A development of simple haptic display

Force and tactile feedback greatly enhance the interaction of virtual environment applications. A simple haptics display that has a very high frequency response of the force feedback was developed. The simple haptics display presents force feedback and also vibrotactile information. In the design overview, we propose the categorization of the object presentation data and the data format. We calculated some of these patterns, including tactile and temperature data. The frequency response of the haptics display was examined. The experiments of vibrotactile presentation in contact with wood and aluminum were presented, and a method of the surface roughness presentation were also investigated. Results showed that the simple haptics display provides a sufficient frequency response for presenting vibrotactile information at contact and perceiving a surface roughness of virtual objects
