In this paper, the first air-flow based multifunctional tactile display with 1-D mixed array of integrated air nozzles and multi-jet integrated micro venturi atomizers are presented. This device realizes simultaneous tactile presentation of “object surface shape” by distributed air-flow pressures and “sense of cold (cryesthesia)” by arrayed liquid mist injection. A new type venturi atomizer with multi jet structure was developed to control the mixture ratio of different liquids for temperature control. 2-D tactile display can be realized by simply stacking the 1-D array devices. Through the evaluations with fabricated devices, multifunctional and distributed tactile presentation has been successfully demonstrated for the first time.
