摘要：An SD (semantic differential) method is an effective way to evaluate subjective impression of an AV (audio visual) content. However, because the SD method is performed after viewers watch an AV content, it is difficult to examine their impression of detailed scenes in the AV content in real time. To measure viewer's impression of an AV content in real time, we have developed a “Taikan sensor” that precisely measures the viewer's grip strength and body temperature. Based the Taikan sensor measurement, we investigated the relationships between the viewers' impression and their grip strength. Factor analysis of the viewers' impression was performed on detailed scenes when the grip strength became strong. Results showed that the viewers' impression influenced their grip strength and the viewer received an “active” impression from the AV content when the grip strength increased. Therefore, the Taikan sensor enables real time measurement of a viewer's “active” impression from an AV content.
