We live among and belong to various social communities. Relationships and bonds with these communities are formed by daily communications. There are two main communication channels: verbal and non-verbal. Non-verbal communication channels are important for creating relationships within communities. Facial expressions are formed implicitly, and it is difficult for a person to know his/her expressions when having a conversation. Thus, we present a case study in which participants explore their own facial expressions by taking photos while having conversations. The process of the exploration includes taking photos, categorizing and labeling each expression, and making a pictorial book using these photos. Through this process, participants were able to know his/her expressions explicitly, which allowed them to reflect on their interactions within conversations. This indicates that, the process encourages meta-cognitive explorations by participants. Therefore, the participants gain new insight on their daily communications.
