MVP Plan

Goal

Validate that people engage with UV sunscreen visualization and will pay for it. One summer, one location.

MVP: Mirror on a Cart

Hardware (~$500)

  • Regular mirror (not two-way)
  • Modified UV camera (cheap donor camera + IR/UV filter removal + UV-pass filter)
  • Laptop or Raspberry Pi for processing
  • Small display (10-15”) mounted beside mirror
  • Battery pack
  • Cart/stand

What It Does

  • Live UV camera feed on screen, mirror beside it
  • User looks in mirror, glances at screen to see UV map
  • Basic false-color processing (dark = covered, bright = exposed)

What It Doesn’t Do (Yet)

  • No two-way mirror overlay
  • No depth cameras or walk-by detection
  • No payment terminal
  • No solar/cellular
  • No sunscreen vending
  • No forecast projection

Validation Plan

  • Roll cart to beaches, farmers markets, community health events
  • Offer free demos
  • Track: engagement rate, time spent, questions asked, interest in paying
  • Demo at a resort for a weekend → gauge B2B interest

Success Criteria

  • People stop and engage unprompted
  • Repeat visitors on multi-day events
  • Verbal willingness to pay for full sessions
  • At least one resort/venue expresses purchase interest

Next Steps After Validation

  1. Source two-way mirror + OLED for overlay prototype
  2. Add depth cameras for position tracking
  3. Build weatherproof enclosure (3D print housing components)
  4. Add payment terminal and cellular
  5. Solar power system
  6. Sunscreen vending integration
  7. NFC reapply reminder pad
  8. UV forecast projection feature
