Query: LinkRing: A Wearable Haptic Display for Delivering Multi-contact and
  Multi-modal Stimuli at the Finger Pads   LinkRing is a novel wearable tactile display for providing multi-contact and
multi-modal stimuli at the finger. The system of two five-bar linkage
mechanisms is designed to operate with two independent contact points, which
combined can provide such stimulation as shear force and twist stimuli,
slippage, and pressure. The proposed display has a lightweight and easy to wear
structure. Two experiments were carried out in order to determine the
sensitivity of the finger surface, the first one aimed to determine the
location of the contact points, and the other for discrimination the slippage
with varying rates. The results of the experiments showed a high level of
pattern recognition.
