Apple has filed for a patent (number 20180317839) for “adjusting alarms based on sleep onset latency.” It involves human sleep detection on devices such as the iPhone, iPad, and Apple Watch.
Most people require a certain amount of sleep at night to feel well rested the following day. Often, when a person works, the person will set an alarm to wake them up at an appropriate time so that they can arrive at work on time. To get sufficient sleep, the person will go to bed at a time that allows for an appropriate amount of sleep (e.g., 7 hours, 8 hours, etc.).
However, most people do not fall asleep right away when they go to bed. So, even if the person goes to bed at an appropriate time to provide 8 hours of sleep, the person often only ends up with 6 or 7 hours of sleep when the alarm goes off in the morning. Apple has an idea to change this — although it might make you late for work or school!
Here’s Apple’s summary of the invention: “In some implementations, a mobile device can adjust an alarm setting based on the sleep onset latency duration detected for a user of the mobile device. For example, sleep onset latency can be the amount of time it takes for the user to fall asleep after the user attempts to go to sleep (e.g., goes to bed). The mobile device can determine when the user intends or attempts to go to sleep based on detected sleep ritual activities.
“Sleep ritual activities can include those activities a user performs in preparation for sleep. The mobile device can determine when the user is asleep based on detected sleep signals (e.g., biometric data, sounds, etc.). In some implementations, the mobile device can determine recurring patterns of long or short sleep onset latency and present suggestions that might help the user sleep better or feel more rested.”
Of course, Apple files for — and is granted — lots of patents by the U.S. Patent & Trademark Office. Many are for inventions that never see the light of day. However, you never can tell which ones will materialize in a real product.
