Abstract
This paper presents the third phase of an analytical research on product aesthetic sustainability that its outline has been introduced in the first paper of these serial articles generally entitled 'An Inverse Approach to Product Aesthetic Durability'. The focus of research is on product aesthetic boredom, the opposite of product aesthetic durability. The individuals' actual experience of product aesthetic boredom has been surveyed during the second phase of research. But this third phase of research aims at experimenting with the subjects' appraisal of boredom of the objects in relation to the objects' form-structural characters. The choice of samples of two groups of mobile phone used in Japan and Iran and the form-structural variables are based on the results of the second phase of research presented in the last paper. Finally, it compares the derived form-structural patterns and their rates of boredom appraised by the Japanese and Iranian subjects regarding the same samples.
