App Composes Music Using the Power of Mind
Researchers have developed an application to help physically impaired people to surf the internet and write songs using the power of their mind.
Gernot Muller-Putz, a scientists at the Austria’s Graz University of Technology (TU Graz), developed the new brain-computer interface application that can help people compose music or write.
The application involves using an electrode-equipped cap to enable the measuring of brain waves. Users are presented with several options such as letters, pauses, and chords, which are seen flashing one after the other on a computer screen. The interface also enable stipulation of tone length and pitch. As the user makes a selection, the selected items appear on a separate music-composing programme, as notifications. Once the piece is ready, it can be played back using the software.
Muller said that “Some 20 years ago, the idea of composing a piece of music using the power of the mind was unimaginable. Now we can do it, and at the same time have tens of new, different ideas which are in part, once again, a long way from becoming reality.”
The application requires to be developed even further so that it reaches maturity to be applicable for daily activities.
The application was tested on 18 healthy subjects. All of these subjects had some basic musical and compositional knowledge, as they all played musical instruments. They underwent a short training session, after which each of them were able to successfully compose, see their melodies on the score and play them later.
This brain-wave identifying technology shows immense potential for the physically impaired, enabling them to perform activities such as compose music, write songs, and draft emails, which they otherwise, couldn’t have found easy.
