATE OF DISTANCE COVERED IN THE TREKKING WITHOUT VISION
The objective of this paper was to investigate the course estimate using the trekking with controlled hearing and smell indications. For that, an experiment was applied that sought to investigate the course estimate with 10 participants with vision, that accomplished Trekking in a trail of 800 meters. Those people walked blindfolded, and they were instructed to locate the landmarks and to tell the walked course estimate in meters. All of the verbal information was logged and analyzed reaching the conclusion that the estimate of distance covered without vision doesn't possess a satisfactory accuracy due to estimate variability among the subjects and accentuated course underestimate.
