Understanding emotion for self-awareness requires recognizing not only its type and intensity but also the surrounding context and the insights it provides. While prior work has studied emotion recording, little attention has given to how such records might foster reflection on context. To address this gap, we developed Moodialogue, a system that enables users to personify emotion and engage in dialogue with it. In a six-week field study with nine participants, we found that personified emotion records supported dialogues that uncovered overlooked contexts and coexisting feelings beyond a single entry. Participants also reported savoring positive emotions more deeply and reframing negative ones from new perspectives. These findings point to design opportunities for systems that move beyond recording, enabling post-recording interactions that deepen reflection on emotional context and meaning.

Nowadays, many mobile instant messenger (MIM) users employ stickers to express their emotions. Due to the increase in the variety of stickers, many MIM platforms have begun to offer sticker recommendation services, which suggest appropriate stickers based on the context of conversations. Although sticker recommendation services need to consider users' subtle social and psychological needs from the perspective that stickers are an alternative communication language, few attempts have been made to explore this area. Consequently, we investigated sticker usage practices through a qualitative study with 18 KakaoTalk users in South Korea. Based on the results of this study, we revealed user's three common considerations in sticker usage experiences and discussed the design implications for sticker recommendation services in MIM.
