Communication skills are essential in our everyday lives. Yet, it can be difficult for people with communication disorders to improve these skills without professional help. Quantifying communication and providing feedback advice in an automated manner would significantly improve that process. Therefore, we aim to propose a method to monitor communication that employs life-logging technology to evaluate parameters related to communication skills. In our study, we measured frequency of smiles as a metric for smooth communication. In addition, smiling can improve happiness even if a smile is mimicked. Ultimately, we provided feedback results to users in a gamified form and investigated the effects of feedback on communication.
