Abstract: In an apparatus and a method for displaying a three-dimensional augmented reality, an apparatus to display a three-dimensional augmented reality includes an object area detecting unit to detect a first object area of a left image frame of a three-dimensional image and a second object area of a right image frame of the three-dimensional image based on a selected object of the three-dimensional image; and a frame adjusting unit to adjust the left image frame and the right image frame to change a three-dimensional effect of the selected object.

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.
