Case study BK is a teenage male who suffers from severe cerebral palsy, making communication very difficult using his current assistive technology. His performance with a manual switch was compared to a hands-free system for computer interaction (Cyberlink Brainfingers/ NIA). BK uses a switch scanning menu, which steps through predetermined options till he chooses the current option being read aloud by pressing a button. A yes/no menu was used for the switch scanning interface for both manual and hands free conditions, as well as the point and click condition. In both hands-free conditions, BK was as fast and accurate as …

BCI (Brain-Computer-Interface) devices on the market today, such as the NIA, have the capability to assign computer commands to specific channels (e.g., EMG, EOG, Alpha, and Beta) associated with different methods of control. However, the utility of this capability is dependent on the ability of users to selectively/independently control the specific channels. The NIA system was evaluated to determine if independent control of its channels is possible. Two users with varying levels of experience were used in this study. The users played pong using each of the channels to control the pong paddle, while the data on the activation levels …
