Abstract: While many wearable tactile displays for the fingers, such as fingertip-type and glove-type displays, have been developed, their weight and size typically hinder the free movement of fingers, especially when considering the multi-finger scenario. We propose a method of presenting the haptics sensation of the fingertip on the forearm, not on the fingertip, to address this issue. A five-bar linkage mechanism was adopted to present a two-degree-of-freedom force. We presented a pressure sensation and a horizontal friction sensation perceived by the index finger and thumb to forearm, and the realism of the grasping experience in virtual reality was better when using the designed device than for no haptics cue or for vibration conditions.
