In this study, we developed a portable driving system for Diminished Haptics that transforms the haptic textures of real materials by ultrasonic vibration based on a squeeze film effect. A real material is attached on the display area (a square area with 30-mm sides), and its haptic texture is reduced. However, the vibration amplitude is decreased due to a shift of resonance frequency when user’s finger contacts with the haptic display. Thus, a resonance frequency tracing system in the driving system plays an important role in maintaining the vibration amplitude. In this paper, we focus on the details of the resonance frequency tracing system and the effect of the system is evaluated.
