Guideline effects on the movement accuracy in virtual torus spaces with various guidelines are investigated by means of moving deviations from an indicated path. Guidelines with various widths are set at the center or the sides (upper, lower, left and right) in virtual torus spaces. Participants travel at a constant velocity in full-sized virtual torus spaces for various guideline conditions. It is shown that there exists a tendency that moving deviations from the indicated path are more reduced as the guideline width becomes narrower and the movement accuracy is improved. For example, in the case of side guidelines with the width of 10 cm or less, the mean value of moving deviations is approximately reduced to half of that with no guidelines. By setting side guidelines, the value of the standard deviation of moving deviations is approximately reduced to 2/3 of that with no guidelines.
