Abstract: A hologram-based character recognition method in which representative characters are respectively matched to fingers and a group of characters including character objects is matched to representative characters, includes: displaying, when a first movement of a predetermined finger is detected, in a space a hologram image in which a predetermined representative character among the representative characters matched to the predetermined finger is arranged at a center and the character objects included in the group matched to the predetermined representative character are arranged around the predetermined representative character. The method further includes: recognizing the predetermined representative character as an input when a second movement of the predetermined finger is detected; and recognizing one of the one or more character objects as an input when the second movement of the predetermined finger is detected after the predetermined finger is dragged or moved to said one of the one or more character objects.

Abstract: There is provided a multilayer ceramic electronic component. The multilayer ceramic electronic component includes a ceramic main body including a dielectric layer, and first and second internal electrodes disposed to face each other within the ceramic main body and having the dielectric layer interposed therebetween. When an average roughness of center lines of the first and second internal electrodes is Ra, a maximum distance from a virtual line corresponding to Ra to a bottom of a pit (d) formed below the virtual line is 0.1 μm to 13 μm. The surface roughness of the internal electrode printed surface is improved to decrease the occurrence of electrical shorts.
