The representation of texture is a major concern during fabrication and manufacture in many industries. Although it is easy to change the texture of objects in the digital world (i.e. just setting texture parameters), it is difficult to achieve this in the real world. Tactile feedback allows displaying texture and affordance. In conventional research, 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.
