Statistical validation of utility of head-mounted display projection-based experimental impression evaluation for sequential streetscapes

This study compared the impression structure of streetscapes gained from field experiments with that from head-mounted display virtual reality experiments. The results were as follows: (1) the field experiment experience had a slight influence on the impressions reported from the head-mounted display experiment; (2) few items exhibited significant differences in impression values for the two experiments; (3) the impression structure comprised three factors-"Openness," "Balance," and "Activity"-in both experiments, and (4) no significant difference appeared between the two experiments relative to the subscale scores of these three factors. These results show that head-mounted display experiments can substitute field experiments.
