Phone cases with embedded pico projectors that transform your cupped palm into a personal heads-up display.
Navigation arrows, payment QR codes, and quick notifications project onto your hand when needed—keeping your phone securely in your pocket during active moments like cycling, commuting, or shopping.
You're cycling through an unfamiliar city and instead of dangerously fumbling with your phone, you simply cup your left hand and a glowing blue arrow appears on your palm, pointing exactly where to turn—like having a tiny, personal traffic signal floating on your skin that updates in real-time as you move.
