This two fingers air camera is designed by Yeon Su Kim. The concept camera is operated by your fingers gestures. The images/videos are transferred to your smartphone via Bluetooth:
"If you want to click pictures, wear the camera band on your thumb and the shutter button on your forefinger and gesture to click a pic. To take videos, simply curve your fingers to mimic a video camera grip and shoot. The tension from the finger movement triggers the shutter button to operate."
