Cover Story: For realistic finger-based object manipulation in augmented reality (AR), haptic rendering of object stiffness is important yet challenging due to the co-presence of real hands, haptic devices, and rendered AR objects. Thus, we propose a novel wearable haptic device, which can generate rigid and elastic haptic feedback in a small form-factor with a simple mechanism to minimize occlusions in the AR scene. Through human-subject experiments in AR, the efficacy of our proposed haptic device is verified/compared against other feedbacks (vibrotactile, visual) for stiffness rendering. View this paper
