Sony aims to beam sights, sounds into brain

This article describes the technique will enable us to smell, taste, and touch in video game as virtual reality. Sony Corp. has obtained this patent. In addition, this technology helps person who are blind or deaf see a view or hear sounds without medicines.
In my opinion, I wonder if blind or deaf person can get satisfied in virtual reality even though this technology is safe to the human body. And I also think this technology might be too much for us if it is used in video game.
