Brain controlled music player
Imagine controlling your music player just with your brain. The ability to change songs or toggling the volume without even moving your hands. Yes, that is exactly what Engineers from the Department of Systems and Control Engineering and the Centre for Biomedical Cybernetics at the University of Malta have created. A brain controlled music player that was presented at the 6th International IEEE/EMBS Neural Engineering Conference in San Diego with the aim to make life easier for people with some kind of disability. This brain-computer interface (BCI) technology works by reading the user’s brain signal activity by placing electrodes at specific position in the head using electroencephalography (EEG). Thereafter when the user looks at specific boxes for controls such as volume, next song etc. which sends commands to the user by reading the brain activity. This BCI system developed by Rosanne Zerafa uses a unique brain pattern reading system, the same which occurs when person looks at flickering light called Steady State Visually Evoked potentials (SSVEPs).
So in a way when you need to change the song for example, you just have to look at the corresponding box and it will be done in a matter of seconds. To test the performance of this music player, users at Biomedical Engineering Laboratory, University of Malta were fitted with the device and it successfully controlled all the music elements without any flaws.
To make the system function in a flawless way, an app has been developed around the music player control. And not just controlling the music player with brain but this new system gives new insight into the functioning of brain and how to harness its power to control objects without even touching them.
