Designing effective haptic interaction: inverted damping

In this paper, we describe a new force-feedback technique termed "inverted damping", which aids users in manually selecting specific items from within a range of possible choices. Typically, the identity of the goal item is not known beforehand by the system. The technique therefore infers users' intentions from the type of movements carried out and increases the amount of resistance provided as the speed of the user's movements decreases. Although the technique might initially sound counter-intuitive, the results of the experiment, reported in this paper, confirm the effectiveness of this approach. We believe that this new technique is likely to have beneficial and wide-ranging applicability across a wide range of devices in everyday life. Keywords Haptic Interaction, Force Feedback, Damping
