Signal Processing And Information Fusing Algorithms For The Synthesis Of An Alternative Electromyogram/Eye Gaze Tracking Computer Cursor Control System, Craig Anthony Chin

FIU Electronic Theses and Dissertations

This research pursued the conceptualization and real-time verification of a system that allows a computer user to control the cursor of a computer interface without using his/her hands. The target user groups for this system are individuals who are unable to use their hands due to spinal dysfunction or other afflictions, and individuals who must use their hands for higher priority tasks while still requiring interaction with a computer.

The system receives two forms of input from the user: Electromyogram (EMG) signals from muscles in the face and point-of-gaze coordinates produced by an Eye Gaze Tracking (EGT) system. In order …

Subdural Electroencephalogram Analysis For Extracting Discriminating Measures In Epileptogenic Data, Mercedes Cabrerizo

FIU Electronic Theses and Dissertations

This dissertation introduces an integrated algorithm for a new application dedicated at discriminating between electrodes leading to a seizure onset and those that do not, using interictal subdural EEG data. The significance of this study is in determining among all of these channels, all containing interictal spikes, why some electrodes eventually lead to seizure while others do not. A first finding in the development process of the algorithm is that these interictal spikes had to be asynchronous and should be located in different regions of the brain, before any consequential interpretations of EEG behavioral patterns are possible. A singular merit …
