Probing Question: If a blind person gained sight, could they recognize objects previously touched?

Most people conceptualize the world largely based on sight, and would find it difficult to function using touch alone. Think about finding the keyhole on your car door at night, or locating that light switch in a dark room. Even if it's too dark to see, a seeing person uses his or her visual memory, along with the tactile sense, to navigate the physical world and accomplish the task at hand.
