Abstract: The present invention relates to a tactile transmission method and system in which when a user applies an action force to a tactile feedback apparatus on a transmission-side, a reaction force which reflects attributes of the action force and is proportional to the attributes is generated from a tactile feedback apparatus on a reception side so as to be transferred to a reception-side user. As described above, according to the tactile transmission method and system using tactile feedback apparatuses of the present invention, when a transmission-side user applies an action force to a tactile feedback apparatus on a transmission-side, a reaction force which reflects attributes of the action force and is proportional to the attributes is wirelessly transferred to a reception-side user located at a remote place, thereby enabling exchange of various contact information.

Abstract: A method of and an apparatus for reproducing texture, in which a garment product designed by a designer is reproduced using a computer. A visual texture of the product is reproduced by applying the reproduced product to a virtual model, and displaying the virtual model, on which the product is put, on a screen. A tactile texture of the product is also reproduced by driving a tactile texture reproducer based on the surface characteristics, softness and heat transfer coefficient of a fabric to be applied to the product. Based on the reproduced visual and tactile textures, consumers experience the virtual texture of the product through their virtual and tactile senses. Accordingly, it is possible to positively reflect opinions of consumers on products being developed. This makes it possible to develop products having a better chance of market success while reducing the labor, time and costs required in the developments of products.
