A Universal Approach to Visualizing Emotional States in Information Systems
Towards Universal Visualisation of Emotional States for Information Systems
HCI Today summarized the key points
- •This article summarizes a study investigating how emotional states in information systems can be represented using color, size, speed, and shape.
- •The research team examined both basic emotions and a score-based emotion model to determine which visual elements best convey emotional states.
- •In a survey with 419 participants, some emotions showed relatively clear connections to specific colors—for example, anger mapped to red and shame to gray.
- •They also found a tendency for anger and joy to be expressed quickly and with larger changes, while shame tended to be expressed slowly and with smaller changes; however, there were fewer clear rules across different animation types.
- •The study identified several common patterns that could be used to express emotions, but it concludes that a fully universal standard that works for all emotions is still lacking.

Why Read This from an HCI Perspective
This article is especially meaningful for HCI and UX practitioners because it focuses on ‘how to present’ emotions rather than ‘what to use to recognize’ them. It shows how simple visual elements—such as color, size, and speed—affect how users interpret emotional states, and it provides a starting point for interface design that translates emotion-recognition outputs onto the screen. In particular, it prompts readers to consider why consistent representation matters and where misunderstandings can arise.
CIT's Commentary
What’s interesting is that this research focuses less on the emotion model itself and more on how the results should be read on the screen. Emotions don’t end once they become data; they are reinterpreted in the way they are delivered to users. As a result, finding rules for expressing emotions—like color or size—is not just a visualization problem, but an interaction design challenge. That said, ‘universal expression’ can easily shift in real products depending on cultural context, service context, and brand tone. In Korea’s messenger or platform environment, emotions tend to be read more subtly and context-dependently, so it may be more practical to design user-tailored expressions along with the pathways for user intervention, rather than aiming for a single correct answer. Ultimately, this kind of research should move toward asking ‘what is least likely to be misunderstood’ rather than ‘what is the prettiest.’
Questions to Consider While Reading
- Q.Among color, size, and speed, which element causes the least misunderstanding in real services?
- Q.When using emotion visualization, how should you design intervention controls that let users directly modify or drag the representation?
- Q.If cultural or platform contexts change, how much will the emotion-to-color mapping that looked ‘universal’ hold up?
