A touch based affective user interface for smartphone

Nowadays, people interact with smartphones constantly throughout their daily lives so that smartphones become the most ideal device for recognizing users´ physiological and emotional states. In this paper, we present a novel approach for providing users with personalized interface by inferring human emotions based on the touch behavior of a smartphone. Recognizing human emotions is a challenging task and we propose to use touch related data to infer user´s emotional states. We also propose a personalized user interface which applies the observed emotional variance to emotion-aware interaction between users and the devices.
