Designing Health Communication: The Role of Emoji in Visual Language

In the digital age, emoji have emerged as a dynamic visual language, transforming how we communicate on social media. Beyond casual chats, these symbols are being explored for their potential in more critical domains, such as health communication. A recent study delves into this innovative intersection, analyzing how emoji can enhance the design and dissemination of health information.

To explore this potential, researchers created a micro-database of 69 health-themed emoji. These symbols were meticulously designed to function across various parts of speech—nouns, verbs, and adjectives—making them versatile tools in constructing meaningful visual narratives. The study employed an information design experiment to evaluate how emoji could complement textual health information, paving the way for a richer, more engaging communication style.

The findings were both insightful and actionable. First, the study highlighted the importance of carefully managing the quantity, frequency, and placement of emoji in health messages. Overuse or misplacement can dilute the intended message, while strategic placement can enhance clarity and retention.

Second, the research examined the denotative aspects of emoji–word integration. By pairing emoji with corresponding words, communicators can create a visually reinforced message that resonates more effectively with diverse audiences, particularly those with varying literacy levels.

Third, the study emphasized the value of strategic positioning and repetition of emoji. Repeated use of certain symbols can establish a visual hierarchy, drawing attention to key points and structuring information in an accessible way. For instance, a heart emoji might repeatedly highlight cardiovascular health topics, fostering a visual anchor for readers.

This pioneering study offers theoretical and practical insights into the role of emoji in health communication. It underscores their potential not only as decorative elements but as powerful tools in information design. By integrating these visual symbols judiciously, communicators can make health information more accessible, engaging, and memorable.

As emoji become an increasingly universal language, their thoughtful application in health contexts opens up possibilities for more inclusive and impactful communication strategies. This study marks a significant step forward in bridging design and health, demonstrating how innovation in visual language can drive better understanding and outcomes in public health.
