Introduction

SilverChat is a voice-first AI assistant with accessible typography and high-contrast design for older adults.

• Target users: North American seniors 65+
• Core problem: Existing AI apps lack accessibility
• Solution: Voice-first + high-contrast visual interface </aside>

Problem Statement

<aside> <img src="/icons/light-bulb_gray.svg" alt="/icons/light-bulb_gray.svg" width="40px" />

While AI assistants like ChatGPT, Claude and Deepseek have become mainstream tools, they remain largely inaccessible to seniors due to small fonts, complex interfaces, and lack of consideration for age-related needs. This project envisions creating an AI assistant that older adults can use independently and comfortably.

Phase 2: Design Exploration (Nov 2025)

• Information architecture
• Low-fidelity wireframes
• Interaction flow design
• Accessibility testing (font sizes, contrast ratios)
• High-fidelity visual design
• Style guide development (SF Pro typography system, color schemes)

Phase 3: Prototyping & Testing (Dec 2025)

• Interactive prototype creation
• Usability testing with senior users
• Iterative refinement
• Final deliverables and documentation

Research Plan

<aside> <img src="/icons/light-bulb_gray.svg" alt="/icons/light-bulb_gray.svg" width="40px" />

This project employed a mixed-methods approach combining secondary research, competitive analysis, and primary user testing to inform SilverChat's design decisions. The research was structured in three phases: exploratory research, design development, and validation testing.

</aside>

Phase 1: Exploratory Research

1.1 Literature Review: Studied age-related visual changes and WCAG accessibility standards.

1.2 Competitive Analysis: Analyzed ChatGPT, Claude, and Google Gemini for accessibility gaps

1.3 Target Audience Analysis: Defined needs of 65+ North American users

Phase 2: Design Development

2.1 Design Principles Establishment: accessibility-first design principles

2.2Typography Hierarchy Research: typography hierarchy (40/28/22/18pt) based on iOS Dynamic Type

2.3 Color Palette Development: Created warm color palette achieving 15.8:1 contrast ratio

Phase 3: Validation Testing

3.1 Prototype Development: with Figma prototype + semi-structured interviews.

3.2 Usability Testing: Navigation, readability assessment, environmental mode testing

**3.3 Data Analysis:**Thematic analysis of qualitative feedback
