Thi s research i s to anal yze the spati al i nformati on search features whi ch shown by Eye fi xati on and movement and conducted eye tracki ng experi ment for targeti ng sports shop spati al i mages whi ch i t are same but l ooks di fferent. Thi s i s abl e to fi nd out the eye movement feature accordi ng to pl acement of goods from the eye movement and movement di stance of spati al vi si tor, and the resul t can be defi ned as fol l owi ng. Fi rst, the whol e ori gi nal -reverse l eft / ri
... -reverse l eft / ri ght i mages have a hi gher number of observati ons i n the [IN] area than i n the [OUT] area. Thi s i s because after eye taki ng hi gh observati ons i n LA area of [IN] have been j ump-over [OUT], performed search acti vi ti es i n l ow eye fi xati on wi thout hi gh eye fi xati on. Second, there was a di fference i n the frequency of the observati on data as the composi ti on of the i mages changed. The ori gi nal i mage has been often fi xed the eyes i n LA area, and the one that has been observed for a l ong ti me i s reverse l eft / ri ght i mage. Al so, fi xati on poi nt was shown hi gher at the reverse l eft / ri ght i mage as j ump-over from [OUT] area to [IN] area. If LA area seen as reverse l eft / ri ght i mage, i t i s l ocated i n ri ght-hand si de. The case where the domi nant area i s on the ri ght si de has a characteri sti c that the eye fi xati on i s l onger. Thi s can be understand that the arrangement of products for attract the customer's attenti on i n the commerci al space mi ght be more effecti ve when i t i s on the ri ght si de. Thi rd, the movi ng di stance(IN → OUT) of the si ght poi nted to external from LA area was l ong i n the both ori gi nal -reverse l eft / ri ght i mages, but i t i s no rel ati on wi th search di recti on([IN→OUT]․[IN→OUT]) of the si ght. In other words, the si ght that entered i n LA area can be seen as vi sual percepti on acti vi ty for re-searchi ng after bi g j ump-over, i n the case go i n to outward (OUT area) after searchi ng for more than certai n ti me. The fact that the movi ng di stance of eye i s rel ati vel y short i n the [IN → OUT] process consi dered as that the gaze that stays outsi de the LA area natural l y enters i n to LA area.
