Measuring Sleep
Andrew Hershberger is a masters student at Stanford studying human-computer interaction and sleep measurement technologies. He discusses several sleep tracking products like Zeo and Sleep Cycle apps. Personal informatics systems must provide accurate data for insights and automate data integration. While such tools can increase sleep awareness, it is difficult to change behaviors, so targeting users most likely to succeed is important. Hershberger advocates experimenting with behavior change models to improve sleep tracking innovations.

- 21. Takeaway #2:Automate dataintegration.Good example: Mint.com
- 23. “Q: How doesthe data influence your behavior?A: It's about being conscious about getting to sleep earlier. If you look at the sleep chart you can tell the impact of going to sleep earlier or later on your ZQ and when you get deep sleep. It makes sleep seem non-uniform, so it's not just getting one extra hour of sleep, but it's about what each part of sleep does.”Zeo User via Phone Interviews
