Im starting a project to create a unique headphones that remove the brain signals, and output visualization of his work on a smartphone, so it becomes possible to change the mood of the listener by managing music.
Of course this is not the only use of such garnityry. Also, the device allows you to control your smartphone - unlock screen, flipping pictures to make music louder or quieter, lock and unlock the screen.
Also can be used for health monitoring.
Please hit me up if you are interested in participating in this project.
