Imagine this scenario in the not-too-distant future. You're awakened at 6:11 a.m. by the gentle sounds of tinkling bells and birdsong, even though you live in a 12th-floor apartment. Your alarm clock uses radar to track your breathing, and wakes you gently, with sound and light, when it detects you're in a lighter phase of sleep. Your transition to wakefulness triggers a cascade of changes in your apartment. In the kitchen, coffee starts brewing.
