12. The whiteboard is the central space for sharing information (in this task)

13. Whiteboard Display Persistent Non-Persistent Knowledge Persistent Non Persistent MOO dialogues

14. Grounding varies according to problem solving variables

15. Acknowlegment in MOO dialogues • Rate = 41% (90% in voice experiments) • Not related with MOO expertise • Not related with interactions parameters • symmetry(ack+): 8% = symmetry(ack-): 8% • ack (short delay): 41% = ack (long delay): 41%; • ack (freq+.talkers): 41% = ack (freq-.talkers): 42%; • turnsIC (ack+): 0.9 = turnsIC (ack+): 0.9 • Related with problem sloving • N. actions (ack+):178 <<.05 N. actions (ack-) : 237 • redudancy (ack+): 6 <<.01 redudancy (ack-): 18
