Sensorimotor Rhythm Brain-Computer Interface Switch to Operate Assistive Technology
The purpose of this research is to develop tools to help people who are paralyzed. These tools are called brain-computer interfaces (BCIs). BCIs would allow a person to use brain signals to operate technology. Specifically this project's goal is to design a BCI to operate a switch.

|Official Title:||Sensorimotor Rhythm Brain-Computer Interface Switch to Operate Assistive Technology|
- Accuracy of Using the BCI as a Switch to Select From 4 Targets Using Scanning [ Time Frame: 8 sessions over 2 months ] [ Designated as safety issue: No ]Average accuracy for selecting one of 4 targets with a switch operated by a brain-computer interface controlled by power in the sensorimotor rhythms. The 8 sessions were conducted over a 2 month period. Accuracy was calculated as the percentage of trials in which the target was correctly selected. Trials for all sessions were combined to create the overall average. Therefore, there is no standard deviation. .

|Experimental: Pilot Testing||
Device: Brain Computer Interface Switch
Subjects will wear an EEG cap for 1-2 hours typical per session and use the brain computer interface to operate assistive technology. Subjects will be asked to participate in 14-20 sessions.
The investigators want to make a BCI that can be used to operate commercially available technologies for communication, environmental control or computer access. The BCI would replace a switch to let people operate these technologies without moving. However, investigators need people to test the BCI so they can determine how effective it is in replacing a switch.
