If that wasn’t easy enough, the researchers Shaowei Chu and Jiro Tanaka at the University of Tsukuba’s Department of Computer Science in Japan are working on a new technology that incorporates the use of hand gestures to take a photo by hooking the device on to cameras and uses a computer vision algorithm to recognize hand gestures and take the photos. As it stands the device is too large to be attached to regular cameras but the researchers have said that it is starting to look promising. Hopefully, instead of an external device, they will soon find a way to incorporate the technology and algorithm into the camera itself.
