Emoji is the picture characters associated with cellular telephone usage in Japan. But now emojis are famous worldwide. The word emoji comes from the Japanese 絵 (e ≅ picture) + 文字 (Moji ≅ written character).
Emojis are icons of faces, weather, vehicles, buildings, food, drink, animals, and plants. These emotions represent feelings or activities. In cellular phone usage, many emoji characters are in a color image. Some are in animated form, usually as a repeating sequence of two to four emoticons, for example, a pulsing red heart.
