Abstract
This paper is concerned with the perception of complex vibrotactile stimuli in which a few sinusoidal vibrations with different frequencies are superimposed. We begin with an observation that such vibrotactile signals are analogous to musical chords where multiple notes are played simultaneously. A set of “vibrotactile chords” are designed based on the musical chords, and their degrees of consonance (harmony) that participants perceive are evaluated through a perception experiment. Experimental results indicate that the participants can robustly rate the degree of consonance of the vibrotactile chords and establish a well-defined relation of the degree of consonance to the base and chordal frequencies of a vibrotactile chord. These findings have direct implications to the design of complex vibrotactile signals that can be produced by current wideband actuators such as voice-coil, piezoelectric, and electroactive polymer actuators.
