  • Patent number: 7777137
    Abstract: The tactile transmission device includes a plurality of cells arranged at regular intervals, each having a storage space therein. A contact member is installed in each of the cells, an upper portion of the contact member protruding out of the cell. An elastic member is installed in each of the cells, and biases the contact member upwards. A sensor is installed in each of the cells, and measures displacement of the contact member. A magneto-rheological fluid is contained in each of the cells. A coil is installed in each of the cells and generates a magnetic field in the cell. A control means compares a shape information value of the image with a displacement value of the contact member output from the sensor, thus controlling a quantity of current applied to the coil. According to the present invention, the shape information of an image displayed on a screen is corrected to be suitable for a user's characteristics, thus more precisely transmitting the shape information on the screen to the user.
