User can take a photo by using eye-tracking technology. User now no longer have to use their finger when taking a selfie. We provide a eye-tracking technology for selfie-takers who have had difficulties of moving their finger while holding a Iphone. Many users have experiences of shaking their hand to put their finger on a shutter button, especially whose hands are relatively small to hold a Iphone. By capturing the photo with their eyes’ moving, users no longer suffer from problems regarding shaking hands. Specifically, if a user take their eyes on a target cha-gge-bi, they will get a selfie after 3 seconds automatically. And of course, they can move the target wherever they want on a screen.
