Abstract: In a transmission apparatus, a reception apparatus and a method for performing communication using chrominance information, a transmission apparatus includes a symbol converter to obtain a symbol from data; a symbol modulator to generate a chrominance value based on the symbol; a luminance controller to generate a luminance value; a color space converter to generate an RGB value based on the luminance value and the coordinate value; and a light emitting unit to emit light based on the RGB value. A reception apparatus includes a visible light receiver to receive light and to generate an electrical signal having RGB color information of the light; a color space converter to generate a luminance value and a chrominance value based on the RGB color information; a symbol demodulator to obtain a symbol based on the chrominance value; and a data converter to convert the symbol to data.

Abstract: In an apparatus and a method for performing communication by using polarization property of light, a transmission apparatus includes a controller to establish a first channel corresponding to a first polarization property; a signal encoder to encode data into an electrical signal; a light emitting unit to emit light based on the electrical signal; and a polarizer to polarize the light into first polarized light having the first polarization property, and to output the first polarized light. A reception apparatus includes a controller to establish a first channel corresponding to a first polarization property; an analyzer to receive light, and to extract first polarized light having the first polarization property from the light; a polarized light receiver to convert the first polarized light to an electrical signal; and a signal decoder to decode the electrical signal to digital data.

Abstract: An interface apparatus and method that may display an interface image by synthesizing a reference resonance frequency with the interface image, and may transmit a resonance occurrence frequency to the displayed interface image to generate a resonance between the reference resonance frequency and the resonance occurrence frequency to provide a user with sensory feedback.
