Comparison of interactive communication with and without a specified theme during co-creative drawing

Real-time communication helps makes more creative activities for co-creative. However, the COVID-19 pandemic has made face-to-face communication difficult. For this situation, there is a need to enable distant users to execute co-creative actions and communication in real time. When producing artwork together, users should be able to immediately communicate how they are thinking and behaving with each other. On the other hand, in improvisational work production, adaptive decision-making based on the situation at any time is also indispensable. In a distant co-creation environment, information channels to know each other’s status are limited, making it difficult to determine how this communication should be carried out. This paper addresses this issue by conducting experiments under two conditions, with and without themes, and observing the differences in user behavior for each situation.
