Abstract
In haptic augmented reality, a user can enjoy the sensations of real objects augmented with synthetic haptic stimuli created by a haptic interface. For example, a haptic augmented reality system may allow the user to feel a soft sponge as a stiffer rubber. In this paper, we present a framework in which the stiffness of a real object can be modulated with additional virtual haptic feedback. For this, a commercial haptic interface is extended with a force sensor. Efficient and effective algorithms for contact detection and stiffness modulation are proposed for the closed-loop framework. Performance evaluation with real samples showed that the stiffness modulation is quite capable except for very rigid objects (e.g., a wood plate) where unstable oscillations dominate the response. This work serves as an initial building block towards a general haptic augmented reality system.
