Haptic augmented reality interface using the real force response of an object

This paper presents the haptic interface system that consists of a base object and a haptic device. The desired force response is achieved by the combination of the real force response of the base object and the virtual force exerted by the haptic device. The proposed haptic augmented reality (AR) system can easily generate the force response of a visco-elastic object with a cheap haptic device and a base object that has the similar visco-elastic property to the target object. In the demonstration, the force response of the target object was generated by using a haptic device only (VR) and using both a haptic device and a base object (AR), respectively. The evaluation experiments by participants show that the AR method has better performance than the VR method. This result indicates the potential of the proposed haptic AR interface.
