Brain Computer Interfaces (BCI) based on Electroencephalography (EEG) allow for the monitoring and analysis of ongoing brain activity in real time. The signals measured by this technology can be used to control user interfaces without the requirement of the human motor system. This technology can benefit those with paralysis and other severe disabilities. As of now, the majority of BCI systems are currently large and immobile, and therefore impractical for use in everyday life outside of a lab. There are several components to a BCI system such as data acquisition, a classification system, as well as stimulation, all of which must be made portable to create a portable BCI. To address this problem, we would like to focus on making a portable stimulator that can interact, through wifi, with the BCIs that are monitoring brain activity. The stimulator will consist of flickering LEDs at predefined frequencies, with attention to luminescence (we don't want our LEDs to blind the user so it must be at the right intensity for each user) as well as controls to adjust the frequencies while maintaining signals timing. Our design goals are to make the stimulation for the BCI and EEG portable and be integrated wirelessly so that users are not confined to just a lab setting and that the system could be tested and used in different environments. |
