Co-creative sessions involve design teams, clients and end users. During these sessions, a large variety of design representations are used. This paper focuses on the current practice of co-creative sessions by analyzing discussion and interactions between designers and clients. For this purpose, we recorded a meeting where we analyze the speech and different types of gestures occurring between participants using multiple artefacts (tangible, digital and virtual). Finally, an analysis combining both methods was carried out. The results confirm that artefacts played a significant role in the co-creative process and when those artefacts are missing participants simulate their need through gestures in thin air called imaginary artefact. The results also show that more than one artefact can be involved at the same interaction, this what we call Multiple marker. It also spots the fact that more than one interaction can happen at the same time, called aside marker which allow us to distinguish the principal interaction from the secondary ones.
