Firstly,I guess you need to know more about the brain waves.The combination of millions of neurons sending signals at once produces an enormous amount of electrical activity in the brain, which can be detected using sensitive medical equipment (such as an EEG), measuring electricity levels over areas of the scalp. The combination of electrical activity of the brain is commonly called a Brainwave pattern.

Coming to the main topic by using these brain waves we can control the objects….You can understand this more easily by checking this video out….
So,in other words we can say that we ourself are controlling the television set without remote.But,only with our thought..!!
