This is a submission for the World's Largest Hackathon Writing Challenge: Building with Bolt.
🏠 HomeWhisper – Whisper Your Home to Life
Inspiration:
Managing multiple smart devices across scattered apps felt fragmented and exhausting. We wanted a unified, intelligent control hub that responds to you — your voice, your gestures, your habits.
Thus, HomeWhisper was born — a futuristic, AI-powered smart home command center that listens, learns, and adapts.
🔍 Project Details
HomeWhisper is a multimodal smart home dashboard that allows you to control and automate your entire home using:
- 🗣️ Natural Language Voice Commands (via Gemini API)
- ✋ Real-time Hand Gestures (via WebRTC + Computer Vision)
- ⚡ Predictive Automation (based on usage patterns)
- 📊 Energy Optimization + Security Monitoring
- 📱 Cross-platform, responsive design

⚙️ How We Built It (with Bolt at the Core)
- React 18 + TypeScript — Frontend foundation with type safety
- Tailwind CSS + Framer Motion — For sleek glassmorphic UI + microinteractions
- Gemini Flash API (via Bolt) — For fast, context-aware voice command interpretation
- Computer Vision + WebRTC — Gesture recognition powered by client-side models
- Firebase + Recharts — Real-time state sync and visualization
- Vite — Lightning-fast dev server
- Modular Design System — Built for scale and component reusability
🧠 Technical Challenges & Breakthroughs
🎙️ Challenge 1: Voice + Gesture Conflict
Problem: Integrating voice and gesture commands without triggering overlap
Breakthrough: Used state flags to manage input mode context, allowing smart fallback between modalities.
🤖 Challenge 2: Real-time AI Interpretation
Problem: Users speak differently; context matters.
Breakthrough: Gemini via Bolt let us train and test multi-turn prompts for contextual command parsing.
📱 Challenge 3: Unified Cross-Platform UX
Problem: Mobile and desktop gesture/voice interactions needed different ergonomics.
Breakthrough: Designed responsive interaction zones + adaptive gesture thresholds per device type.
