A hand-held controller with haptic feedback for virtual reality

Hand-held input devices with vibrotactile feedback for virtual reality systems have been widely used in order to transfer user's intention to virtual environment. However, it is very challenging to originate the vibration and to propagate it to the desired direction. Therefore, we fabricate a new vibrotactile actuator with piezo material and create vibration flow using the fabricated vibrotactile actuator. We also construct a simple application program as a test bed to applied vibration flow with the piezo actuator.
