Emotions by Design

BIS Publishers • 2025

The Purpose

  • For decades, "Design for Emotion" remained largely academic. Designers and product managers knew that emotion drove user behavior but lacked systematic methods to design for it.
  • Together with my long-time collaborator Prof. Pieter Desmet, I wanted to bridge the gap between abstract psychological theory and the practical reality of product innovation—and make it accessible to a large audience.

Our Approach

  • I combined my 15 years of academic research and consultancy experience with Pieter's 25-year academic legacy.
  • We developed each topic together, balancing scientific rigor with accessible storytelling—creating practical tools design teams can use immediately.

What We Delivered

  • A 276-page handbook that establishes the state-of-the-art in emotion-driven design. Each chapter is structured around a "Law of Emotional Design."
  • Published in Europe in Nov 2025, USA/Asia to follow in Apr 2026.
  • Adopted as required reading in TU Delft's Design for Emotion curriculum.
  • Key frameworks: The 13 Fundamental Needs, Micro-Emotions, Need Laddering, and Emotion Diversity.

Key Topics

  • The 13 Fundamental Needs: A universal typology revealing the deeper needs behind every emotion—from Security and Autonomy to Beauty and Purpose.
  • Micro-Emotions: A framework for capturing the fleeting, subconscious feelings that drive user behavior and decisions.
  • Need Laddering: Technique for uncovering needs and identifying clashes between them, opening space for innovation.
  • Emotion Diversity: Framework distinguishing contentment from excitement, pride from satisfaction—enabling designers to evoke specific emotional experiences
