Sensorimotor Based Brain Computer Interface

Not Applicable

Terminated

• Conditions: Healthy Volunteers
• Interventions: Other: Brain computer Interface Mu (SMR) rhythm

• Registration Number: NCT02169375
• Lead Sponsor: University of Michigan

Brief Summary

Sensorimotor (also know as mu) rhythm based brain-computer interfaces (BCIs) are a tool for controlling electronic devices using only brain signals. Often, the computer software that analyzes mu-rhythm brain signals constantly adapts to the individual user's brain signals when the training target location is known. The investigators want the BCIs to be more universal, and not depend on knowing the target location. Therefore, the investigators will test the effect removing adaptation has on accuracy of using a mu-rhythm BCI.

Primary Outcome Measures

Name	Time	Method
Accuracy of a mu rhythm BCI using adaptation versus no adaptation.	10 times over 5 weeks	Accuracy with which subjects can select one of two targets after a 3-second time period. The accuracy for a run is calculated as the % of the trials in which the correct target is selected. The average accuracy will be calculated for each of the 10 usage sessions and changes over the sessions will be tracked.
