Abstract
In this paper, we propose to evaluate the benefits of event-based haptic rendering in virtual environments subject to high damping or low contact stiffness. In such context, the degraded perception of contact impairs the manipulation performance and the overall user's experience. Haptic rendering techniques known as event-based (or open-loop) rendering have been proposed to improve the realism of contacts in such contexts.We conducted a preliminary experiment to investigate the effect in terms of performance of haptic event-based technique on virtual environments using different parameters of damping and stiffness. The first results suggest that event-based haptic can improve the perception of contact for such environments (particularly with high damping and/or low stiffness).
