WEEK TWO

Bismillahirrahmanirrahim.

As I promised, this week's post will be the 'lab session with me'. My supervisor told me to do the laboratory session for EOG test. The lab session was done on Wednesday 23rd of February. This lab session is to prove the polarity of the rolling eyes and the voltage differences. 

The lab session was not running smoothly actually. I went to the lab at 11 am. And I had class on 12 pm. So, I only have one hour to do the lab. But, in all time I took most of the time left to complete the EOG circuit with the help of my friend and the technician as I was not really prepared. As the circuit finished, I tried to get the result. Below are the pictures that I captured.

result two

result three

Result one, result two and result three show the results which I got on the 'lab session'. Result one shows the result when eyes were blinking simultaneously while result two shows the result when eyes were turning from right to left simultaneously. Result three shows the result when eyes were rolling from upward to downward simultaneously. The reading taken for each waveform is four to five readings. The result I got were not very good. 

applying the EOG electrode

In this experiment, I use four channel electrode configuration for taking the EOG reading. The horizontal electrodes were placed on my right and left eyes each while the vertical electrodes were placed on upper and lower of my right eye. The reference electrode was placed on the center of my forehead. 

I think I want to do this experiment again to check and re-check the waveform produced. Also, I want to take the voltage range for the EOG measurement. 

Barakallah.
