SLEEPTRACKER Alarm Watch: [via Street Tech 3/26/2005; 2:52:09 PM] Here's a review of a watch that wakes you right at the moment you should get up (based on your actual sleep cycle), in order to avoid feeling sluggish. The manufacturer doesn’t tell you exactly how it "continuously monitors signals from your body that indicate whether you are asleep or awake" or almost awake, but it evidently does a good job of it. One can make an educated guess and infer that it monitors your temperature, or pulse, or even the electrical differential of your skin, or all three, or something else. At any rate, it supposedly tracks your sleep. According to the reviewer, it actually works and left him feeling refreshed on a lot less sleep. The review's comments are worth reading too.
