Effects of an Eye Massage Device towards Electrooculography Signals

Electrooculography signal is a bio-signal potential instrument obtained by an EOG acquisition device. The signals were divided into vertical and horizontal signals according to the channel and the placement of electrodes respectively. This paper is to investigate the differences in absolute mean values of the EOG signals before and after using an eye massage device based on four EOG tests designed. The first test conducted is relaxing and blinking which is useful in distinguishing between the actual EOG signals and signal artifacts. Secondly, smooth tracking allows us to to track slow and distant moving object. Thirdly, eye movement detection is controlled via reflexes which linked to the detecting vestibular system. Lastly, saccades occurs when the subject reading a paragraph. Based on the results, for relaxing and blinking, smooth tracking, eye movement detection and saccades, the values of confidence level obtained by using t-test statistical method were 97.8 %, 99.9 %, 99.7 %, and 100 % respectively.
