In this paper, we will present an evaluation experiment of Stream Public Opinion Channel (SPOC) from contents creators perspective. This system allows a contents creator to publish programs using not only multimedia but also conversational information in sync with interface agent and multimedia. Contents creator of SPOC needs to make a story with consideration of agent ç-' actions and their effect on audience. Therefore, it is important to evaluate the effect of interface agents on contents creators. Results of the experiment showed that contents creators positively accepted the SPOC in subjective evaluation, but they could not successfully embody what they want to express as a story. Additionally, we found correlations between the impressions of interface agent and factors which would form users behavioural intention. We need to measure not only subjective evaluation but also objective indicator in evaluation.
