The Distributed & Interactive Systems (DIS) group at Centrum Wiskunde & Informatica (CWI) is conducting a survey about the utility of personal trackers for monitoring and visualizing sleep quality. Your participation will help us better understand and build personalized sleep quality monitoring systems.
To participate, you should have used a personal sleep tracker (e.g., Fitbit, Beddit, Jawbone) for at least one week sometime during the last two years.
The survey is available at: http://sleepmonitoring.selfip.com/limesurvey/index.php/337557?lang=en.
The survey should take you around 15 minutes to complete, and you will enter a lucky draw for one of five $15 Amazon gift cards. We will notify the winners of lucky draw through email they provide in the survey.
Thank you so much and please feel free to share!
