Technical details
Tactile feedback allows displaying texture and affordance. In conventional technologies, a single physical quantity is used to render haptic textures. In contrast, Our proposed system physically deforms and changes the physical force between the finger and the device. To achieve this, we combine magnetic and electrostatic fields. We use ferrofluid which is flexible liquid from the magnetic field, and electrovibration with adsorption force from the electrostatic field to develop this device. We investigated the increase in the variation of texture by comparing each single field methods.Movies
