Induced Pulling Sensation by Synthesis of Frequency Component for Voice-Coil Type Vibrators

Abstract

It is known that humans experience a kinesthetic illusion, such as a pulling sensation in a particular direction, when asymmetric vibrations are presented. In our previous experiment, it was suggested that the fundamental wave and the second harmonic of asymmetric vibration may contribute to this illusion. In this study, we verified whether this illusion can be induced by combining frequency components using three kinds of commercial vibrators through psychophysical experiments. The results confirmed that participants could perceive the correct direction of the pulling force with a correct answer rate of 83.3%.
