Input: Instant messaging is one of the major channels of computer mediated communication. However, humans are known to be very limited in understanding others’ emotions via textbased communication. Aiming on introducing emotion sensing technologies to instant messaging, we developed EmotionPush, a system that automatically detects the emotions of the messages end-users received on Facebook Messenger and provides colored cues on their smartphones accordingly. We conducted a deployment study with 20 participants during a time span of two weeks. In this paper, we revealed five challenges, along with examples, that we observed in our study based on both user’s feedback and chat logs, including (i) the continuum of emotions, (ii) multi-user conversations, (iii) different dynamics between different users, (iv) misclassification of emotions, and (v) unconventional content. We believe this discussion will benefit the future exploration of affective computing for instant messaging, and also shed light on research of conversational emotion sensing.
