Sem 1

Work Completed from July 25^th to November 7^th, 2011

During this period, I finished the first half of the project regarding literature review and information findings. I am now known 2 types of electrode placements for EOG in order to capture the vertical and horizontal movement of the eye. The circuit construction must consist of 3 filters; notch filter, high pass and low pass filter. For almost 10 weeks, I have read few projects on internet associated with EOG and assistive device. Every finding has contributed well to my project proposal presentation and to my future planning.

Work to be Completed by May 2012

First step in my next stage is to conduct lab session and investigate the EOG first hand. Next, I need to purchase electronics components, and construct EOG circuit and prototype. This will be completed by end of April 2012. I would also need to test the prototype and prepare my final project slide presentation and report. The entire project should be completed by the first week of May 2012.

Problems Encountered

The crucial part of the system is the conversion of EOG output to mouse input signal.  I need to conduct a thorough research; experiments and result analysis have to be conducted on input/ output of EOG and wireless mouse in order to achieve the objective of the system. Motion artifact might cause error to EOG output thus affect the mouse input. Experimental research will be conducted by testing the interface myself or with the help of course mates.
