About pointing, in Table 8 is presented the number of times the group pointed a piece of
furniture or to the table during each stage, the third row correspond to the Reviewing
periods during the Implementation stage. Groups 2 and 3, same with the better performance
in both collaborative process and the scores about the task, used the pointing mechanism
during the Planning and the Reviewing stages, but Group 2, the highest score, pointed
during Implementations most of the time during Reviewing periods.

Table 8. Pointing to the furniture and the workspace.
Gazes were now observed under a different perspective. It was detected that the change of
view mechanism was being used, although as mentioned not while the user was talking or
speaking, the users usually change their viewpoint repeatedly before doing something else,
an average of 4.02 movements.
Because in real life people change the direction of gaze in a regular fashion notably
associated with utterances (Kendon, 1990), it was decide to observe what the users were
doing after they changed their viewpoint. For that, only the groups that went through the
four stages were included. Results are shown in Table 9 for Groups 1 and 2 of the first
trial; Table 10 for Groups 3 and 4 of the first trial; and Table 11 for Groups 2 and 3 of the
second trial.
