A portable fingertip tactile feedback array - transmission system reliability and modelling

In this paper we present our work towards the realization of a portablewearable tactile display in the form of a 4/spl times/4 pin array actuated by miniature remotely (forearm) located motors. The display introduced has a capacity for force generation at up to 3N per tactor and pin displacements of 2.5mm. The bandwidth at this 2.5mm displacement is greater than 15Hz with significantly higher frequency with lower displacements needed in texture simulation. The total weight of the device is approximately 275g of which less than 10g are loading the finger.
