Ask HN: How would you design an alarm for sleeping bus drivers?
There was an accident recently here in Turkey when the bus driver fell asleep. Several people died including the driver. This happens too frequently in the cut-throat industry of transportation. How would you design a system to trigger an alarm when the driver shows signs of falling asleep? What would you try to catch? His closing eyes? His nodding? Or something else?

- tyingq 9y agoThere are different approaches, things like cameras, brain wave monitoring, etc. I would guess the ones that use heart rate would be the least expensive and easiest to retrofit. No idea how the different approaches perform though. Here's one that seems well suited for retrofit: http://www.plesseysemiconductors.com/products/warden/ http://www.plesseysemiconductors.com/products/warden/

- nyc111 9y agoThis doesn't seem to be true. I wrote to FitBit and this is their answer: "... unfortunately the Fitbit trackers can't notify you when you are falling asleep. They have only silent alarms, which you can setup manually and reminders to move for every hour. The tracker vibrates on your wrist, reminding you to stand up and walk.
