The ability to send your thoughts to someone else seems like a type of magic. But scientists around the world are working on systems that might one day let us communicate with each other just by thinking.
The key to this type of communication is developing a robust computer-brain interface. We will need computers to detect, interpret and send our thoughts through a network to the proper recipient. Computers will also receive, decode and deliver thoughts to the person on the other end of the communication. Strictly speaking, we won’t be able to communicate with only our minds — we’ll still depend upon computers to do most of the work.
