This paper discusses a method for estimating sleep quality. It expresses the sleep quality as percentage. It is based on National Instruments LabVIEW. Two approaches are used to arrive at the sleep quality. Approach one involves quantifying the stress level that the subject is under. It is done by measuring the change in skin resistance which changes with stress. Stress levels have shown to have significant impact on sleep quality. Approach two involves design of an electrooculograph system. The EOG helps in detection of eyeball movement, hence helps in detection of Rapid Eye Movement (REM sleep) during sleep. REM sleep is generally associated with quality of sleep. Hence, the frequency of eyeball movements during sleep and the cycles in which they occur are used as an indication of sleep quality. The results from above mentioned approaches are integrated in program in LabVIEW using a suitable algorithm to give an indication of sleep quality. This project can be used for early detection and treatment of sleep disorders. © 2005 - 2013 JATIT & LLS. All rights reserved.
