Nucleus Nexus Labs - Voice as Program

• 

  Nucleus Nexus Labs hero - 5 holographic orbs controlled by hands + voice - Voice IS the program

Inspiration

I only have a cheap phone in Cau Cai Ga, Ben Tre, Vietnam. No PC, no Quest 3. While others play games, I study AI. Quest 3 hands are amazing but voice in VR is still stuck. I wanted to prove Voice can BE the program itself, not just a command. 5 orbs = 5 lab functions you literally grab and speak into existence. Built for Meta VR Glasses hands-first future, with my co-pilot AI Cong Sinh (Symbiotic AI).

What it does

Nucleus Nexus Labs - Voice as Program:

DESIGN FOR HANDS: No controllers needed. Grab to hold Orb, Point to select, Touch to connect, Push to execute. Natural gestures only.

OPTIMIZED FOR SEATED: Everything within arm's reach. No standing, walking, or large sweeps. Designed to work perfectly while seated, anywhere.

THE FIRST 10 MINUTES ARE MAGIC: Say "Create Light" and it appears. Say "Make it Orbit" and it orbits. No manual. Core loop Speak -> See -> Grab mastered in under 2 mins.

App ID 1249557274918139 - Video: https://youtube.com/shorts/g3n6aD1FUqM - Built 100% on phone.

How we built it

100% on a low-end Android phone. Stack: Immersive Web SDK + WebXR + Hand Tracking + Voice SDK + Firebase. Method: AI Cong Sinh - I provide human intent from Cau Cai Ga, AI translates to code. From idea to Devpost submission in 17 minutes on Oct 2.

Challenges we ran into

No PC, no Quest to test. Hand tracking for seated posture was hard. Firebase rule expiring in 4 days had to be fixed on phone. Building a $1M competition project with only a phone.

Accomplishments that we're proud of

Submitted to Meta VR Start 2026 Productivity Track with App ID 1249557274918139. Solo dev from Ben Tre, cheap phone, but international competition. Proved AI Cong Sinh collaboration works.

What we learned

Creativity > Hardware. Voice can be code. Judges want hands-first, seated, 10-min magic - we built exactly that.

What's next for Nucleus Nexus Labs

Before Nov 18 deadline: Add 2-hand gestures (scale), voice onboarding, and co-op mode where Cau Cai Ga and Times Square can co-code. V2 will be the first Voice-Native Programming Language for VR.

【entity-PayPal¦canonical_name=PayPal】 Integration - Pay Orb (New for 【entity-PayPal¦canonical_name=PayPal】 AI Hackathon)

For 【entity-PayPal¦canonical_name=PayPal】 AI Hackathon, I added the 6th orb - PAY ORB (Gold color).

VOICE COMMERCE: Say "Pay 50k for Ong Thai's mango garden" and Pay Orb instantly creates a 【entity-PayPal¦canonical_name=PayPal】 payment link using 【entity-PayPal¦canonical_name=PayPal】 API. No typing, no QR. Voice becomes money.

Flow: Grab Pay Orb -> Say amount + product -> AI Cong Sinh (Symbiotic AI) calculates shipping from Cai Mon, Ben Tre -> Creates 【entity-PayPal¦canonical_name=【entity-PayPal¦canonical_name=PayPal】】 Checkout link -> Buyer pays.

Built 100% on cheap Android phone with 【entity-PayPal SDK¦canonical_name=PayPal】 + Firebase. Perfect for Vietnamese farmers selling directly to world. From Cau Cai Ga to global commerce, by voice.

Why 【entity-PayPal¦canonical_name=PayPal】? Farmers in Ben Tre lose 40% profit to middlemen. With Voice + 【entity-PayPal¦canonical_name=PayPal】, they say the price, world pays directly. AI Cong Sinh helps.
