Development Of An Adaptive Brain Actuated Control Device For Enhancement Of The Human\Machine Interface

It is hypothesized that the BioLink, a brain actuated control device produced by Brain Actuated Technologies, Inc can be used as a controller to enhance the human/machine interface. Two technical objectives of this proposed effort will be to determine if there are ways to improve the accuracy and responsiveness of the BioLink interface through judicious use of selected control frequencies and through implementation of adaptive calibration schemes. Rule-based and Neural-network calibration schemes will be evaluated. A thrid objective will be to evaluate the effectiveness of various modes of BioLink control. The fourth objective will be to quantify the levels of accuracy and responsiveness achievable with the BioLink. The proposed study will be performed in three parts. Part I will be designed to evaluate subjects' abilities to control the BioLink at a number of selected control frequencies and to evaluate two different modalities of control at the selected control frequencies. Part II of the study will involve developing rule based and neural network based calibration systems which optimize the subjects' BioLink system parameters such as amplifier gain, window centering and thresholding. The effectiveness of the optimization schemes will be evaluated in Part III.
