Bridging the Web and the Physical world
summary
Demonstrates concrete browser-to-device tooling: Web Bluetooth (BLE, HTTPS + user gesture, connect to peripherals for GATT reads/notifications), WebUSB (powers device, boots ≈3s, deploy JavaScript instantly; shipping on Linux/Mac/Windows/Android), Generic Sensor API (accelerometer/gyro fused, 61 lines to bridge a Daydream controller over BLE), and Eddystone/NFC for URL bootstrapping and tag read/write. Shows progressive web apps and service workers for offline low-friction flows, origin-trial tokens for early API access, and barcode/shape-detection APIs coming soon.
