Scientists are developing a brain-computer interface (BCI) that recognises a person’s affective state and plays music to them based on their mood. The duo from the universities of Reading and Plymouth believe the system could be used as a therapeutic aid for people suffering with certain forms of depression. Scientists are not asking the subject to be happy or sad. They want to recognise the subject’s state so we can provide the right stimulus.
The subject is not in control and this is a very unique feature. Traditionally, the user has had complete control over how a BCI system responds. The project would use an electroencephalograph (EEG) to transfer the electrical signal from the patient’s scalp via a series of wires to an amplifier box, which, in turn, would be connected to a computer. The computer would then generate its own synthetic music based on the user’s mental state.
