This user-centered design project invites students to conduct hands-on human-computer interaction research and design by exploring affect-aware technology. These technologies seek to account for users’ emotions, moods, and other affective phenomena in the user experience. Examples include emojis used while texting, social robots that model emotional responses, and emotionally-aware chatbots. This project is for a user-centered design and usability testing course offered to undergraduate computer science students. The course learning objectives are to use research and design methods to (1) build an empirical understanding of technology stakeholders and (2) apply that knowledge to design and evaluate an interactive prototype. By immersing themselves in the complex domain of affect-aware computing, students learn to apply user-centered design to emerging technologies. Students create and refine common user-centered design artifacts, including personas, interaction designs, and prototypes. The reader of this paper will obtain recommendations for structuring the user-centered design project and a high-level understanding of affect-aware computing.
