10.5. Brain-Computer Interfaces
Perhaps the ultimate interface to computers would be a direct link to the thoughts and intentions of the user, a "Your wish is my command" model of interaction, involving no physical action or interpretation of any kind. While this kind of mind-reading technology is not likely to be developed in the foreseeable future, the nascent research area of brain-computer interfaces (BCI) is perhaps a step in this direction. BCI technology attempts to perceive commands or control parameters by sensing relevant brain activity of the user. While not fitting completely within the perceptual interface model of natural human-human interaction, BCI may eventually be an integral component of perceptual interfaces. The computer ...
