Product personality in physical interaction

The possibility of designing physical human–product interactions with predefined personalities was explored in two studies. In the first study, 60 participants reported the personality of two devices that were developed to be identical in terms of appearance and different in terms of interaction style, i.e. dominant versus elegant. In the second study, 75 respondents reported the personality of the same devices but this time with a dominant instead of a neutral appearance. The results indicated that it was possible to design interaction devices with different personalities, and that the effect of appearance is stronger than that of interaction style.
