**1. Emotional UX Design – Theories & Books 📖** 💡 **Theory:** Emotional UX is based on **psychology, cognitive science, and user behavior research.** Some foundational concepts include: **A) Don Norman’s Three Levels of Emotional Design** _(from the book_ **_“Emotional Design: Why We Love (or Hate) Everyday Things”_**_)_ **1. Visceral Level** (Instinctive Reaction) – First impression, visual appeal. **2. Behavioral Level** (Ease of Use) – How intuitive and engaging the experience is. **3. Reflective Level** (Deeper Meaning) – How the app builds a long-term emotional connection. 🔹 **Example:** Apple products feel “premium” at a **visceral level**, work seamlessly at a **behavioral level**, and create strong brand loyalty at a **reflective level**. 📘 **Book Recommendation:** ✅ _Emotional Design: Why We Love (or Hate) Everyday Things_ – Don Norman • This book explains how **design evokes emotions** and why people feel attached to certain products. 📘 **Other Books:** ✅ _Design for Emotion_ – Trevor van Gorp & Edie Adams • Explains **how emotions influence user behavior** and how to design experiences that **connect with people**. ✅ _The Design of Everyday Things_ – Don Norman • This is a **UX classic** on how people **interact with technology** and why usability + design thinking matter. --- **2. Conversational UI – Theories & Books 💬** 💡 **Theory:** Conversational UI is based on **linguistics, psychology, and AI-human interaction research.** **A) Grice’s Cooperative Principle (How Conversations Work)** _(From linguistics & AI research – Paul Grice, 1975)_ When humans **talk to each other**, they **follow four key principles**: 1️⃣ **Maxim of Quantity** – Give enough information, but not too much. 2️⃣ **Maxim of Quality** – Be truthful and reliable. 3️⃣ **Maxim of Relation** – Keep things relevant. 4️⃣ **Maxim of Manner** – Be clear and easy to understand. 💡 **Why This Matters in UX:** A **Conversational UI** should follow these principles. If an AI chatbot **gives too little or too much info, is unclear, or irrelevant**, it **feels unnatural** to the user. 📘 **Book Recommendation:** ✅ _Designing Voice User Interfaces_ – Cathy Pearl • Covers **how to create conversational AI** that feels **natural and human-like.** ✅ _Conversational Design_ – Erika Hall • Explains how **UX writing, chatbot design, and digital interactions** should follow human conversation principles. ✅ _Talk to Me: How Voice Computing Will Transform the Way We Live_ – James Vlahos • Talks about how voice assistants (like Siri & Alexa) **mimic human communication** and why some feel more engaging than others. --- **3. UI & UX Guidelines from Industry Leaders** Apple, Google, and other big tech companies have **official design frameworks** for UI/UX: 📘 **Apple’s Human Interface Guidelines (HIG)** • **Focuses on clarity, depth, and responsiveness.** • Read here: [Apple HIG](https://developer.apple.com/design/human-interface-guidelines/) 📘 **Google’s Material Design** • **Uses motion, micro-interactions, and dynamic elements** to create a more “alive” digital experience. • Read here: [Google Material Design](https://material.io/) 📘 **Nielsen Norman Group (NNG) – UX Research & Guidelines** • The **gold standard in UX research**—tons of articles on **psychology, usability, and human-centered design**. • Read here: [NNG UX Research](https://www.nngroup.com/) --- **4. Specific Techniques You Can Use for HOPES 🚀** Now that you have some **theoretical backing**, here are **practical techniques** that can bring **Conversational UI & Emotional UX** into the app: ✅ **“Empathetic Microcopy”** – Small, friendly text responses (e.g., _“I’m here for you”_ instead of _“Invalid input”_). ✅ **“Micro-animations”** – Subtle UI elements that make interactions feel **alive** (e.g., button presses with soft feedback). ✅ **“Conversational Flow Design”** – Instead of static menus, let users **choose guided responses**, like a supportive digital case manager. ✅ **“Emotional Color Theory”** – Colors can influence mood (e.g., warm tones for comfort, cool tones for focus). --- Related: [[Article - Finding love in algorithms - deciphering the emotional contexts of close encounters with AI chatbots]]
