How Emotional Design Drives User Engagement in Red‑Packet Campaigns

This article reflects on the role of user emotions in optimizing the red‑packet collection process, outlining key emotional design points and the value of emotions in product design.

Emotion and Emotional Value

Emotion is a psychological activity mediated by individual desires and needs, influenced by mood, personality, and external factors, which can produce positive or negative effects and trigger behavioral motivation. According to Robert Lipper’s motivation‑arousal theory, emotion is a sustained state that awakens and guides behavior.

Emotional value, as described in Predictably Irrational , is the ability to influence others' emotions; the more positive emotions a product generates for users, the higher its emotional value.

SCARF Model

David Rock’s SCARF model identifies five emotional needs that, when satisfied, make people feel happy in social contexts:

Status – feeling recognized and indispensable.

Certainty – receiving clear feedback and guidance at each step.

Autonomy – having control and freedom in the process.

Relatedness – authentic, emotionally resonant content that builds trust.

Fairness – perceiving a proportional balance between effort and reward.

Applying these needs to e‑commerce design yields five key design points:

Select products that match user aesthetics and brand identity for personalized display.

Provide timely feedback to enhance certainty.

Align user pathways with mental models while reducing constraints for autonomy.

Present authentic user scenarios to foster relatedness.

Create a strong sense of reward anticipation to ensure fairness.

These points correspond to Donald Norman’s three design layers—instinct (sensory attraction), behavior (process experience), and reflection (scenario depth).

Case Study: Red‑Packet Collection

Freud’s theory divides personality into id (desire), ego (reason), and superego (morality). Platforms exploit the id’s greed by offering attractive incentives (the "benefit") and clever lures (the "temptation") to drive participation, leading to viral growth, activation, conversion, and brand building.

Incentive – Attracting Users

Platforms combine high monetary benefits with persuasive messaging to maximize perceived value while managing costs, e.g., Pinduoduo’s "60 yuan no‑threshold" and "minimum 80 yuan" offers.

Guidance – Steering Emotional Behavior

Randomized red‑packet mechanics increase perceived difficulty and excitement, creating a "itch" that drives users to act, while subsequent reward comparisons amplify satisfaction (the "爽" feeling).

Control – Positive Feedback to Shape Emotion

Positive feedback at peak and end moments (peak‑end rule) shapes overall experience. Effective feedback includes not only success/failure prompts but also predictive cues such as recommended items after red‑packet receipt, influencing subsequent emotional states.

Conclusion – Driving Design Goals Through Emotion

Emotion is the motive behind behavior; it triggers needs and serves as the benchmark for product design. By understanding and influencing user emotions—leveraging human weaknesses, authentic scenarios, and the interplay of "itch" and "satisfaction"—designers can steer user actions, enhance engagement, and achieve strategic product objectives.
