From Cave Paintings to Emoji: How Visual Symbols Shaped Modern Digital Communication

Emoji, also known as emoticons or picture‑based expressions, have become an indispensable part of everyday social communication, allowing users to convey emotions more precisely than plain text.

Visual Origins

The use of images to transmit messages dates back to prehistoric times when early humans painted simple symbols on cave walls to record events or actions, a practice that later gave way to written language.

From Printed Symbols to Digital Icons

On March 30, 1881, four printed “vertical emoticons” appeared in the American satirical magazine Puck , marking the earliest known use of visual symbols for emotional expression.

In 1982, Professor Scott Elliott Fahlman at Carnegie Mellon introduced the first electronic emoticon “:-)” on a message board, paving the way for modern digital emojis.

Japanese Kaomoji

Japanese users created “kaomoji” (顔文字) such as ^_^ or ╰(*°▽°*)╯, using combinations of characters to depict facial expressions.

Emoji Standardization

In 1999, Shigetaka Kurita of Japan designed the first standardized 12 × 12 pixel emoji set for pagers, which later became part of the Unicode standard and spread across mobile phones and social platforms.

Compared with kaomoji, emoji offer richer detail within a compact size, and many platforms now provide their own emoji sets, typically featuring only a head for simplicity.

Academic Recognition

In August 2014, the Oxford Dictionary Online added “emoji” as an official entry, and the 2015 Emoji Report showed that 92 % of internet users employ emojis, with the “Face with Tears of Joy” alone accounting for 20 % of usage.

From Static Icons to Dynamic UGC

As internet infrastructure evolved from one‑way content delivery to interactive platforms, users began creating their own emoji packs. This shifted production from primarily professional‑generated content (PGC) to a mix of PGC and user‑generated content (UGC), exemplified by memes such as “暴走漫画” and the rise of dynamic, image‑plus‑text stickers.

The development of emoji is tightly linked to hardware capabilities; each generation of devices expands the possibilities for richer visual communication, turning simple facial symbols into a complex, multimodal language that complements text.
