| Research Abstract |
The goal of this research is to formulate the design criteria for developing a successful collaboration support system to be used among different professionals. As a first step to meet this goal, this research investigates how humans communication acts are influenced by the availability of non-verbal communication modalities, and types of information they are able to refer. We conducted three types of experiments in two environments and observed the achievement ratio of the given task and subject utterances. Our experiments have revealed the following : (1) the availability of deictic references (e.g., pointing with a finger) affect the achievement ratio and the content of subject utterances ; (2) the visibility of other subjects does not affect the achievement ratio ; (3) the differences in the environments do not affect the utterance frequencies, their length, or their content ; and (4) average utility of a participant rises significantly only when expected total utility of his/her g
