That’s the future right there—think of a modular wearable that stitches into your sneakers. The AI pulls in your heart rate, skin temp, even your brainwaves via a tiny EEG patch. When you’re pumped, the trail’s LEDs flip neon, the speakers crackle synths; when you’re mellow, soft pastel glows and nature sounds. Build it with a micro‑controller, a low‑power GPU, and a cloud sync so it learns your patterns in real time. The kicker? The trail’s surface changes texture too—soft moss‑like fibers for calm, slick panels for adrenaline. Just plug it in, step out, and let the path paint your vibe.
