These emoticons are usually found in a format similar to (*_*). The asterisks indicate the eyes; the central character, commonly an underscore, the mouth; and the parentheses, the outline of the face. Two separate studies, in 2007 at Hokkaido University and in 2009 at Glasgow University, showed that Japanese and other East Asians read facial expressions by looking mainly at the eyes, and the researchers noted that this is reflected in East Asian emoticons which put emphasis on the eyes, compared to Western emoticons which emote mainly with the mouth.
