Emojis differ across different devices. What you send from your iPhone will look different on a Microsoft or Samsung phone. But a group found that sending certain emojis can send different messages.
A study by the Grouplens Research team at the University of Minnesota asked subjects to rate 22 emojis from five different platforms using a scale that ranges from strongly negative (-5) to strongly positive (5).
Some emojis like the "loudly crying face" and the "sleeping face" had mixed reactions, the "grinning face with smiling eyes" was the most polarizing among research subjects.
One of the researchers, Hannah Miller said in a blog post, "We're excited about continuing this work along a number of fronts: considering emoji in the context of full text messages, investigating emoji communication breakdowns for people from different national cultures, asking similar questions of non-anthropomorphic emoji, building systems to help test the potential for miscommunication in a new emoji rendering, and so on. More generally, a number of scholars have argued that emoji represent a fundamental shift in language use. As such, fully understanding emoji's role in human communication will be an important step in developing the next generation of language technologies."
