Reflection

For the current prototype, I roughly count all the time a user spends on the pillow as sleep time, which might not be very accurate. I did some research on how to detect if a person is asleep or awake. A common method used by sleep monitor apps like Sleep Cycle is using the accelerometer inside the phone (the part that knows when you turn it sideways) to detect the movements as you sleep. To make the Smart Pillow smarter, I still need to do more experiments with different sensors to find out the best and most accurate way to collect information.
