Electroencephalography or EEG is a very simple type of BCI/BMI. A non-invasive BMI method, it works via an array of electrodes glued to the scalp or held in place by a cranial device. It is easily portable, cheap, and produces relatively good general brain readings for a non-invasive method.

However, like all methods of its ilk that read only the brainwaves that make it through the cranium, it is imprecise enough that it cannot detect specific commands; only general intentions. It requires considerable time to learn to use any EEG input system, as the user has to learn a series of strong thoughts, and concentration ability on those thoughts such that the EEG can pick them up with reasonable accuracy. Also, the EEG system needs to be calibrated in turn, to each individual user.
