"The arrangements of Joint Attention with interactive interfaces" by Dimitri Voilmy
The thesis is based on excerpts of video recordings in teaching situations with children or training situations with adults. Two research questions are at the heart of my analysis: how are the participants sensitive to the fact that they are involved in the same activity? How are mutual intelligibility and common understanding of the current activity accomplished?
The study of the achievement of joint attention in spatial co-presence with visualization interfaces appears to be a complex social formation, which brings out the procedural rules and moral responsibilities. Several human phenomena emerge from my analysis: the phenomenon of two social orders that are intrinsically linked during the organization of turns at the IWB, the prosodic marking on the first name when selecting the next participant depending on the situation of spatial co-presence and eye contact, and the achievement of the collaborative instruction.
