According to similarity attraction paradigm, individuals tend to be attracted to others who have the similar characteristic to themselves. It was supported in many HCI studies that extravert user tend to have more positive interaction with extravert character or interface system component than introvert character or system. However ideal-similarity attraction paradigm emphasize that similarity to person''s ideal self can be more attractive than current self.$$a$$aAccording to CASA paradigm, we may suppose that not only similarity attraction paradigm but also ideal-similarity attraction paradigm can be applied to the human computer interaction.$$a$$aThe aim of the study was to find out the effect of extraversion of human and the character, and both the similarity attraction and ideal-similarity attraction paradigm could be supported.$$a$$aIn the experiment, participants tested their extraversion and ideal extraversion level, then they performed three type of task (calculate, reading and stroop) with extravert or introvert character.$$a$$aThe result of this study showed that the performance of the tasks was not significantly different, but the preference of extravert character was higher than those of introvert character. There was no evidence of similarity-attraction paradigm, however, higher preferences of extravert character could be explained by ideal-similarity attraction paradigm.$$a$$a
