Emotional responses towards the use of rectilinear, symmetrical curvilinear and asymmetrical curvilinear forms in virtual environments

The aim of the study is to understand the effect of various forms in designs of interior environments and compare different emotional responses of people towards those environments. Therefore, this study was conducted to compare positive or negative emotional responses of people experiencing interior environments designed by three different forms: rectilinear, symmetrical curvilinear and asymmetrical curvilinear. Twelve virtual interior settings were created according to these forms. A questionnaire involving Mehrabian and Russell’s PAD adjective pairs was utilized to measure emotional responses of 61 volunteer respondents contacted on Balgat Campus of Çankaya University. The results of one way ANOVA tests illustrated that respondents felt more pleasant and aroused in the setting designed with asymmetrical curvilinear forms than other settings. Moreover, men tended to be more aroused in the setting designed with symmetrical curvilinear forms than women.
