This article presents a totally autonomous, embedded, wireless and portable brain-computer interface based on occipital alpha rhythms that operates in real-time and noninvasively. In order to achieve the simplicity and versatility of a wearable device, and independence from a computer, the acquisition and power stages were designed and implemented on a portable platform with embedded processing. The output signal of the system is an on-off logic state that is activated when the cerebral rhythm surpasses a threshold. An application isdeveloped in order to validate the platform, configuring the device to operate as an alpha rhythm switch that commands the click of a commercial wireless mouse connected to a computer as a conventional peripheral.
