Hello and thank you for deciding to fill out this survey. We are a group of students with a new business idea and we are doing a survey to see how many people are interested in our product. We are developing an intelligent sleeping pillow which can monitor your sleep phases and wake you up at the most optimal time during a set half hour interval (when it is easiest for you to get up). Pillow can be wirelessly connected to an external device which can be used to analyze your sleep data and as an alarm clock. A product with similar features already exists in a form of wrist watch (http://www.sleeptracker.com/).
