In this study, we present a method to remove ocular artifacts from electroencephalographic (EEG) recordings. This method is based on the detection of the EOG activation periods from a reference EOG channel, definition of covariance matrices containing the nonstationary information of the EOG, and applying generalized eigenvalue decomposition (GEVD) onto these matrices to rank the components in ...

This work select the features in high dimensional data using eye movements of reading and writing by ElectroOculoGraph (EOG) signals. EOG measures the changes in the electric potential field caused by eye movements. This work has three phases; the first phase identifies and removes noise from the signal. The second phase involves analysis of EOG signals by CBFS Feature Selection method and the ...

The design and development of cost effective rehabilitation aids is a challenging task for biomedical research community. The biopotentials such as EEG, EMG, ECG and EOG that are generated from human body help in controlling the external electronic devices. In the recent years, the EOG based assistive devices have gained importance in assisting paralyzed patients, due to their ability to perfor...

OBJECTIVE A fully automated method for reducing EOG artifacts is presented and validated. METHODS The correction method is based on regression analysis and was applied to 18 recordings with 22 channels and approx. 6 min each. Two independent experts scored the original and corrected EEG in a blinded evaluation. RESULTS The expert scorers identified in 5.9% of the raw data some EOG artifacts...

OBJECTIVES 1. To assess the reproducibility of eye movement velocity measurement using two methods: traditional electro-oculography (EOG) and infrared video-oculography (VOG) and, 2. Determine whether the normal values for unilateral weakness and bilateral reduction of caloric responses vary according to method employed. BACKGROUND Vestibular testing frequently involves measurement of eye mov...

A game using electro-oculography (EOG) as control signal was introduced in this study. Various EOG signals are generated by eye movements. Even though EOG is a quite complex type of signal, distinct and separable EOG signals could be classified from horizontal and vertical, left and right eye movements. Proper signal processing was incorporated since EOG signal has very small amplitude in the o...

PURPOSE To asses the retinal pigment epithelium (RPE) function measured by EOG testing in patients with neurofibromatosis type 1 (NF-1). Our preliminary EOG results suggested dysfunction of the RPE in individuals with NF-1. In order to confirm our initial results we performed EOG examination on a larger group of NF-1 patients. PATIENTS Studies were performed on 36 patients with clinically dia...

هدف اغلب سیستم های واسط مغز و کامپیوتر (bci)، کمک رسانی به معلولین حرکتی است. با توجه به اینکه اغلب معلولینی که بطور کامل فلج شده اند، همچنان قادر به کنترل چشم و مغز خود هستند، انتخاب سیگنال های الکتریکی چشم (eog) و مغز (eeg) برای کنترل این سیستم ها، آنها را برای اغلب معلولین کاربردی می کند. در این تحقیق یک سیستم bci تلفیقی مبتنی بر سیگنال های eog و eeg پیشنهاد شده است که سیگنال eeg به عنوان سو...

This paper describes a human-computer interface based on electro-oculography (EOG) that allows interaction with a computer using eye movement. The EOG registers the movement of the eye by measuring, through electrodes, the difference of potential between the cornea and the retina. A new pair of EOG glasses have been designed to improve the user's comfort and to remove the manual procedure of pl...
