Abstract: A mind-controlled switch is described, which comprises input circuitry for receiving mind state data from a first external device, an actuator, responsive to user actuation to set one or more threshold mind state values, and control circuitry for controlling a second external device in dependence on the mind state data and the mind state value(s). Notably, the mind-controlled switch is provided separately both from a first external device (which actually collects the mind state data from the user) and the second external device, which is the device being controlled by the switch. Accordingly, the second external device need not have its own mind-controllable functionality, but can instead be a conventional device which is imbued with this functionality by way of the separate mind-controlled switch.

Abstract: A method of controlling a video clip player is described. The method comprises sending a control signal from a controller to the video clip player to output a pre-recorded video clip to a display; using a sensor to sense EEG signals from the brain of an observer of the displayed video clip; transmitting the sensed EEG signals from the sensor to the controller; processing the received EEG signals to determine an outcome, the outcome being achieved by the received signal comprising a predetermined frequency or a predetermined combinations of frequencies of EEG signals above a threshold level for a predetermined period of time; and controlling the video clip player in response to the determined outcome. The controlling step comprises selecting a next pre-recorded video clip to be output by the video clip player from a plurality of stored pre-recorded video clips; and instructing the video clip player to output the selected pre-recorded video clip to the display for presentation to the observer.
