Emoji is the picture characters associated with cellular telephone usage in Japan. But now popular worldwide. The word emoji comes from the Japanese 絵 (e ≅ picture) + 文字 (Moji ≅ written character). Emoji 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 colour image. Some are in animated form, usually as a repeating sequence of two to four images, for example a pulsing red heart.
