If you are not a passionate hacker, don’t rush to the electronics store though: these Brain-Computer Interface (BCI) devices have still years of development to go before reaching operational maturity: the historical Twitter message took several minutes to compose and send, so don’t plan to write a long love or business telepathic letter just yet. Similarly, the EPOC interface only permits very basic actions in videogames and virtual worlds at this moment, and in controlled conditions. But, of course, this will change fast. There is money to make with the countless applications of BCI technology, and our understanding of the brain, though still very limited, has already reached a critical mass.

Of course, the most natural user interface of all would be when the computer can read your mind with no effort on the user’s part. This is the promise of research around brain-computer interaction. Gaming is one of the first areas where we could see this type of interface come into play. In fact, a company called NeuroSky already offers some level of brainwave sensing for game play. But brain-computer interaction could do so much more than operate games. At Microsoft, for example, we’re thinking about how a computer could tailor the information it’s presenting based on a user’s state.
