 Despite the larger model research on kinesthetic haptic device design and haptic effect modeling, there is limited work assessing the impact of parameter variation of these haptic effects on perceived realism of kinesthetic haptic devices. In this work, we investigated the effect of parameter variation on perceived realism for a common set of haptic effects. The results suggest that changes to perceived realism are dependent on haptic property that is varied and can provide insight for haptic device design and for required accuracy of model parameters.
