Shape and weight rendering for haptic Augmented Reality

Haptic interfaces in Augmented Reality scenarios are an efficient way to enhance the interaction with a virtual world. We introduce a new system that involves both hands in virtual object experience. We render contemporary shape and weight of a virtual object, merged in a real world environment, using a commercial haptic interface and a new kind of finger-worn device. We test the system with an experimental setup where a virtual cube is placed over a real marker. The system developed can be used in several applications of augmented reality where rendering only the object shape is not enough to perceive the virtual world. It can also lead towards the introduction of more wearable devices in the haptics augmented reality context.
