People interpret emojis differently. The idea for the study started when Miller noticed that an emoji she saw on Facebook wasn't the same as what she saw on her phone. I honestly had no clue it was gonna catch fire like this, she said. I honestly had no clue it was gonna catch fire like this, she said. It isn't going to cause a war, she joked. She thinks more study might clear up the emoji communication problem. She investigates how to design technology to improve people's lives. They will study interpretations of emoji from people with different backgrounds and how emojis are used along with language and messages. Miller writes that they found a lot of opportunity for miscommunication. The study involved 304 people chatting in pairs. It can result in significant misunderstandings between people. Still, she admits that emoji miscommunication is not that important. Positive scores were usually happy. Miller's partner, Isaac Johnson, said the students had fun with the study. Understanding its part in how humans communicate could be important in developing new technology, they say.
