Human-Computer Interaction via Brainwaves for Disabled People

The idea of interacting with computers using only the human brain quickly emerged after the discovery of electroencephalography in 1929. Although plenty of research has been done related to this subject, and several consumer based products are already being sold, little importance has been given to mobile devices, which are rapidly dominating the per-sonal computing scene.

With this in mind, an Android application was developed in this project, attempting to facilitate the usage of mobile computers for disabled people. Using exclusively electric activity acquired from a brain computer interface device, different types of interactions were experimented, expecting to improve the mentioned people’s autonomy and quality of life.

The users of the application were able to control several features just by winking, which achieved over 87% success rate after a short calibration session. Additionally, the application was able to discriminate the users’ state of mind when subjected to different conditions. Four situations were tested, all of them exhibiting unique neural oscillations patterns, making the application accurate in understanding how the user was feeling.

To conclude, the main contribution of this project was creating a type of interaction that was not previously available, and, although more limited, presented a higher success rate than the chosen device’s native application.
