Controlling the Perceived Vibrational Frequency and Amplitude of a Voice-Coil-Type Tactor

When designing a vibrotactile information display, it is important to present correct, stable stimulation. However, the mechanical stability of the vibration is affected by many conditions such as how the vibrators are attached to the person, where they are attached, and other factors. In order to maintain the target frequency and amplitude of the vibration independent of the affective factors, we propose a feedback method for vibrotactile displays.
