We propose a wearable electrotactile display, which is suitable for augmented reality applications, for a fingertip using a flexible substrate. Since the flexible electrode substrate fits and deforms along with a curvature surface of the fingertip, the user doesn't feel undesirable pressure sensation from the electrode substrate and perceives the shape of a real object when they touch it through the substrate. This indicates that the developed electrotactile display can naturally attach surface textures on a real object. The experimental result indicated that the users correctly recognized the difference in position between an edge of a real object and that of an electrotactile stimulus, i.e., they precisely recognized spatially distributed tactile information from both the real object and the electrotactile display.
