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 paper investigates how humans communication acts are influenced by the availability of non-verbal communication modalities. We conducted two 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; and (3) the differences in the environments do not affect the utterance frequencies, their length, or their content.
