Graphics surfaces have a great potential for supporting cooperative work provided they can accommodate a large enough team. However, using large multi-user multi-touch tables leads to a problem of ambiguity as to know who is actually interacting with the table, since gestures are anonymous. This problem is even more severe when one introduces multimodal interaction for example through vocal channels. At UTC we have built a system including a large graphics table and peripheral devices for supporting preliminary cooperative design using multimodal interaction. The paper relates the ambiguity problems that we encountered and how we are trying to solve them.
