When it comes to introducing new features, Google is always up to something. Now they have released a new feature called Look to Speak, an accessibility service that will allow the users to control their device with their eyes.

Obviously, you cannot go ahead and start navigating through everything using your eyes, but the app lets you select from some preset list of characters, words, phrases, and actions by moving your eyes up, down, left, or right.
