The relationship between the way of locomotion and visual search in maze - comparison between fixations of active-locomotion in way-finding and passive-locomotion in wheelchair

摘要

To clarify the differences between fixations of active-locomotion and passive-locomotion, two experiments were conducted in a small maze. The subjects wearing an eye camera tried to find the goal in active way-finding experiment, whereas, in the passive-locomotion experiment, subjects rode on a wheelchair pushed by an experimenter. Through the four trials of active way-finding, the entire path was learned and fixation movements were more continuous than before. However; for passive-locomotion, some subjects learned the path well and their fixation movements were more continuous, but some did not learn the path well and their fixation movements were more scattered. In active way-finding, fixation moved ahead before the head and body; however, this was not characteristic for the passive-locomotion. In passive-locomotion, sometimes fixation moved ahead right after the body and head rotated, and sometimes fixation moved to the opposite direction while the body and head rotated.
