Exploring alternative security warning dialog for attracting user attention: evaluation of "Kawaii" effect and its additional stimulus combination

One of security functions is a security warning dialog (SWdialog). However, the effect for ensuring security is questionable because of the habituation. This means that users tend to disregard of it through repeated encounters. In this paper, we propose an alternative security warning dialog using the effect of "Kawaii", which means "cute" in Japanese. We also propose a combination of additional effects with "Kawaii" to the dialog. We conducted an evaluation experiment with a small number of subjects in order to verify whether the proposed dialog has a potential of expected affection to users. From the results of the experiment, we find that the proposed dialog could obtain user attention better than the conventional dialogs. Moreover, one of proposed dialog that is applied the effect combined additional effects with "Kawaii" would have a potential to suppress disregarding action to the dialog even if a user is habituated.
