The term identifies a set of digital icons, or pictograms, available on Apple’s mobile operating system. These visual representations are used in electronic communication to express emotions, ideas, or concepts. For instance, a user might employ a smiling face icon to convey happiness in a text message.
The availability of a diverse and updated icon set enhances digital communication by providing users with a wider range of expressive options. A comprehensive selection also allows for clearer and more nuanced exchanges, potentially reducing misunderstandings in online interactions. The continuous evolution of these icon sets reflects the changing needs and cultural trends within digital communication.
