4 Data processing and analyses

Different data were collected during the study. During the interaction, the commands and the windows used by the subjects were indexed temporarily and filed automatically. The actions of the subjects, the modalities used, the duration and the contents of the commands were supplemented a posteriori starting from video film of the interaction. Lastly, the recording of the autoconfrontations was carried out in order to allow qualitative analyses starting from the identification of intentions and the strategies of the subjects as for the use of the modalities.
