Introducing the Complete Course in Emotion-Driven Innovation (E-DI)
TrendClass: Emotion-Driven Innovation & Human Product Emotion Interaction in Fashion by Dhruva Tripathi is not just a book—it is a complete professional methodology
Built on proprietary F-Trend catwalk analytics and advanced consumer psychology, this B2B practitioner's playbook gives you the exact frameworks to design products that reliably trigger positive consumer appraisals
Inside this Practitioner’s Playbook, you will master:
The HPEI Framework: Map the exact sensory channels—Visual, Tactual, Multi-Sensory, and Audio—that carry emotion from your product to the consumer.
The 25 Positive Emotion Typology: Stop designing for a vague "positive mood." Learn to engineer 25 distinct emotional states—from Enchantment to Pride to Relief—and know exactly which design elements produce them.
The P2VP Model (Personality, Purpose, Value, Product): Discover F-Trend's proprietary architecture for aligning your specific target persona with the exact emotional trigger that drives their purchase behaviour.
The Emotion Index Mapping Tool: Learn how to turn objective colour data—Temperature, Saturation, Brightness, and Contrast—into predictable emotional intelligence.
The 3-Phase E-DI Process: Implement a repeatable Front End of Innovation (FEI) workflow that starts with an emotional target and works backward to material selection.
