The challenge with stay awake alarms is determining when the driver is sleeping with their eyes open - a common occurrence. Brain activity is the best way to gauge this. The proposed idea uses the senses that are not normally used when driving to determine cognitive activity: hearing and speaking.
It
works like a game. The device makes a pattern of beats, and then the driver repeats the beats with their mouth with an additional 2 beats at the end. A headrest mounted microphone facilitates the process. If the incorrect response is not provided quickly enough a loud alarm wakes up the driver.

Better to detect faltering senses and drifting cars, methinks. Don't want the sleepy driver so focussed on matching the beat s/he misses the deer in the road. |

Another distraction for drivers, just what we need. Even if you mean for this to somehow sense when the driver is sleepy and only activate then, there are still beter ways. Look up Lane Departure Warning by Nissan and see if it might look a little more practical. |

Maybe we should outlaw car radios. |

I sing with the radio when I get tired on the road - works wonders. Keeps me focused on the road, not distracted from it. Repeating a simple beat seems a lot less distracting than singing the words to a song. |

Yeah, I'm sure you can get that installed in your 2001 GM Pickup. |
