Towards post multimedia interactions, we envision real world oriented interactions with Computational Generated Fields on Air; we called this interaction concept as “Computational Ether”. Along this concept we have conducted studies to propose a method for realizing new physical interactions that expands malleability of non‐digital material towards programmable matter in the real world [1]. Our method utilizes light field [2] and acoustic field [3] these are calculated, generated, and controlled by computers. By applying such computational fields of quantities and physical phenomena around the holographic field, we transformed ordinary air into interactive visual media [2], haptic media [4], and actuators [3]. To implement these interactive media, we employed Computer Generated Hologram and rendered with ultrasound generated by acoustic phased array and laser induced plasma generated by femtosecond laser sources with Spatial Light Modulators. In this paper, we introduce the results of our research group such as case studies; aerial haptic interaction, aerial touch displays, 3D manipulation of objects, new material expression displays, and so on. Finally, we discuss the advantages and limitations of our method. We believe these technologies stimulate display researches from 2D pixels on the surface towards 3D pixies flying in the air.
