There are 100 emojis depicting human faces, many of which can be used to depict varying levels of happiness. The levels of happiness range from the standard smiley face, which is displayed with a closed-mouthed smile, to the elated face, which includes an open-mouthed smile.
The emoji keyboard also includes faces from various cultures and ethnicities that a user can also select to express happiness, as most of these culturally specific faces are smiling. There are also a number of hand gestures that can also express happiness, including the high-five, the thumbs-up, the waving hand or the praying hands.
The emoji keyboard also includes a series of animal images. The smiling monkey, the frog face or the cartoonish whale, for example, can each be used to express happiness. Among the nature emojis are a smiling sun and moon and flowers, which can also be used to depict varying levels of happiness. Depending on the context, an emoji user can also select more abstract happiness images, such as the rainbow, confetti, fireworks or different colored hearts to convey happy emotions. Of course, the understanding of happiness will change depending on the person using the emoji, but most of the emoji options generally express happiness.
