We propose the concept of an opinion model for interactive multimodal services and apply it to an audiovisual communication service. First, psychological factors of an audiovisual communication service were extracted by using the semantic differential (SD) technique and factor analysis. Forty Subjects participated ill Subjective tests and performed point-to-point conversational tasks on a PC-based video phone that exhibited various network qualities. The subjects assessed those qualities On the basis of 25 pairs of adjectives. Two psychological factors, i.e., all aesthetic feeling and a feeling of activity, were extracted from the results. Then, quality impairment factors affecting these two psychological factors were analyzed. We found that the aesthelic feeling was affected by 113 packet loss and video coding bit rate, and the feeling of activity depended oil delay time, video packet loss, video coding bit rate. and video frame rate. Using this result, We formulated all opinion model derived from the relationships among quality impairment factors, psychological factors, and overall quality The validation test results indicated that the estimation error of our model wits almost equivalent to the statistical reliability of the subjective score.
