There are some problems in relation to unpleasant feeling or cybersickness due to visual stimulus produced by current digital imaging technology. We specified the time-frequency representation (TFR) of image motion vectors that would affect the autonomic nervous activity under vection-induced images. Referring to the trigger points of cybersickness determined by autonomic nervous activity related indices, we found that the TFR contains both the lower frequency components under 3 Hz with several seconds and the higher frequency components with several hundreds milliseconds. Moreover, the similarity between different image motion vectors, which characterizes the TFR by cos29 between different vectors, changed similarly as the distribution of trigger points of cybersickness in time.
