According to CNBC Sony filed application for a patent that will allow users to use a contact lens type camera module which could be controlled by intentional blinking.
So what is behind Sony’s patent? well, the concept is pretty simple (in theory at least) a contact lens like device will be used on the eye by the user who will be able to activate it using things such as blinking. The technology will known how to distinguish between voluntary and involuntary blinking and take a picture only when a voluntary blinking is registered.
Unlike somewhat similar patents applications by other companies including Google, the Sony patent seems to be more focused on photography, with mechanisms for changing aperture, zoom, focus and a way to perform image stabilization and transfer images to a mobile device.
