What Are You Talking About While Driving?: An Analysis of In-car Conversations Aimed at Conversation Sharing

In this study, we propose an in-car conversation sharing system. People frequently converse in a car. In these conversations, people often talk about points of interest that they have just passed. Because we believe that they contain useful information, the aim of our study is to share the conversations. To develop such a system, we needed to know about the characteristics of in-car conversations. Consequently we collected 120 in-car conversations with their locations over a 10-month period. Our analysis showed that many types of conversation take place in a car; but of the greatest interest is when the subject of conversation is a specific location or area. We discuss the requirements for an in-car conversation sharing system to guide our on-going research.
