I've wondered before whether something similar could be implemented to help foster focus & "flow", for those of us working at computers.
By which I mean less measuring actual drowsiness, but more "lack of focus" as detected by your facial expression (perhaps also mouse movements + current open app?). This likely wouldn't be a binary thing but rather a more fluid "guide" which notices you're beginning to lose focus and guides you back to your "best next action".
Obviously intrinsic motivation is far more beneficial than external, but still it seems that something like this could be helpful (to me at least).
