Abstract
The objective of the study is to evaluate whether use of apparent motion can be an effective presentation method for velocity information. Ten subjects participated in the experiment where they perceived apparent motion generated by air-jet and they controlled the speed of the moving object on the PC screen to express their perceived velocity. As a result, perceived velocity decreased significantly as the ISOI was increased. Perceived velocity changed with the duration when the ISOI was between 30---70 ms and when apparent motion was provided. Duration only affected perceived velocity when apparent motion is provided to the subjects. In conclusion, apparent motion generated by stimuli can be effectively used to transmit precise velocity information tactually.
