Question: will we ever be able to contol electronic devices with our minds?

The answer is Yes – and we already have examples of devices like this! In fact, recently some prosthetic arm or hand was controlled in such a way. To do this, we have to train a computer to recognises certain brain activity patterns by getting the person to repeat a task multiple times. Then, we use these ‘learnt’ patterns to tell a robot to react to such patterns whenever they occur by doing certain things. So, yes, in the future, you won’t have to say or do anything… just think it and your electronic glasses will take a picture/record a video,or even tweet for you!
