In a patent, Canon explains how it intends to translate its Eye-Control Autofocus (AF) technology into a camera with an electronic viewfinder (EVF). The technology was originally developed for the EOS 5 SLR, and as such needed updating.
Want to focus your camera simply by looking at a particular area of the viewfinder? If you're a Sony shooter, you might be enjoying that feature as early as next year. The company is reportedly working on building Eye Tracking autofocus into its cameras, with the initial version arriving in a flagship camera sometime in 2014.
Using the human eye to control cameras isn't a new idea -- Canon used to offer eye-controlled focusing in its SLRs -- but designer Mimi Zou's Iris concept camera takes the concept one step further by having the camera be entirely controlled by the eye. Shaped like a lens, the photographer uses the camera by simply looking through it. Focusing, zooming, and snapping photos are done by looking, narrowing/widening the eyes, and blinking (respectively).
